Law Updates

Subject

Summary: Smart meter manufacturers working with IS 16444 (Part 1):2015 now have a new BIS standard update to examine. The Bureau of Indian Standards ( BIS ) has established Amendment No. 4, August 2026, to the Indian Standard titled a.c. Static Direct Connected Watt-hour Smart Meter Class 1 and 2- Specification. The amendment was established on 17 August 2026. The BIS notification is dated 18 August 2026, while the Gazette carrying it was published on 25 August 2026. For businesses, the date that deserves immediate attention is 16 February 2027. BIS has allowed the standard without Amendment No. 4 to remain in force until that date. That does not mean every smart meter must be redesigned tomorrow. It does mean manufacturers, quality teams, suppliers and procurement teams should use the transition period to find out exactly what Amendment No. 4 changes and whether those changes affect their products, testing records, contracts or BIS-related compliance position. There is also an important limitation: the Gazette notification does not reproduce the detailed technical text of Amendment No. 4. Any clause-level technical conclusion must therefore come from the actual amendment, not from assumptions. Notification at a Glance Particular Verified Details Issuing Authority Bureau of Indian Standards Department Department of Consumer Affairs Document Type Notification regarding establishment of amendment to an Indian Standard Reference Number HQ-PUB015/1/2020-PUB-BIS (1588) Notification Date 18 August 2026 Gazette Publication Date 25 August 2026 Legal Basis Rule 15(1) of the Bureau of Indian Standards Rules, 2018 Indian Standard IS 16444 (Part 1):2015 Standard Title a.c. Static Direct Connected Watthour Smart Meter Class 1 and 2 Specification Amendment Amendment No. 4 Amendment Month/Year August 2026 Date of Establishment 17 August 2026 Standard Without Amendment Remains in Force Until 16 February 2027 Product Category Class 1 and Class 2 a.c. static direct-connected watthour smart meters Detailed Technical Changes in Gazette Not reproduced New Fee Not expressly specified New Penalty Not expressly specified Fresh Certification Requirement Not expressly specified BIS issued the notification under Rule 15(1) of the Bureau of Indian Standards Rules, 2018 and stated that the amendment listed in the Schedule had been established. The Schedule contains one standard: IS 16444 (Part 1):2015. It identifies Amendment No. 4, August 2026, records its establishment on 17 August 2026 and allows the standard without that amendment to remain in force until 16 February 2027. What is IS 16444 (Part 1):2015 for Smart Meters? The notification identifies IS 16444 (Part 1):2015 as the specification for a.c. Static Direct Connected Watt-hour Smart Meter Class 1 and 2. Put simply, the standard named in the Gazette relates to the Class 1 and Class 2 smart meter category described in its title. That scope matters. The notification should not be described as an amendment covering every electricity meter sold or used in India. It refers to a specific Indian Standard and a specific smart-meter category. The Gazette also does not reproduce the complete contents of IS 16444 or explain every technical expression contained in its title. Manufacturers therefore need the actual standard and Amendment No. 4 when carrying out an engineering or testing review. For compliance teams, the distinction is simple: The Gazette tells businesses that an amendment has been established and when the transition ends. The amendment document itself is needed to understand what technical requirement has changed. The Regulatory Framework Why BIS is involved The Bureau of Indian Standards is India's national standards body. In this notification, BIS is acting in relation to an Indian Standard and an amendment made to that standard. The document should therefore be read as a standard update. That sounds obvious, but it prevents a common mistake. A standards amendment, a Quality Control Order, a BIS licence requirement and a product-testing obligation are not the same legal instrument. The Gazette in this case establishes an amendment. It does not create an entirely new licensing scheme. Rule 15(1) of the Bureau of Indian Standards Rules, 2018 BIS expressly states that the notification has been issued in pursuance of Sub-rule (1) of Rule 15 of the Bureau of Indian Standards Rules, 2018. For this update, that is the legal basis cited by BIS for notifying the amendment appearing in the Schedule. The two-page Gazette does not explain Rule 15 in detail. Businesses should therefore avoid adding consequences that are not stated in the notification or established through another applicable official BIS instrument. Does an Indian Standard automatically mean mandatory BIS certification? Not necessarily. An Indian Standard tells businesses what specification or standard has been established. Whether compliance with that standard is legally compulsory for a particular product can depend on another regulatory instrument. Depending on the product and regulatory framework, businesses may have to look at: an applicable Quality Control Order the BIS conformity-assessment scheme product-specific certification requirements licence conditions a Scheme of Inspection and Testing a BIS product manual sector-specific regulations or tender and procurement conditions. The present Gazette should therefore not be used as proof that every manufacturer must immediately apply for a fresh BIS licence. What Has Changed Under the BIS Smart Meter Amendment 2026? The confirmed change is that Amendment No. 4, August 2026, has been established for IS 16444 (Part 1):2015. What cannot be confirmed from this Gazette is the exact technical content of that amendment. Area Position Before This Notification Position After the Notification Relevant Date Indian Standard IS 16444 (Part 1):2015 was already established Amendment No. 4 has now been established 17 August 2026 Amendment Version Amendment No. 4 was not covered by this earlier position Amendment No. 4, August 2026 is established 17 August 2026 Transition Existing standard continued Standard without Amendment No. 4 remains in force during transition Up to 16 February 2027 Technical Clause Changes Not available from this Gazette Not reproduced in this Gazette Actual amendment must be reviewed New Fees Not stated Not stated Not expressly specified New Penalties Not stated Not stated Not expressly specified This is where businesses need to be careful. The Gazette does not say that BIS has changed a specific accuracy requirement, communication protocol, display rule, testing method or safety parameter. Those details cannot be responsibly added without the actual text of Amendment No. 4. Which Smart Meters Are Covered? The Schedule names the following standard: IS 16444 (Part 1):2015 – a.c. Static Direct Connected Watt-hour Smart Meter Class 1 and 2-Specification. The direct product coverage therefore concerns smart meters falling within that standard. Businesses involved with other electricity-meter categories should not assume that this particular Gazette automatically covers their products. For companies dealing with Class 1 and Class 2 smart meters, however, the amendment deserves a product-level review. That review may involve manufacturers first, but the practical effect can extend further down the commercial chain. Suppliers may receive revised customer specifications. Testing teams may have to compare existing reports with amended clauses. Utilities may need to look at tender wording. Compliance teams may need to check whether existing BIS-related documentation needs any action. Those are possible business effects. They are not all direct duties created by this notification. Key Dates Businesses Should Record This update contains four dates that should remain separate. Event Date Practical Meaning Amendment No. 4 August 2026 Month and year assigned to the amendment Establishment of Amendment 17 August 2026 Date Amendment No. 4 was established BIS Notification 18 August 2026 Date appearing on the BIS notification Gazette Publication 25 August 2026 Gazette publication date End of Period for Standard Without Amendment No. 4 16 February 2027 Transition date stated in the Schedule The notification date and amendment establishment date are therefore not the same. Neither should automatically be replaced by 25 August 2026 merely because that is the Gazette publication date. The Gazette itself records these events separately. For an internal compliance tracker, businesses should record each date against the event it actually represents. What Does the 16 February 2027 Transition Period Mean? This is the part of the notification that matters most for implementation planning. The Schedule states that the standard without Amendment No. 4 shall remain in force until 16 February 2027. In practical terms, BIS has not removed the unamended version immediately. Manufacturers therefore have a period in which they can understand what Amendment No. 4 changes and decide what work, if any, is required for their products. That time can be used to: obtain the official Amendment No. 4 document compare revised clauses with current specifications identify affected meter models check existing technical documents review test reports against any changed requirements examine BIS conformity-assessment implications where applicable check production schedules review purchase orders and customer specifications and prepare for the position after the transition. These are sensible readiness measures. They are not presented in the Gazette as a mandatory eight-step government procedure. There is another point worth keeping clear: 16 February 2027 is not described in the notification as a sales-ban date. The Gazette says that the standard without Amendment No. 4 remains in force until that date. It does not separately say that all stock becomes illegal on 17 February 2027. What Does the Gazette Actually Tell Businesses? Despite the amount of business planning that may follow, the Gazette itself is short. It confirms: which Indian Standard is involved? the number of the amendment the month and year of the amendment when that amendment was established and how long the standard without the amendment remains in force. That is the confirmed regulatory information. The document does not provide a clause-by-clause technical explanation. This makes the next compliance task straightforward: businesses that work with IS 16444 (Part 1):2015 should obtain the amendment itself before making decisions about design, testing, certification or production. What Has Not Been Specified in the Gazette? There is value in being clear about what the notification does not say. Issue Position in the Gazette Detailed text of Amendment No. 4 Not reproduced Exact technical clauses changed Not expressly specified Revised accuracy parameters Not expressly specified Communication protocol changes Not expressly specified Cybersecurity changes Not expressly specified Revised testing method Not expressly specified Mandatory fresh testing Not expressly specified New BIS licence requirement Not expressly specified Fresh certification application Not expressly specified New application fee Not expressly specified New testing fee Not expressly specified New penalty Not expressly specified Mandatory stock disposal Not expressly specified Product recall requirement Not expressly specified Automatic licence cancellation Not expressly specified This is not a weakness in the notification. Its purpose is to notify the establishment of the amendment. The detailed technical material has to be read separately. For manufacturers, that means a product decision should not be based on a headline such as “BIS changed smart meter rules.” The precise amended clause matters. Does Amendment No. 4 Mean Manufacturers Need Fresh BIS Certification? The attached Gazette does not say so. Nothing in the two-page notification expressly states that every manufacturer must file a fresh BIS certification application because Amendment No. 4 has been established. Nor does it say that: all existing licences are cancelled every product has to be tested again each model requires fresh approval a fresh ISI Mark permission is compulsory or existing certified products automatically lose their status. The correct answer depends on the conformity-assessment framework that applies to the product. A manufacturer may therefore need to check the relevant BIS scheme, licence conditions, product manual, Quality Control Order or other official instructions before deciding what certification action is required. Where certification questions arise, working with a BIS certification consultant may help a manufacturer understand the filing and conformity-assessment position. But professional advice should begin with applicability, not with an assumption that a new certification application is automatically required. Impact on Smart Meter Manufacturers For manufacturers, the immediate job is technical comparison. A factory may already have product specifications, quality plans, testing records and customer-approved designs based on the existing version of IS 16444 (Part 1):2015. Amendment No. 4 creates a reason to check whether any of those documents are affected. The practical review may include: current meter models product specifications drawings and design records manufacturing instructions quality-control documents existing test evidence supplier specifications customer-approved specifications production plans and any relevant BIS records. Not every document will necessarily require a change. That can only be decided after the amended clauses are compared with the company's existing technical position. This is where a proper compliance gap assessment can be useful. Rather than changing everything, the business can identify only the areas that are actually affected. What Suppliers and Vendors Should Check The effect on suppliers can be less obvious but still important. A supplier may be working under a customer's technical specification rather than directly under the text of the Indian Standard. For that reason, supply teams should review how their contracts and purchase orders refer to IS 16444. Some documents may mention the 2015 standard alone. Others may use phrases such as “latest amendment” or “latest applicable version.” Those differences matter. A vendor should not assume that every ongoing supply arrangement changes automatically on 17 August 2026. Contract wording and buyer requirements need to be checked separately. Where supplies extend beyond February 2027, it would be sensible to resolve any ambiguity well before dispatch or tender submission. Impact on Quality and Testing Teams Quality teams are likely to be among the first internal departments asked, “Does anything need to be retested?” The Gazette alone cannot answer that question. It does not identify a revised test, changed testing frequency or new laboratory condition. The sensible approach is to compare Amendment No. 4 with the requirements used for the current product. If the amendment changes a clause connected with testing, the quality team can then check: whether the existing test report covers the revised requirement whether a new test is necessary whether the laboratory scope is suitable whether quality plans need amendment and whether product documentation remains consistent with the test evidence. This avoids unnecessary testing while reducing the risk of relying on evidence tied to an outdated requirement. Where laboratory work is genuinely required, businesses may use product testing and certification support or technical compliance consulting to coordinate the process. What DISCOMs and Electricity Utilities May Need to Review The Gazette does not issue a direct instruction to electricity distribution companies to rewrite their tenders. Still, utilities and DISCOM procurement teams may need to look at future specifications where IS 16444 (Part 1):2015 is referenced. The wording used in a tender can make a real difference. A tender may require: compliance with IS 16444 (Part 1):2015 compliance with the standard “as amended” compliance with the latest amendment compliance with buyer-specific technical specifications or additional technical conditions beyond the Indian Standard. Procurement teams should therefore check their own documents rather than assuming that the Gazette automatically rewrites existing tender conditions. The same applies to bidders. A manufacturer preparing a technical bid should confirm which standard version the tender actually requires before submitting test reports or compliance statements. Tender and Contract Implications Smart-meter tenders often contain detailed technical schedules. An amendment to a referenced Indian Standard can therefore become a contract issue as well as a standards issue. Businesses should review references to: IS 16444 (Part 1):2015 amendments to IS 16444 latest applicable standard technical specifications approved by the buyer manufacturer declarations product test reports and tender-specific compliance sheets. A tender issued before August 2026 may use wording different from a tender issued during the transition period. That does not mean one is automatically invalid. Each procurement document needs to be read on its own terms. For businesses regularly bidding for smart-meter supply contracts, tender compliance services can be useful where there is uncertainty about whether a technical bid refers to the correct standard or amendment. What About Existing Stock and Ongoing Production? The Gazette does not provide a detailed stock-clearance rule. It also does not say that meters produced under the earlier version must automatically be recalled or destroyed. That leaves manufacturers with a practical planning question: how should production, inventory and future deliveries be handled during the transition? The answer may depend on: the actual technical changes in Amendment No. 4 the product's BIS compliance position the date of manufacture customer specifications supply contracts tender requirements and any later BIS instruction that applies. Businesses should therefore avoid both extremes. There is no reason to assume that all existing stock suddenly becomes unusable. At the same time, it would be risky to continue long-term production without checking whether future supplies will have to reflect the amended standard. Technical Documents Worth Reviewing The notification itself does not prescribe a fresh documentation list. Still, once Amendment No. 4 is available, businesses may want to compare it with the records they already use to control the product. Depending on the clauses affected, relevant internal documents may include: product specifications design drawings quality plans test reports manufacturing instructions technical datasheets supplier specifications customer-approved specifications BIS-related records where applicable tender compliance sheets and internal change-control records. These should not all be described as mandatory documents. They are sensible records to review because a technical amendment can create inconsistencies if one document is updated while another continues to use the earlier requirement. Compliance Risks Businesses Should Avoid The greatest risk is not necessarily a penalty. It is making the wrong decision because the amendment has not been read properly. Some practical risks include: assuming the Gazette itself contains the complete amendment continuing to use the earlier specification without checking Amendment No. 4 redesigning a product before confirming what has actually changed assuming fresh BIS certification is compulsory without checking the applicable scheme assuming an existing licence means no action is required using old technical specifications in a tender that asks for the latest amendment ignoring customer-specific contractual requirements confusing 17 August 2026 with 16 February 2027 and waiting until February 2027 to begin the technical review. These are business and compliance-control risks. The notification does not prescribe a new fine or penalty for them. Benefits and Implementation Challenges The technical merits of Amendment No. 4 cannot be judged from this Gazette alone because its clauses are not reproduced. The transition arrangement, however, can be assessed. What Helps Businesses What May Require Work The earlier unamended standard does not disappear immediately Technical teams still need to obtain Amendment No. 4 A transition period is available Existing products may need a clause-by-clause comparison Manufacturers have time to plan verified changes Test evidence may need review where affected Procurement teams can update future specifications gradually Different customer contracts may refer to different versions Compliance teams can check certification implications before acting Several internal departments may need coordination The advantage is time. The challenge is making good use of that time. Is This a Right Decision or an Additional Burden? There is no honest way to judge Amendment No. 4 only from its title. The answer depends on the technical changes inside it. Why the Transition Period Helps BIS has given businesses a period during which the standard without Amendment No. 4 remains in force. That is more manageable than requiring every affected manufacturer to change its position immediately. A manufacturer can use this time to check engineering documents, testing records, production plans and customer requirements before making changes. For businesses with several meter models or multiple utility customers, that planning period can be particularly useful. Where the Extra Work May Come From Any standards amendment can create additional work if existing products are affected. A business may need engineering teams to study the amendment, quality teams to review testing, compliance teams to examine the BIS position and sales teams to check customer requirements. For smaller manufacturers, coordinating all of this can take time even where the eventual technical change is limited. There may also be additional testing or documentation work, but that should not be treated as confirmed until the actual amendment is examined. A Balanced View On the information available, the transition structure itself appears practical because BIS has not required the earlier version to disappear immediately. Whether the amendment becomes a minor technical update or a larger compliance exercise will depend on the clauses changed under Amendment No. 4. The safest business approach is simple: use the transition period to find out what has changed instead of assuming either that everything must change or that nothing has changed. What Businesses Should Do Before 16 February 2027 The notification does not prescribe an eight-step compliance process. Still, businesses can use the transition period in an organised way. 0 Recommended Action Team Purpose 1 Obtain Amendment No. 4 from the official source Compliance/Technical Understand the actual technical change 2 Compare amended clauses with current specifications Engineering/Quality Identify affected models 3 Check applicable BIS conformity requirements Compliance/Legal Understand certification impact 4 Review relevant test reports Quality/Testing Identify evidence gaps 5 Review customer and tender specifications Sales/Procurement Avoid contractual mismatch 6 Check ongoing production and inventory Operations Plan any required change 7 Align engineering, quality and compliance teams Management Maintain one interpretation 8 Complete verified changes before the transition ends Relevant Team Prepare for the post-transition standard position The first two actions should come before assumptions about testing, certification or redesign. Without the amendment text, a company does not yet know the size of the compliance gap. What Happens After 16 February 2027? The Gazette gives a clear endpoint for one thing: the standard without Amendment No. 4 remains in force until 16 February 2027. Businesses should therefore be ready to work with the applicable amended position after that transition. What the notification does not say is equally important. It does not expressly state that 17 February 2027 will automatically: invalidate every old test report cancel existing BIS licences make all older stock illegal stop every sale trigger a product recall or create an automatic penalty. Those outcomes should not be added to a compliance article without separate official support. The correct post-transition action will depend on the amended standard and the regulatory framework applicable to the product. Impact on Different Business Teams Stakeholder Main Effect What Should Be Reviewed Smart Meter Manufacturers Need to understand product-level changes Specifications, models, test evidence. Suppliers Customer requirements may change Supply contracts and specifications. Quality Teams Existing evidence may need comparison Test reports and quality documents. Laboratories Testing scope may be affected Actual Amendment No. 4 clauses DISCOMs Procurement documents may need review Tender technical specifications Tender Participants Procurement documents may need review Amendment references in tender Compliance Teams Need to separate standards and certification issues BIS framework and product applicability Legal Teams Contract wording may determine obligations Purchase orders and supply agreements The internal challenge is coordination. A standards amendment can quickly become confusing where sales, quality, engineering and legal teams are working from different versions of the same technical requirement. One controlled internal review is more useful than several departments making separate assumptions. Business Opportunities Created by the Transition A new standards amendment can create demand for technical and compliance support, especially among manufacturers that do not maintain a large standards team in-house. Possible areas of professional support include: amendment impact assessment technical compliance consulting standards gap analysis product-document review laboratory coordination testing assessment conformity-assessment review tender specification review BIS-related compliance support and transition planning. This does not mean the amendment creates guaranteed commercial growth for any service provider. The opportunity depends on how much technical work the actual amendment requires. For manufacturers, the more useful commercial question is whether outside expertise can reduce confusion, avoid unnecessary rework and help different teams work from the same regulatory position. How Corpseed Can Help For a manufacturer, the difficult part is rarely reading the date printed in the Gazette. The harder work begins when that date has to be connected with actual products, test reports, BIS documents, customer contracts and production plans. Corpseed's product compliance services can support businesses that need help assessing how Amendment No. 4 affects their current smart-meter compliance position. Relevant support may include: Applicability review: Checking whether the product and model fall within IS 16444 (Part 1):2015 and whether the amendment is relevant to the business. Amendment impact assessment: Comparing Amendment No. 4 with existing technical specifications once the official amendment is available. Compliance gap assessment: Identifying differences between the amended requirement and current product documentation. BIS compliance review: Examining whether an existing certification or conformity-assessment position requires any action under the applicable official framework. Technical document review: Checking available specifications, quality records, product files and test evidence for consistency. Testing and laboratory coordination: Supporting communication with competent laboratories where the amended clauses create a verified testing need. Tender compliance support: Reviewing smart-meter tender specifications where IS 16444 or its latest amendment is referenced. Ongoing manufacturer compliance support: Tracking applicable regulatory and standards changes that affect product planning. Where BIS certification is actually applicable, Corpseed can also assist businesses in understanding the relevant certification requirements. A BIS certification consultant can help with documentation and process support, but whether a fresh application or additional action is required must first be determined from the applicable official framework. Professional support should make the compliance position clearer. It cannot guarantee BIS approval, a particular laboratory result, tender acceptance, a fixed government timeline or any other regulatory outcome. Smart-meter manufacturers and suppliers preparing for the February 2027 transition can use Corpseed's product compliance services for standards review, compliance gap assessment, technical documentation support and BIS-related regulatory guidance based on their actual product position. Key Takeaways The BIS smart meter amendment 2026 gives manufacturers a clear transition point, but it does not provide the complete technical amendment in the Gazette itself. BIS has established Amendment No. 4 to IS 16444 (Part 1):2015. The standard relates to a.c. Static Direct Connected Watt-hour Smart Meter Class 1 and 2. Amendment No. 4 was established on 17 August 2026. The BIS notification is dated 18 August 2026. The Gazette carrying the notification is dated 25 August 2026. The standard without Amendment No. 4 remains in force until 16 February 2027. The Gazette does not reproduce the detailed technical changes. It does not expressly prescribe a fresh BIS licence, a fresh certification application, automatic retesting, a new fee or a new penalty. Manufacturers should obtain Amendment No. 4 and complete a technical and regulatory impact review before the transition period ends.

Summary: The Bureau of Indian Standards ( BIS ) has notified the establishment of 26 Indian Standards, dated 5 August 2026. Every standard in the schedule was established on 4 August 2026. The notification was published in the Gazette of India, Extraordinary, Part III, Section 4, on 12 August 2026. The BIS 26 Indian Standards 2026 is an update for textiles, ropes, metal tests, fasteners, food oil containers, machinery, mining equipment, aerospace textiles, pollution control, air quality management, and soil samples. Sixteen amended standards have identified prior standards which will coexist till 4 February 2027. Ten items do not identify any prior standard. The notification establishes or amends standards, but it does not, in and of itself, indicate that every item on the list needs BIS certification or requires the Standard Mark. Companies need to verify if there is a Quality Control Order (QCO), regulation, licensing condition, tender, or contract that mandates any particular standard. Notification at a Glance Particular Verified details Issuing authority Bureau of Indian Standards, Department of Consumer Affairs Governing law Rule 15(1), Bureau of Indian Standards Rules, 2018; read in the wider framework of the BIS Act, 2016 Sectors covered Textiles, ropes, metals, mechanical components, food packaging, pollution control, machinery safety, mining, aerospace, air quality and soil quality Main stakeholders Manufacturers, standard users, BIS licensees where applicable, laboratories, engineers, consultants, purchasers and tendering authorities Core development 26 standards established: 16 revised/replacement standards and 10 entries with no predecessor listed Transition/withdrawal date 4 February 2027 for the 16 identified predecessor standards Universal certification deadline Not expressly specified Nature of requirement Establishment and withdrawal of Indian Standards; mandatory certification is not created expressly by this notification alone The Regulatory Framework BIS is India’s national standards body. Section 10 of the Bureau of Indian Standards Act, 2016 authorizes the Bureau to establish, publish, review, promote, and adopt Indian Standards. Section 10(4) states that an Indian Standard is notified and remains valid until BIS withdraws it. This notification is made under Rule 15(1) of the Bureau of Indian Standards Rules, 2018. The purpose of this notification is to establish the standard as mentioned in the schedule and, if there is any previous version of the standard, its date of withdrawal. Standardization and compulsory certification are related but different legal steps. Section 16 of the BIS Act allows the Central Government to direct the compulsory use of a Standard Mark in specified circumstances. BIS guidance on QCOs also explains that its certification scheme is generally voluntary, while the Central Government can make conformity and use of the Standard Mark compulsory for specified products through a QCO. The legal impact of such notification in the Gazette needs to be studied. It provides the relevant Indian Standards and also the deadlines for transitioning. All mandatory requirements related to manufacture, import, sale, testing, marking, or certification shall be supported by a particular QCO or any other binding instrument. What Has Changed in BIS 26 Indian Standards 2026 BIS has established 26 standards, effective from the date shown in the schedule: 4 August 2026. The changes fall into two groups. Sixteen revised or replacement standards: Entries 2 to 17 identify an earlier standard. Both editions remain in force concurrently until the predecessor is withdrawn on 4 February 2027. Ten standards with no predecessor listed: Entries 1 and 18 to 26 show “NA” for the standard to be withdrawn and the withdrawal date. Several ISO-aligned standards: The schedule identifies ISO or ISO/TS references for metallic tensile testing, grooved pins, machinery safety, rope testing, and soil sampling. Several environmental standards: The notification includes revisions for industrial pollution control and new standards on air-quality planning, plastic-waste pyrolysis, ambient-air assessment, and soil investigations. No detailed technical clauses in the Gazette: The schedule gives standard numbers, titles, and dates. It does not reproduce design values, test parameters, sampling rules, certification procedures, fees, or marking conditions.

The table does not mean that all 26 standards apply to every business, nor that each subject is subject to compulsory certification. Revised Standards and Their Withdrawal Dates Entries 2 through 17 are now replacing the editions that preceded them. The previous editions will continue to operate concurrently and will be withdrawn on 4 February 2027. Transition event Date Entries affected Meaning Revised standards established 4 August 2026 2-17 The 2026 editions became established Indian Standards Notification dated 5 August 2026 All 26 Date printed on the BIS notification Gazette publication 12 August 2026 All 26 Date of publication in the Gazette of India Earlier editions withdrawn 4 February 2027 2-17 Listed predecessor editions cease to remain in force after concurrent operation However, the notification does not establish 4 February 2027 as a universal deadline for production, distribution, and certification. In cases where a new standard has a QCO or a BIS license, the changeover requirements must be verified. New Standards With No Previous Version Ten entries show “NA” in both predecessor and withdrawal columns: IS 1608 (Part 5): 2026 for tensile testing of miniaturized metallic test pieces. IS 19763: 2026 for aircraft woven carpet. IS 19783: 2026 for 100 percent nylon woven fabric. IS 19822: 2026 for measuring electrostatic surface potential of fiber ropes. IS 19879: 2026 for preparing an air-quality management plan. IS 19880: 2026 for controlling air pollution from plastic-waste pyrolysis. IS 19881: 2026 for assessing ambient-air assimilative and carrying capacity. IS 19882 (Parts 1, 2 and 3): 2026 for different soil-quality investigation settings. “NA” means that this schedule does not identify an earlier Indian Standard for withdrawal. It should not be read as proof that the activity was previously unregulated, that another standard never applied, or that the new standard is compulsory in every situation. Concurrent Validity of Old and New Standards However, the notification clearly allows both the old and the revised editions of items 2 to 17 to coexist until 4 February 2027. This provides sufficient time for general users to evaluate the revised edition. However, simultaneous validity does not imply that the organization can use either edition for any given application. QCO, the BIS Product Manual, the Certification Direction, the customer specification, the tender, or a contractual agreement will specify the particular edition to be used. In case of manufacturing under a BIS License, manufacturers are advised to check their scheme-specific position before using the Gazette Schedule. Internal management should make sure that each department uses the correct edition when preparing drawings, test plans, quality manuals, purchase specifications, and customer commitments. Industry-Wise Classification of the Standards Sector Relevant standards Main subject Textiles, ropes and sewing equipment IS 3256, IS 5175, IS 9874, IS 11916, IS 13872, IS 19763, IS 19783, IS 19822 Packaging and testing of ropes, sewing-machine components, aerospace yarn and carpet, nylon fabric Metals, lifting and mechanical components IS 1608 (Part 5), IS 7385, IS 8324 Tensile testing, grooved pins, lifting chains and chain slings Food and edible-oil packaging IS 10325 Square tins of 15 kg or 15 litre capacity Iron, steel, refractories and aluminium IS 10447, IS 11304, IS 12112, IS 12185 Solid-waste management and air-pollution control Mining and machinery safety IS 13618, IS 16810 (Part 1), IS 16815 Mine haulages, safety-related control systems and safeguard positioning Coastal and environmental management IS 7967, IS 19879, IS 19880, IS 19881 Coastal outfalls, air-quality planning, plastic pyrolysis and ambient-air assessment Soil investigation IS 19882 (Parts 1-3) Preliminary, contaminated-site and natural/agricultural-site investigations Several standards have cross-sector use. Machinery safety standards may matter to equipment designers and manufacturers across many industries. In contrast, air- and soil-quality standards may be relevant to consultants, laboratories, project developers, and regulators across multiple product categories. Which Standards Affect Your Business? Business or stakeholder Potentially relevant standards Why they may matter Verification needed Rope manufacturers and users IS 3256, IS 5175, IS 19822 Packaging, product specification and electrostatic-potential testing Product scope, contract and any certification requirement Sewing-machine manufacturers IS 9874, IS 13872 Arm, bed and stitch-regulator specifications Product design references and buyer requirements Food-tin manufacturers and edible-oil packers IS 10325 Specification for 15 kg/15 litre square tins Packaging contracts and applicable food/product rules Steel, refractory and aluminium plants IS 10447, IS 11304, IS 12112, IS 12185 Waste-management and air-pollution practices Environmental consent conditions and regulatory references Machinery designers and system integrators IS 16810 (Part 1), IS 16815 Safety-related control-system design and safeguard positioning Design scope, tender and machine-safety obligations Mines and mining-equipment suppliers IS 13618 Direct-rope mine haulages from 50 kW to 150 kW Mine-safety rules, approvals and procurement specifications Aerospace textile suppliers IS 11916, IS 19763 Glass yarn and aircraft woven carpet Customer, aviation and quality-system specifications Environmental consultants and laboratories IS 7967, IS 19879-19882 Air, coastal-outfall and soil investigation methods Terms of reference, consent conditions and laboratory competence Importers and exporters Any product-specific entry Buyer or Indian regulatory specifications may cite an edition QCO, customs/product law and destination-market requirements This is an applicability screen, not a legal determination. Product classification, intended use, contract language, and separate regulatory instruments can change the result. Does This Notification Make BIS Certification Mandatory? No. The notification does not expressly make BIS certification mandatory for all 26 standards. It establishes the standards and sets withdrawal dates for identified earlier editions. BIS certification becomes compulsory for specified products when a legally applicable instrument, commonly a QCO issued by the relevant Central Government ministry or department, requires conformity to an Indian Standard and use of the Standard Mark under a BIS license or certificate of conformity. Other laws, regulations, or license conditions may also incorporate a standard. The correct check has three parts: Identify the exact product, process, or activity and the corresponding Indian Standard. Search for an applicable QCO or other binding instrument and confirm its commencement date, scope, and exemptions. If a BIS license already exists, check the product manual and the BIS transition direction for the revised edition. The Gazette schedule contains no provisions for universal application procedures, testing frequency, license fees, Standard Mark direction, penalties, or enforcement dates. Adding any of those requirements to this notification without another verified legal source would overstate its effect. Difference Between Establishment and Mandatory Compliance Concept Meaning Position in this notification Establishment of an Indian Standard BIS formally recognises the standard under the BIS framework Expressly stated for 26 standards Establishment of an Indian Standard The predecessor ceases to remain a current Indian Standard on the stated date Expressly stated for 26 standards Voluntary conformity assessment A person may seek certification where the relevant scheme permits Not created or detailed here Mandatory conformity A binding instrument requires compliance with a specified standard Not imposed universally by this notification Standard Mark Mark representing conformity under a BIS scheme No new universal marking direction stated here Contractual compliance A buyer, tender or contract requires a particular edition Possible business effect, but contract-specific The institution serves as the acknowledged technical standard. Compulsory compliance is based upon a distinct legal trigger. Adoption through contracts may also be obligatory for the parties, even in the absence of a statutory obligation, because of this notification. Implementation Schedule and Standards Date Event Affected parties Appropriate action 4 August 2026 All 26 standards established Users of the listed standards Identify relevant new editions 5 August 2026 Notification dated Regulated and interested stakeholders Record the formal notification reference 12 August 2026 Gazette publication All stakeholders Begin documented applicability and transition review Up to 4 February 2027 Gazette publication Users of revised standards Compare editions and confirm required version 4 February 2027 Listed predecessor standards withdrawn Users of entries 2-17 Complete changeover where applicable The source does not mention phase dates by sector, exemptions for MSMEs, certificate conversion periods, testing deadlines, or inventory waivers. These will need independent verification wherever applicable. Actions for Existing Users of the Standards Organizations employing any of the standards in the preceding versions, as indicated by entries 2 to 17, should focus on a controlled transition review. Map all occurrences. Find out the standard number and revision in drawings, bill of materials, test plan, quality manual, work instruction, contract, purchase order, and tender. Get the complete revised standard. It is insufficient to rely on just the title from the Gazette for clause-by-clause comparison. Compare the new edition against the prior edition. Identify the legal trigger. Is there a QCO, regulation, condition, license, approval, tender, or customer requirement requiring compliance with the standard or its latest revision. Consider technical inadequacies. Analyze the changes made to the scope, definitions, materials, dimensions, performance, safety, sampling, testing, packaging, labelling, and record-keeping requirements throughout the standard. Arrange testing. Ensure that internal or external labs can test according to the standard revision and that the scope is appropriate for the work. Control the change. Allocate the owners, approval date, and document revisions. Do not allow different groups to use conflicting versions inadvertently. Maintain proof. Preserve the applicability analysis, comparative data, approvals, revised specification, and stakeholder communications for suggested internal controls. These are practical recommendations. The notification itself does not prescribe this seven-step process. Impact on Manufacturers, Importers, Laboratories and Buyers The updated Indian Standards may affect product design, testing, documents, purchasing and supply agreements. The actual impact depends on whether a particular standard applies through a law, Quality Control Order (QCO), BIS license, tender, or contract. 1. Impact on Manufacturers Check whether any new or revised standard covers their products. Compare the earlier standard with the 2026 version. Review product designs, materials, and production processes. Update quality manuals, drawings, and test plans where required. Complete the transition before the earlier standard is withdrawn, if applicable. 2. Impact on Importers Confirm that any applicable standards cover the products imported. Determine whether the QCO requires BIS certification to be compulsory. Seek information from foreign suppliers regarding the latest test reports and certificates. Ensure that marking and certificate pertain to the right standard. Review the import documents before ordering fresh products. 3. Impact on Testing Laboratories Obtain and study the relevant 2026 testing requirements. Check whether existing equipment can perform the required tests. Train testing staff on revised methods where needed. Update testing procedures, report formats, and internal records. Confirm whether the scope of recognition or accreditation needs to be updated. 4. Impact on Buyers and Procurement Teams Review the purchase order, tender documents, and product specification. Specify the relevant standard number and year in new documents. Decide which edition of the standard document is valid in the transition period. Seek the required test results or certificate from suppliers. 5. Impact on Existing BIS License Holders Check whether the licensed product is related to the standard. Refer to BIS guidance in transitioning to the 2026 version. Establish new testing or documentation that needs to be completed. Provide information within the appropriate timeframe. Do not take for granted that the change in the Gazette automatically amends the license. 6. Impact on Suppliers and Distributors Identify the proper version needed by the manufacturer and purchaser. Revise descriptions and technical documents when required. Don’t make unsubstantiated claims regarding BIS certification. Maintain records received from manufacturers and laboratories. Inform buyers about relevant standard-version changes. 7. Impact on MSMEs Identify only the standards connected with their products or activities. Estimate possible testing, documentation, and process-update costs. Plan the changeover process well in advance to avoid hasty modifications. Obtain technical assistance when internal resources are inadequate for this. Never presume that there is a specific MSME exception unless explicitly mentioned. This notice does not make every item mentioned in it mandatory. Every firm must determine whether a particular QCO/BIS certificate/license requirement/tender contract applies to it. Stakeholder Immediate impact Possible operational or cost effect Priority concern Manufacturers Identify relevant revised standards Technical review, testing, or document updates Required edition and changeover date Importers Check product coverage Supplier evidence and certification review Applicable QCO or other law Laboratories Review new test work Method capability and scope updates Competence for the 2026 edition Buyers/tender authorities Update specifications where needed Contract and vendor communication Avoid ambiguous edition references Environmental teams Review revised/new codes and methods Plans, studies, or consultant scope Whether permits or terms incorporate the standard Document Limitations and Matters Requiring Separate Verification The notification is a schedule of standards and dates. It does not reproduce the standards or answer every implementation question. Clause-level differences between old and new editions are not stated. Mandatory certification status for each listed product is not stated. Product-specific QCO coverage and commencement dates are not listed. Application procedures, license conditions, fees, and testing frequency are not stated. Action on existing certificates, test reports, contracts, labels, and inventories is not specified in this notification. No penalties or enforcement actions are mentioned in this notification. No exemptions for MSMEs, exports, or research purposes are mentioned. While the notification was dated 5 August 2026 by the authority, each scheduled standard has an establishment date of 4 August 2026. Both dates appear in the Gazette and should not be conflated. The full official standard and any applicable QCO, product manual, license direction, regulation, tender, or contract must be checked before a business makes a compliance decision. What Businesses Should Do Next Priority Action Responsible team Relevant date Expected outcome 1 Screen all 26 entries against products, operations, and contracts Compliance/legal with engineering Immediate Relevant standards identified 2 Check applicable QCOs and other binding instruments Regulatory/legal Immediate Mandatory status confirmed or ruled out 3 Obtain and compare relevant 2026 standards Engineering, quality and EHS Before transition planning Technical gaps documented 4 Confirm laboratory and supplier readiness Quality/procurement During concurrent period Testing and supply risks identified 5 Update controlled documents and contracts where required Quality, engineering and commercial Before 4 February 2027 for revised entries, where applicable Consistent edition use 6 Confirm scheme-specific changeover with BIS or the regulator License holder/compliance Before relying on an edition choice Written implementation position Companies that do not come across any relevant standard must keep a short applicability file. Companies that identify a relevant standard but not a compulsory tool must consider business-related reasons for adopting the standard voluntarily. How Can Corpseed Help? Corpseed helps manufacturers, importers, suppliers, and other businesses understand how the updated BIS standards may affect them. The support depends on the product, the applicable Indian Standard, and the relevant Quality Control Order (QCO). 1. Checking Which Standard Applies Review the business’s products and activities. Identify the relevant Indian Standard. Explain whether the updated standard affects the business. 2. Checking Whether BIS Certification Is Required Determine whether the QCO covers the good. Determine whether BIS certification is compulsory or voluntary. Determine the relevant dates, conditions, and exemptions. 3. Comparing Previous and Current Standards Comparison between the previous standard and the 2026 standard. Identify important technical or document changes. Prepare a simple plan for moving to the new standard. 4. BIS Certification Support Help prepare the BIS certification application. Help with document gathering and validation. Facilitate communication and follow-ups during the application process. The certification is still dependent on approval by BIS and the applicable scheme. 5. Document Review and Updates Review product specifications, drawings, and quality documents. Check whether documents mention the correct standard. Help update test plans, purchase orders, and supplier documents. 6. Product Testing Support Identify the tests required under the applicable standard. Help coordinate testing with a suitable laboratory. Check test reports and related documents for completeness. Testing results and laboratory acceptance depend on the applicable standard and certification scheme. 7. Compliance Support for Businesses Help manufacturers prepare for the revised standards. Assist importers in checking product and supplier documents. Support suppliers with tender and contract requirements. Help businesses maintain proper compliance records. Corpseed provides regulatory, documentation, and coordination support. BIS certification, approval, testing, and timelines depend on the competent authority, applicable scheme, and completeness of the application. Businesses can consult a BIS certification consultant to determine which standard applies and what certification, testing, or transition actions may be needed.

Subject

Summary: The Bureau of Indian Standards ( BIS ) has amended three Indian Standards covering shuttering plywood, hearing protectors and stainless steel sinks for domestic use. The affected standards are IS 4990:2024, IS 9167:2025 and IS 13983:1994. The amendments were established on 3 August 2026. The notification is dated 5 August 2026, and was published in the Gazette of India on 12 August 2026 under reference HQ-PUB015/1/2020-PUB-BIS (1585). The earlier versions of the three standards will continue to apply until 2 February 2027. This transition period is important for manufacturers, licence holders, testing teams, buyers, and suppliers dealing with these products. They should review the amendments and check whether the changes affect their product specifications, testing, quality checks or related documents. The notice establishes the amendments and the concurrent-validity dates. It does not reproduce the amended clauses or introduce a standalone certification process, fee, testing method or penalty. Notification at a Glance Particular Verified Details Issuing authority Bureau of Indian Standards, Department of Consumer Affairs Document type BIS notification establishing amendments to Indian Standards Reference number HQ-PUB015/1/2020-PUB-BIS (1585) Notification date 5 August 2026 Gazette publication date 12 August 2026 Date of establishment of amendments 3 August 2026 Governing provision Rule 15(1) of the Bureau of Indian Standards Rules, 2018 Standards covered IS 4990:2024, IS 9167:2025 and IS 13983:1994 Main stakeholders IS 4990:2024, IS 9167:2025 and IS 13983:1994 Core development BIS established one amendment for each of IS 4990 and IS 9167, and Amendment No. 4 for IS 13983 Transition end date 2 February 2027 Effective date The amendments were established on 3 August 2026; a separate commencement date is not expressly specified Nature of requirement Standards notification; the detailed technical changes are not reproduced in the Gazette notice The dates have different functions. The amendments were established on 3 August, the notification bears the date 5 August and the Gazette was published on 12 August 2026. The unamended standards may remain in force only up to 2 February 2027, as stated in the schedule. The Regulatory Framework BIS issued the notification under Rule 15(1) of the Bureau of Indian Standards Rules, 2018. Rule 15 deals with the establishment, review, revision and amendment of Indian Standards. It provides the mechanism through which BIS may establish an amendment and notify the period for which an existing standard may continue alongside the amended position. This notification performs that standards-management function. It identifies the affected Indian Standards, the number and month of each amendment, the date on which each amendment was established and the date until which the standard without that amendment may remain in force. An Indian Standard notification should not automatically be treated as a new Quality Control Order or a fresh certification mandate. Whether a product must carry the Standard Mark or operate under BIS certification depends on the applicable governing law, Quality Control Order, certification scheme and other official directions. Those questions must be assessed separately for each product and business. Scope and Applicability The notification applies only to the three standards specifically mentioned in it and the amendments made to those standards. It should not be read as a wider change covering all types of plywood, hearing protection products, or stainless steel products. Businesses should check whether their particular product falls under any of the three standards before making changes to their compliance process. Product or Standard Covered by This Notice? Relevant Condition Main Review Area Plywood for concrete shuttering works under IS 4990:2024 Yes Amendment No. 1, August 2026 Technical specification, product testing, declarations and marking should be checked against the amendment text Hearing protectors under IS 9167:2025 Yes Amendment No. 1, August 2026 Product and test requirements should be checked against the amendment text Stainless steel sinks for domestic purposes under IS 13983:1994 Yes Amendment No. 4, August 2026 Material, construction, performance and marking provisions should be checked against the amendment text Products outside these three standards No direct coverage stated No amendment is announced for them in this notice Check their own applicable standards and regulatory instruments The notice does not list exemptions, business-size relaxations or separate dates for domestic manufacturers, foreign manufacturers, importers or micro, small and medium enterprises (MSMEs). What Has Changed BIS has established one identified amendment for each of the three standards. The Gazette does not show the clause-level changes, so the precise earlier and new technical positions cannot be compared from this notice alone. Compliance Area Earlier Position New Position Relevant Date Business Meaning IS 4990:2024 Standard operated without Amendment No. 1 Amendment No. 1, August 2026, has been established 3 August 2026 Obtain the amendment and review its effect on applicable plywood specifications and compliance evidence IS 9167:2025 Standard operated without Amendment No. 1 Amendment No. 1, August 2026, has been established 3 August 2026 Review the amendment before making technical, testing or product-control changes IS 13983:1994 Standard included amendments preceding Amendment No. 4 Amendment No. 4, August 2026, has been established 3 August 2026 Review the amendment before making technical, testing or product-control changes Concurrent validity Unamended versions continued to apply Standards without the listed amendments may remain in force until 2 February 2027 Up to 2 February 2027 Plan implementation within the stated transition window The notification establishes a common transition date for all three standards. It does not state that every affected business must complete an identical process, because the necessary action will depend on the amendment text and the entity's certification or commercial position. Product-Wise Analysis of the BIS Amendments 2026 IS 4990:2024 - Plywood for Concrete Shuttering Works BIS has established Amendment No. 1 of August 2026 to IS 4990:2024, Plywood for Concrete Shuttering Works - Specification (Fourth Revision). The amendment was established on 3 August 2026. IS 4990:2024 without Amendment No. 1 may remain in force until 2 February 2027. BIS material describing IS 4990:2024 states that the standard covers plywood used for shuttering and formwork in construction. It identifies plain, polymer-coated and film-faced types, as well as E1 and E2 formaldehyde classifications. The standard addresses matters such as raw materials, dimensions, workmanship, water resistance, strength, preservative retention and formaldehyde-related testing. That background explains why a technical review may affect product manuals, test facilities, test reports, specifications, declarations or marking. However, the August 2026 Gazette notice does not say which of those areas Amendment No. 1 changes. Businesses should not reuse the change list from the original 2024 revision as though it describes the 2026 amendment. IS 9167:2025 - Hearing Protectors BIS has established Amendment No. 1 of August 2026 to IS 9167:2025, Hearing Protectors - Specification (First Revision). The date of establishment is 3 August 2026, while the standard without the amendment may remain in force until 2 February 2027. The product title indicates that the standard concerns hearing protectors. The notification does not identify particular device types, performance values, attenuation requirements, test methods, markings or user-information changes. Manufacturers and laboratories therefore need the official Amendment No. 1 text before modifying product specifications or testing programmes. The notice also does not state that the amendment creates a new legal duty to obtain BIS certification. Any certification or market-access conclusion must be based on the separate legal instrument applicable to the product. IS 13983:1994 - Stainless Steel Sinks for Domestic Purposes BIS has established Amendment No. 4 of August 2026 to IS 13983:1994, Stainless Steel Sinks for Domestic Purposes - Specification. The amendment was established on 3 August 2026. The standard without Amendment No. 4 may remain in force until 2 February 2027. The standard is confined by its title to stainless steel sinks intended for domestic purposes. The Gazette notice does not extend the amendment to all stainless steel products or every type of commercial sink. It also does not reproduce changes concerning steel grade, thickness, dimensions, workmanship, corrosion performance, fitting features, marking or tests. BIS has earlier listed IS 13983:1994 in its consumer information on mandatory certification for certain cookware, utensils, and cans. However, businesses should refer to the current Quality Control Order, and relevant BIS certification requirements to confirm whether certification applies. The August 2026 standards notification itself should not be treated as the basis for that requirement. Implementation Timeline and Concurrent Validity All three amendments follow the same schedule. Event Date Affected Stakeholders Practical Action Amendments established by BIS 3 August 2026 Businesses and technical teams using the three standards Obtain the amendment texts and begin impact assessment BIS notification dated 5 August 2026 Regulatory, legal and compliance teams Record the official reference and scope Gazette publication 12 August 2026 All relevant stakeholders Treat the notice as officially published and plan within the transition window Last date on which the standards without the listed amendments may remain in force 2 February 2027 Users of the unamended standards Complete the applicable technical and documentary transition before the old position ceases to remain in force The Gazette does not call 2 February 2027 a general licence-renewal or certification deadline. It is the date until which each standard without the specified amendment may remain in force. The effect on an individual licence, pending application, product test report or production batch must be confirmed under the applicable BIS implementation directions. Information Not Expressly Specified The short Gazette notification does not provide the substantive contents of the three amendments. It also does not expressly specify: The clauses, tables, annexures or test methods changed by each amendment Revised technical values, tolerances, performance criteria or sampling plans Product-marking, packaging or labelling changes A separate date on which each new technical clause becomes compulsory, apart from the establishment and concurrent-validity dates stated Procedures for existing BIS licence holders or pending applicants Retesting, factory inspection, surveillance or audit requirements Forms, declarations, reports or records to be submitted Fees, deposits or other financial amounts Exemptions or special treatment for MSMEs, startups, importers or foreign manufacturers Penalties or enforcement consequences Treatment of stock manufactured, imported, contracted or tested before the transition ends These omissions do not mean that no connected requirements exist. They mean those requirements cannot be derived from this notification and must be checked in the actual amendments, applicable certification scheme, Quality Control Order, product manual and implementation guidelines. Separate Documents Businesses Must Consult Implementation requires more than the two-page Gazette notice. Document Status in the Supplied Source Why It Is Needed Amendment No. 1, August 2026, to IS 4990:2024 Identified but not reproduced Reveals the clause-level technical change for shuttering plywood Amendment No. 1, August 2026, to IS 9167:2025 Identified but not reproduced Reveals the revised requirements for hearing protectors Amendment No. 4, August 2026, to IS 13983:1994 Identified but not reproduced Reveals the revised requirements for domestic stainless steel sinks Current product manual and scheme of inspection and testing, where applicable Not identified in the Gazette May govern testing, marking and licence controls Product-specific BIS implementation guidelines Not identified in the Gazette May explain transition treatment for licensees and applicants Current Quality Control Order or other mandatory instrument, where applicable Not identified in the Gazette Determines whether compliance or certification is legally compulsory for a given product and entity Only current official versions should be used. Internal specifications and supplier contracts may then be checked against the verified legal and technical position. Impact on Businesses The immediate effect is a need for targeted review rather than an assumption that every process has changed. The level of work will depend on the actual amendment and the stakeholder's role. Manufacturers and Existing Licence Holders Manufacturers using any of the three standards should identify affected products and obtain the amendment text. Existing licence holders may need to compare their product design, raw materials, manufacturing controls, test facilities, marking, declarations and records with the amended clauses. Any licence-specific action should follow official BIS directions rather than a generic process. Applicants and Product-Development Teams Pending applicants and businesses developing products against these standards should confirm which version BIS will accept at each stage. Technical files, drawings, bills of material, inspection plans, and laboratory instructions may need revision if the amendment changes a relevant clause. Laboratories and Quality Teams Do not change a testing method just because a new amendment has been issued. First check the actual changes in the standard. There may be changes to equipment, samples, test conditions, calculations, acceptance limits, or test reports. Keep a clear record of which version was followed. Importers, Buyers and Supply Chain Partners There is no direct requirement for importers, distributors, or buyers in this notification. However, they should check the standard version mentioned in product documents, certificates, test reports and purchase orders. For orders that will continue after the transition period, the technical details may need to be reviewed and updated. Stakeholder Immediate Impact Likely Operational Effect Priority Concern Manufacturer Amendment impact review Possible updates to product controls and technical evidence Obtain official amendment text Existing licence holder Check BIS transition directions Possible licence-scope or evidence update Confirm action with the relevant BIS office or official guideline Applicant Verify acceptable standard version Possible change to application or test evidence Avoid relying on an obsolete version after transition Laboratory Review technical changes Possible method, equipment or report update Do not infer tests from the notice alone Buyer or importer Review specifications and supplier evidence Contract and procurement updates may be needed Align orders scheduled after 2 February 2027 Risks and Practical Considerations No fine, prosecution, cancellation, recall or seizure is stated in this notification. It would therefore be inaccurate to assign a statutory penalty to the notice itself. The risks mainly arise when businesses fail to address the changes within the required period. These may include reliance on an outdated technical reference, incomplete test records, differences in supplier specifications, delayed updates or product documents that do not match the revised standard. Where a separate mandatory certification requirement applies, failure to follow the revised requirements may also affect the certification process. The exact impact will depend on the applicable certification scheme, and should be confirmed from the relevant BIS requirements. Businesses should also avoid assuming that the same action applies to all three products. Each amendment may address different technical subjects. What Businesses Should Do Next Confirm product coverage. Map products and models against the exact titles and numbers of IS 4990:2024, IS 9167:2025 and IS 13983:1994. Obtain the official amendments. Secure the three August 2026 amendment texts from BIS. Do not rely on the Gazette schedule as a substitute for their technical content. Compare affected clauses. Create a controlled comparison of the current requirement, amended requirement, evidence of conformity and responsible department. Check certification status separately. Determine whether a current Quality Control Order, BIS certification scheme, product manual or licence condition applies to the specific product and business. Review implementation directions. Look for product-specific BIS guidelines covering existing licences, applications, testing, endorsements, surveillance or scope changes. Update internal and commercial documents. Where the amendment requires it, revise specifications, drawings, inspection plans, test instructions, supplier requirements, purchase orders, labels and records. Plan ahead of 2 February 2027. Use the transition period to review the changes and complete any required updates before the older standards are withdrawn. Keep clear records of the standard and amendment version followed. Seek clarification when needed. If any technical or licensing requirement is unclear, check with BIS or a qualified professional. Do not make compliance decisions based on assumptions. How Corpseed Can Help? Corpseed can support manufacturers, applicants, importers and other affected businesses in converting the notification into a product-specific action plan. A BIS certification consultant can help distinguish the amendment notice from separate mandatory certification requirements and identify the official documents that control implementation. Relevant support may include: Product and standard applicability assessment Retrieval and review of applicable BIS amendments and official directions Clause-level compliance gap assessment Review of current Quality Control Orders and certification status BIS application and licence-support documentation, where required Technical-file, test-report and product-manual review Coordination support for recognised laboratory testing, where applicable Transition planning for existing licences and pending applications Corpseed's role is to organise the applicable requirements, documentation and stakeholder actions. Certification, approval and timelines remain subject to the governing rules, technical conformity and decisions of the competent authority. Businesses dealing with shuttering plywood, hearing protectors or domestic stainless steel sinks may contact Corpseed for document-specific BIS certification services and technical compliance consulting before the 2 February 2027 transition date. Key Takeaways The BIS 2026 notification updates three Indian Standards and gives businesses time to move from the older versions to the amended ones. However, the notification does not explain the changes in detail. Businesses should read the official amendment documents, and check any product-specific requirements before making changes to their testing, product specifications, or certification processes. Amendment No. 1 applies to IS 4990:2024 for plywood used in concrete shuttering works. Amendment No. 1 applies to IS 9167:2025 for hearing protectors. Amendment No. 4 applies to IS 13983:1994 for domestic stainless steel sinks. All three amendments were established on 3 August 2026. The standards without the listed amendments may remain in force until 2 February 2027. The notice does not state technical changes, fees, procedures, exemptions or penalties. Product-specific certification and implementation duties must be verified separately.

Subject

Summary: The BIS Indian Standards notification 2026 has established nine standards through Ref. HQ-PUB013/1/2020-PUB-BIS (1583), dated 5 August 2026 and published in the Gazette of India on 12 August 2026. All nine standards have an establishment date of 3 August 2026. They cover industrial chemicals, chemical-safety codes, animal-feed material, homoeopathic preparations, traditional medicine and the safe handling of biotherapeutic products. Four are revised standards. Their earlier versions remain in force concurrently until 3 February 2027 and are scheduled to be withdrawn on that date. The remaining five entries have no earlier standard identified in the notification. Manufacturers, laboratories, procurement teams, product developers, safety professionals and businesses using these standards should review the correct 2026 edition. The notification establishes and transitions standards, it does not, by itself, state that BIS certification , registration, testing or licensing is mandatory for the listed products. Notification at a Glance Particular Verified details Issuing authority Bureau of Indian Standards, Department of Consumer Affairs Document type Gazette notification establishing and revising Indian Standards Reference number HQ-PUB013/1/2020-PUB-BIS (1583) Gazette identifier CG-DL-E-12082026-275420, Gazette No. 497 Notification date 5 August 2026 Gazette publication date 12 August 2026 Date of establishment 3 August 2026 for all nine standards Separate effective date Not expressly specified, the schedule gives 3 August 2026 as the establishment date Governing provision cited Rule 15(1) of the Bureau of Indian Standards Rules, 2018 Sectors covered Industrial chemicals, chemical safety, animal feed, homoeopathy and traditional medicine Main stakeholders Manufacturers, users, laboratories, procurement and quality teams, product developers and standard users Core development Nine standards established: four revisions and five entries with no predecessor listed Transition deadline 3 February 2027 for withdrawal of the four identified older standards Nature of requirement Establishment, revision, concurrent running and scheduled withdrawal of standards, no certification mandate is stated in this notification The date sequence matters. The standards were established on 3 August, the notification is dated 5 August, and the Gazette published it on 12 August 2026. Businesses should not describe the publication date as the establishment date. The Regulatory Framework The Bureau of Indian Standards (BIS) is India’s national standards body and functions under the Bureau of Indian Standards Act, 2016. The notification refers to Rule 15(1), of the Bureau of Indian Standards Rules, 2018, which allows BIS to establish, reaffirm, amend, revise or withdraw Indian Standards after consulting the relevant stakeholders. Under Rule 15(2) these changes are formally notified through the Official Gazette. The wider Rules also distinguish a standard from a compulsory legal requirement. Rule 24 states that Indian Standards are generally voluntary and become binding when a contract stipulates them, legislation refers to them, or a specific government order makes them mandatory. BIS similarly explains that compulsory use of the Standard Mark for covered products is directed through Quality Control Orders (QCOs). This means businesses must complete a second-level applicability check. A standard appearing in this notification is established and available for adoption, but mandatory certification cannot be inferred from this document alone. A relevant QCO, sectoral law, licence condition, procurement specification, contract or other binding instrument may still require compliance in a particular case. Scope and Applicability The notification relates to nine specifically mentioned standards instead of one comprehensive compliance system for the entire industry. The immediate issue that the notification deals with is the setting up of the standards specified and, in case of four standards, their coexistence with earlier versions followed by their withdrawal. Stakeholder or Activity Connection with the Notification Main Review Point Chemical manufacturers and users p-Toluidine, o-Toluidine, chlorosulphonic acid and hexane Identify the applicable specification or safety-code edition Animal-feed manufacturers and suppliers Monocalcium phosphate, animal feed grade Review IS 19887:2026 and any separate feed-law or contractual requirements Homoeopathic product manufacturers and laboratories Mother tinctures, Echinacea extract and biotherapeutic products Review the applicable test, specification or handling standard Traditional-medicine product businesses Echinacea angustifolia whole plant Review IS 19900:2026 where relevant to material specifications or procurement Testing laboratories Test methods and specifications may affect methods, scope and customer requirements Obtain the complete standard before changing a method or report format Procurement and contract teams Standards may be incorporated into tenders or supply agreements Verify the edition and transition language used in each contract Existing BIS licensees or applicants A revised standard may affect certification documentation if a scheme or licence covers it Check product-specific BIS directions separately, this notice gives no certification process The Gazette does not reproduce the technical clauses of the nine standards. It therefore does not provide product grades, sampling rules, test values, marking requirements, packaging conditions, laboratory methods or acceptance criteria. Those details must be taken from the official text of each relevant Indian Standard and any separately applicable legal instrument. What the BIS Indian Standards Notification 2026 Has Changed The latest BIS notification covers nine standards established in 2026, all carrying the same establishment date. Of these, four are revised versions of existing standards and will run alongside the older editions for six months before those editions are withdrawn. The other five are new standards, with no earlier versions listed for withdrawal. IS 5647 has moved from the 2003 first revision to the 2026 second revision. IS 5649 has moved from the 2003 second revision to the 2026 third revision. IS 6156 has received its first revision, replacing the 1971 code after the transition. IS 10870 has received its first revision, replacing the 1984 code after the transition. Five standards numbered IS 19887, IS 19897, IS 19898, IS 19900 and IS 19901 have been established without a predecessor identified in the schedule. Compliance Area Earlier Position Identified in the Notification New Position Relevant Date Business Meaning p-Toluidine specification IS 5647:2003, first revision IS 5647:2026, second revision New edition established 3 August 2026, old edition withdrawn 3 February 2027 Specifications and documents referencing the old edition should be reviewed o-Toluidine specification IS 5649:2003, second revision IS 5649:2026, third revision Same transition dates Quality, supply and testing references may need edition control Chlorosulphonic acid safety code IS 6156:1971 IS 5649:2026, third revision Same transition dates Safety systems should be compared with the revised code Hexane safety code IS 10870:1984 IS 10870:2026, first revision Same transition dates Handling and safety documentation should be checked against the new edition Five additional subjects No predecessor listed Five 2026 standards established 3 August 2026 Businesses should assess whether a newly available standard is relevant to products, tests or handling practices The notification does not provide a clause-by-clause comparison. Any statement about changed limits, test methods or safety controls would require the full earlier and 2026 standard texts. Nine Indian Standards Established by BIS S. No. 2026 Indian Standard Subject Status shown in notification 1 IS 5647:2026 p-Toluidine- Specification (Second Revision) Revises IS 5647:2003 2 IS 5649:2026 o-Toluidine- Specification (Third Revision) Revises IS 5649:2003 3 IS 6156:2026 Chlorosulphonic Acid- Code of Safety (First Revision) Revises IS 6156:1971 4 IS 10870:2026 Hexane- Code of Safety (First Revision) Revises IS 10870:1984 5 IS 19887:2026 Monocalcium Phosphate, Animal Feed Grade- Specification No earlier standard listed 6 IS 19897:2026 Homoeopathic Mother Tinctures (Hydro-Alcoholic Extracts)- Methods of Test No earlier standard listed 7 IS 19898:2026 Echinacea Angustifolia Hydro-Alcoholic Extract for Use in Homoeopathy- Specification No earlier standard listed 8 IS 19900:2026 Echinacea Angustifolia DC. Whole Plant for Use in Traditional Medicine- Specification No earlier standard listed 9 IS 19901:2026 Safe Handling of Biotherapeutic Products Used in Homoeopathy- Guidelines No earlier standard listed Revised Standards and Concurrent Validity The four older standards do not disappear on 3 August 2026. The Gazette expressly permits them to remain in force concurrently with the 2026 editions until 3 February 2027. This period allows users to manage edition changes, although the notification does not prescribe a detailed migration procedure. New standard Older standard running concurrently Concurrent period ends Scheduled withdrawal IS 5647:2026 IS 5647:2003 3 February 2027 3 February 2027 IS 5649:2026 IS 5649:2003 3 February 2027 3 February 2027 IS 6156:2026 IS 6156:1971 3 February 2027 3 February 2027 IS 10870:2026 IS 10870:1984 3 February 2027 3 February 2027 Concurrent validity does not automatically answer which edition a particular buyer, licence, tender or contract accepts. Users should read the controlling document. If it names an edition, changing that reference may require buyer approval, a contract amendment, updated certification directions or another formal action. New Standards with No Earlier Version Listed For IS 19887:2026, IS 19897:2026, IS 19898:2026, IS 19900:2026 and IS 19901:2026, the columns for an earlier standard and withdrawal date state “NA.” This means the notification does not identify a predecessor for withdrawal. It should not be expanded into a claim that no technical, pharmacopoeial, sectoral or contractual requirements existed previously. The five entries cover: animal-feed grade monocalcium phosphate, test methods for homoeopathic mother tinctures that are hydro-alcoholic extracts, an Echinacea angustifolia hydro-alcoholic extract specification for homoeopathic use, an Echinacea angustifolia DC. whole-plant specification for traditional-medicine use, and guidelines for safe handling of biotherapeutic products used in homoeopathy. Businesses in these fields should map the new standards against existing product specifications, laboratory procedures, pharmacopoeial references, supplier agreements and applicable sectoral laws. That exercise is a practical recommendation, not an express duty created by this Gazette notification. Implementation Timeline and Withdrawal Dates Event Date Affected parties Practical action Establishment of all nine standards 3 August 2026 Users of the listed standards Identify relevant standards and obtain the correct official edition Notification issued 5 August 2026 All stakeholders Record the reference in regulatory trackers Notification published in the Gazette 12 August 2026 All stakeholders Verify the published schedule and dates Concurrent running of four old editions ends 3 February 2027 Users of IS 5647, IS 5649, IS 6156 and IS 10870 Complete edition review before withdrawal Four older standards withdrawn 3 February 2027 Manufacturers, laboratories, procurement and safety teams using those editions Stop relying on the withdrawn edition unless another controlling instrument requires specific treatment No separate compliance deadline is given for the five standards with “NA” in the withdrawal columns. The notification also gives no filing window, application date, fee-payment date or certification transition process. Does This Notification Make BIS Certification Mandatory? No. The notification itself does not direct manufacturers to obtain a BIS licence, Certificate of Conformity, registration or Standard Mark. It establishes Indian Standards and sets concurrent-running and withdrawal dates for four older editions. This conclusion is limited to the document reviewed. Mandatory status must be checked separately because an Indian Standard may become binding through: a Quality Control Order or another specific government order, a reference in legislation or subordinate legislation, a licence, regulatory approval or scheme condition, a tender or procurement requirement, a customer or supply contract, or an existing BIS certification scheme that applies to the product. Before making or marketing a product as “BIS compliant,” businesses should verify both technical conformity and the legal basis for any required certification or marking. Establishment of a standard alone is not permission to use the BIS Standard Mark. Technical and Testing Considerations The Gazette only sets out the standard names and dates. It does not explain what businesses need to follow under each standard in practical terms. Details such as sample size, purity limits, testing equipment, storage conditions, packaging, labelling, quality checks and inspection schedules are not covered in the notification. The appropriate technical review should therefore begin with the full standard: Product specifications: Compare raw materials, grades, test parameters, acceptance criteria, packing and marking clauses, where included in the official standard. Methods of test: Confirm whether laboratories have the method, equipment, reference materials, calibration controls and competent personnel needed for the relevant tests. Codes of safety: Compare handling, storage, process-safety and emergency documentation with the revised code, without assuming the Gazette itself states particular controls. Guidelines: Determine how the guidance connects with internal procedures and any independently binding health, drug, safety or environmental law. Laboratories should not revise an accredited or approved method solely from the standard’s title. They should examine the full method and then follow the applicable accreditation, regulator, customer and change-control requirements. Impact on Businesses The immediate impact is document and edition control. The deeper effect will depend on what changed inside each standard and whether another binding instrument incorporates it. Chemical manufacturers, users and safety teams Businesses dealing with p-Toluidine, o-Toluidine, chlorosulphonic acid or hexane should identify where the older editions appear in specifications, safety procedures, customer approvals, testing plans and purchase orders. The long age of the earlier safety codes 1971 and 1984, makes a structured comparison with the 2026 revisions especially sensible, but the nature of the revisions cannot be inferred from age alone. Animal-feed businesses Manufacturers and suppliers of animal-feed grade monocalcium phosphate now have IS 19887:2026 listed as an established specification. They should examine whether customers, tenders or regulators adopt it. The notification does not itself amend feed law, prescribe certification or state product-compliance deadlines. Homoeopathy and traditional-medicine stakeholders The five standards in this group address test methods, Echinacea material and extracts, and safe handling of biotherapeutic products. Manufacturers, laboratories and quality teams may need to compare them with existing pharmacopoeial, manufacturing, laboratory and handling controls. No claim should be made that the Gazette replaces drug-law requirements. Laboratories and procurement teams Laboratories may need to review their testing methods, equipment, staff training, and accreditation scope once they go through the full standards. Procurement teams should also be clear about which edition they are accepting during the transition period. Mixing test reports or product specifications based on different editions can create confusion, so each case should be checked before acceptance. Stakeholder Immediate Impact Possible Operational or Cost Effect Priority Concern Manufacturers Identify relevant standards and editions Document updates, testing review or process changes may be needed Do not assume mandatory status without checking the controlling instrument Testing laboratories Obtain and compare the 2026 methods or specifications Possible method, equipment, training or accreditation review Use the correct edition and approved change process Safety and EHS teams Review revised chemical-safety codes Procedure and training updates may follow Compare actual clauses before changing controls Procurement teams Update standard references where appropriate Supplier communication and contract changes State accepted editions during the transition Existing licence holders or applicants Check whether BIS issues product-specific transition directions Testing and documentation costs may arise Do not treat the Gazette as the complete certification instruction Benefits for Businesses The standards can provide a common technical reference across suppliers, buyers, laboratories and operational teams. Likely benefits, subject to the content and adoption of each standard, include: clearer edition control for chemical specifications and safety codes, a current reference point for product testing and procurement, more consistent communication of material or product requirements, structured methods for laboratory work where IS 19897:2026 applies, a defined specification for animal-feed grade monocalcium phosphate, recognised references for Echinacea material and hydro-alcoholic extract, and a handling guideline for biotherapeutic products used in homoeopathy. These are potential standardisation benefits. The notification does not guarantee regulatory approval, product quality, market acceptance, lower costs or commercial returns. Challenges and Cost Implications The Gazette states no fee or implementation cost. Any cost will depend on the detailed differences between editions and the way a business uses the standard. Possible cost drivers include purchasing official standards, technical gap analysis, laboratory method review, new equipment or reference materials, staff training, supplier qualification, revised documentation and contract amendments. Certification or laboratory costs should be added only if a separate mandatory or voluntary conformity-assessment route actually applies. MSMEs may need to prioritise the documents that carry the greatest legal, customer or safety relevance. A staged review can begin with binding contracts and regulated products, followed by internal specifications and voluntary improvement work. Best Practices During the Transition Keep a controlled register showing each old and new standard number, issue year, owner and affected process. Obtain the official standard text rather than relying on summaries or the Gazette title. Compare clauses before changing a product specification, test method or safety procedure. Check QCOs, sectoral laws, licences, tenders and contracts separately for mandatory status. Record which edition applies to each batch, test report, purchase order and customer specification during concurrent running. Ask customers or certification bodies to clarify edition acceptance where the controlling document is unclear. Complete internal approval, training and document control before 3 February 2027 for the four withdrawing editions. Preserve evidence of the review and the reason for each adopted change. Common Risks to Avoid Treating 12 August 2026, the publication date, as the standards’ establishment date. Claiming that all nine standards are compulsory merely because they were published in the Gazette. Claiming that the five “NA” entries had no earlier regulatory or technical requirements of any kind. Using the title of a standard as a substitute for reading its technical clauses. Assuming that concurrent running lets every licence holder or supplier choose either edition without checking the controlling terms. Continuing to cite the four older editions after 3 February 2027 without reviewing the effect of withdrawal. Using or advertising the BIS Standard Mark without the required authorisation. Inventing penalties, fees, application steps or testing deadlines that do not appear in the notification. What Businesses Should Do Next 1. Confirm applicability. Match products, materials, tests and handling activities against the nine exact standard titles. 2. Obtain the relevant standards. Use official BIS copies of both the current and earlier editions where comparison is required. 3. Check mandatory status separately. Review QCOs, sector laws, licences, contracts and tender conditions. 4. Perform a clause-level comparison. Identify technical, testing, documentation, safety, packaging or marking changes actually present in the standard. 5. Prepare transition controls. Assign owners and complete necessary updates before 3 February 2027 for the four older editions scheduled for withdrawal. 6. Coordinate external requirements. Confirm expectations with customers, laboratories, certification bodies and suppliers where their approval or action is needed. 7. Maintain evidence. Record the applicable edition, assessment, decisions, approvals, training and revised documents. Action Responsible Team Relevant Date Expected Outcome Determine which standards apply Regulatory, quality and product teams Immediate Clear scope Verify whether adoption is voluntary or binding Legal and regulatory teams Before changing compliance claims or certification plans Correct legal position Compare old and new editions Technical, laboratory and safety teams Before 3 February 2027 for revised standards Evidence-based transition plan Update controlled documents and contracts where required Quality, EHS, procurement and legal teams Before the relevant edition change Consistent documents and supplier expectations Monitor product-specific BIS directions Regulatory and certification teams Ongoing Timely response to any separate implementation instruction How Corpseed Can Help? Corpseed can support businesses that need to understand how the nine standards affect their products, testing arrangements, contracts or certification position. The scope should begin with applicability, because this notification does not make certification mandatory by itself. Applicability assessment for the relevant Indian Standard and product category Review of QCOs and other instruments that may make a standard binding Old-versus-new standard gap assessment using the official editions supplied for review Product and technical-document compliance review Coordination support for laboratory testing where testing is relevant Review of certification pathways and application documentation where a BIS scheme applies Transition planning for standards withdrawn on 3 February 2027 Ongoing regulatory and standard-edition monitoring support A BIS certification consultant should first confirm whether certification is mandatory, voluntary or not applicable. Corpseed assists manufacturers and other stakeholders with this assessment and with the matching product compliance services, without promising certification, approval or a fixed regulatory outcome. Businesses using any of the nine standards may contact Corpseed to speak with a BIS certification consultant about a document-specific applicability and transition review. Key Takeaways BIS notification Ref. HQ-PUB013/1/2020-PUB-BIS (1583) establishes nine Indian Standards from 3 August 2026. Four 2026 revisions will run concurrently with their earlier editions until those older standards are withdrawn on 3 February 2027. Five standards have no predecessor identified in the schedule. The BIS Indian Standards notification 2026 covers chemicals, chemical safety, animal feed, homoeopathy and traditional medicine. The notification is dated 5 August and was published on 12 August 2026. It does not itself impose certification, registration, testing or licensing. Mandatory status must be checked through QCOs, legislation, contracts and other controlling instruments. Affected businesses should obtain the full standards and compare actual clauses before changing operations. Transition planning is most urgent for IS 5647, IS 5649, IS 6156 and IS 10870.

Subject

Summary: The Bureau of Indian Standards (BIS) has notified five BIS medical device standards in 2026 covering microwave therapy apparatus, photodynamic therapy and diagnostic apparatus, home light therapy apparatus, and medical endoscopes and endotherapy apparatus. The standards were developed on 3 August 2026. The notification is dated 5 August 2026 and was published in the Gazette of India on 12 August 2026 under reference HQ-PUB013/1/2020-PUB-BIS (1584). For three revised standards, BIS has allowed the earlier editions to remain in force concurrently until 3 February 2027. The other two entries are shown as new standards with no earlier standard or withdrawal date listed. Manufacturers, importers, testing laboratories, product designers, quality control units, and buyers involved with the equipment listed above need to determine the relevant standard and evaluate the technical documentation during the transition. The notification sets and revokes the standards but does not itself indicate that BIS certification or the Standard Mark is mandatory. Notification at a Glance Particular Verified details Issuing authority Bureau of Indian Standards, Department of Consumer Affairs Date of establishment 3 August 2026 for all five standards Governing provision Rule 15(1) of the Bureau of Indian Standards Rules, 2018 Sector and products Medical electrical equipment; microwave therapy; photodynamic therapy and diagnosis; home light therapy; endoscopes and endotherapy devices Main stakeholders Manufacturers, importers, laboratories, designers, quality and regulatory teams, distributors and institutional purchasers connected with the listed equipment Core development Five standards established; three older editions scheduled for withdrawal Main transition date 3 February 2027 for the three superseded standards Nature of requirement Standard-establishment and withdrawal notification; compulsory certification is not expressly created by this notification Fees or penalties in this notification Not expressly specified The Regulatory Framework BIS is India's national standards body. The present notification was issued under Rule 15(1) of the Bureau of Indian Standards Rules, 2018. Rule 15 deals with the preparation, publication, revision, and withdrawal of Indian Standards. Schedule is the part of this notification that works: it mentions the new edition, its date of adoption, the previous edition, if any, and the date of its withdrawal. This notification should not be confused with a Quality Control Order (QCO). BIS guidance explains that product certification is generally voluntary. At the same time, the Central Government can make conformity and use of the Standard Mark compulsory through a QCO or another applicable legal instrument. No QCO, mandatory Standard Mark direction, license condition, certification scheme, enforcement provision, or penalty appears in this five-page notification. The listed standards draw on publications of the International Electrotechnical Commission (IEC) and the International Organization for Standardization (ISO). The Gazette identifies three IEC-based standards for medical electrical equipment and two ISO-based standards for endoscopes. The technical text of those standards is not reproduced in the notification, so clause-level product requirements must be checked against the complete standards themselves. Scope and Applicability The notification applies only to the five stated standards, not to all devices or all types of electrical medical equipment. Applicability depends on whether the product falls within the scope of any of the mentioned standards. Product or standard group Covered by this notification? Relevant condition Main review area Product or standard group Yes IS 13450 (Part 2/Sec 6): 2026 Basic safety and essential performance requirements in the complete standard Photodynamic therapy and photodynamic diagnosis equipment Yes IS 13450 (Part 2/Sec 75): 2026 Product classification, design and technical evidence against the new standard Photodynamic therapy and photodynamic diagnosis equipment Yes IS 13450 (Part 2/Sec 75): 2026 Scope fit and safety/performance evidence for home-use light therapy equipment Medical endoscopes and endotherapy devices Yes IS 15732 (Part 1): 2026 and/or IS 15732 (Part 4): 2026, depending on the issue assessed General requirements and maximum width of insertion portion Medical devices outside the titles and scopes listed above Not established by this notification Another Indian Standard or regulatory instrument may apply General requirements and maximum width of insertion portion The document does not mention any exemptions, risk classifications, turnovers, locations, or special considerations for MSMEs. In addition, it does not state that all manufacturers, importers, or distributors are obliged to make an application immediately. These considerations depend on the complete standard and the related medical device or BIS instrument. What Has Changed BIS established five standards on the same date. Three are revised editions with six months during which the old and new versions remain in force together. Two are listed without a predecessor.

A business should not assume the changes are limited to the amended years shown in the titles. A proper gap review requires the complete old and new standards. Detailed Standard-Wise Analysis IS 13450 (Part 2/Sec 6): 2026 - Microwave Therapy Equipment This is the first revision of the Indian Standard that contains specific requirements for the basic safety and essential performance of microwave therapy equipment. BIS identifies it with IEC 60601-2-6:2012, Amendment 1:2016, and Amendment 2:2022, in consolidated form, with modifications. Indian Standards of 2018 and their revisions until 2026 will remain relevant until 3rd February 2027. For businesses using the 2018 standard, they can check for changes in the technical specifications between the two versions of the standard and identify which designs, tests, risks, and products will require modification. The notice provides no list of modified clauses and testing. IS 13450 (Part 2/Sec 75): 2026 - Photodynamic Therapy and Diagnosis Equipment This standard address particular requirements for the basic safety and essential performance of photodynamic therapy and photodynamic diagnosis equipment. It is identified with IEC 60601-2-75:2017 and Amendment 1:2023 in consolidated, modified form. The schedule has marked NA for both the earlier standard as well as the withdrawn date of the same. Based on the information provided, the BIS has not identified any predecessor that runs parallel to it. However, this is not conclusive evidence of the absence of any other general/collateral/product standard which may be applicable. IS 13450 (Part 2/Sec 83): 2026 - Home Light Therapy Equipment This new entry covers particular requirements for the basic safety and essential performance of home light therapy equipment. It is linked to IEC 60601-2-83:2019 and Amendment 1:2022 in consolidated, modified form. Unlike Section 75, the Gazette has no precedent for this standard and no withdrawal date. It would be best for manufacturers and importers to ensure that the product falls under the jurisdiction of Section 83 first. This is because the title alone must not determine whether equipment belongs to this category. IS 15732 (Part 1): 2026 - General Requirements for Endoscopes IS 15732 (Part 1): 2026 is the second revision of the general requirements standard for medical endoscopes and endotherapy devices. It adopts ISO 8600-1:2025. The earlier IS 15732 (Part 1): 2018, based on ISO 8600-1:2015, remains in force until 3 February 2027. The heading is rather broad and could influence product specifications and technical documentation across a range of endoscopes and endotherapy devices. The Gazette does not include the new technical provisions. Companies will have to obtain the complete 2026 standard in order to make an accurate comparison. IS 15732 (Part 4): 2026 - Maximum Width of the Insertion Portion IS 15732 (Part 4): 2026 is the second revision of the method for determining the maximum width of the insertion portion of medical endoscopes and endotherapy devices. It adopts ISO 8600-4:2023. The earlier 2021 Indian Standard, based on ISO 8600-4:2014, is scheduled to be withdrawn on 3 February 2027. All concerned teams, engineering, metrology, quality, and testing, should review whether the new procedure modifies any procedures, equipment, acceptance documentation, or product dimensions. Since no figures, tolerances, or procedures are provided in the notice, none should be derived from the title. Meaning of CSV, MOD, and Revision Labels The standard titles contain technical publication labels that help readers identify the source edition but do not replace the full Indian Standard. CSV means consolidated version. IEC explains that a CSV merges a publication and its amendments into a single document. MOD indicates that the Indian Standard is a modified adoption of the referenced international standard. Product teams should therefore use the Indian Standard and identify the national modifications rather than relying only on the IEC text. The first and second revisions identify the revision status of the Indian Standard. They do not, by themselves, describe which clauses changed. NA in the predecessor and withdrawal columns means the schedule lists no earlier standard for withdrawal for that entry. Implementation Timeline/Norms Event Date Affected standards Required or practical action Establishment of all five standards 3 August 2026 All five new standards Treat this as the formal establishment date recorded by BIS Notification date 5 August 2026 Entire notification Record the document date separately from establishment and publication Gazette publication 12 August 2026 Entire notification Use the official Gazette copy for the publication record Concurrent-validity period 3 August 2026 to 2 February 2027 Section 6, Part 1 and Part 4 revised standards Compare editions and plan transition where applicable Withdrawal of three earlier standards 3 February 2027 IS 13450 (Part 2/Sec 6):2018; IS 15732 (Part 1):2018; IS 15732 (Part 4):2021 Stop treating the withdrawn editions as current after the withdrawal date, subject to any separately applicable regulatory directions It is clear from The Gazette that February 3, 2027, is not mentioned as a universal certification deadline. These are just withdrawal dates of three identified standards. Any conversion requirement arising from a license, QCO, purchasing agreement, or medical device approval should be assessed according to the instrument that creates the requirement. Old vs. New Requirements The authenticated comparison is restricted to edition identification, international publication citation, and transfer date due to the absence of the technical content of the standards in the Gazette.

Does This Notification Make BIS Certification Mandatory? This notification does not impose any mandatory BIS certification. This notification issued by BIS is based on Rule 15(1). This rule involves both the establishment of new standards and the discontinuation of existing ones. There is nothing in this notification about the compulsory use of the standard mark. Neither is there any BIS license, conformity assessment scheme, nor any penalty. The BIS's formal guidance on QCO distinguishes between voluntary and mandatory certification through the QCO process. Hence, businesses are required to perform the second check with regard to any QCO, license condition, procurement requirement, regulatory requirement in connection with medical devices, or other legal document that may reference these standards. However, the impact depends on the instrument itself and is not implied by this notice. Impact on Businesses The direct impact on business will be to determine whether a listed standard is applicable and, for revised standards, whether existing technical data remain applicable when the older edition is phased out. Manufacturers and Product Designers Map each model and variant to the relevant standard instead of applying the notification to the entire product portfolio. Obtain the complete 2026 standard before changing product design, specifications, labels, or test plans. Compare old and new clauses for the three revised standards and document the effect on design inputs, risk controls, and verification evidence. For Sections 75 and 83, conduct a fresh scope assessment because no predecessor is listed. Importers, Distributors and Institutional Purchasers Ask suppliers which edition supports the product's technical evidence and whether transition work is planned. Review contracts, tender specifications, and purchase requirements that cite an older standard. Avoid describing the product as legally required to hold BIS certification solely because the standard appears in this notification. Laboratories and Quality Teams Confirm whether test methods, equipment, measurement procedures, and report templates align with the new edition. The two different editions need to be clearly separated during concurrent validation. Include the standard's number and year in the report to avoid confusion. MSMEs and Startups There is no specific transition period or exemption given for MSMEs and startups. Smaller business establishments will find it more challenging to meet standards, conduct gap assessments, and update technical files. Stakeholder Immediate impact Likely operational or cost effect Priority concern Manufacturers Standards mapping and edition comparison Engineering review and possible retesting Product scope and transition plan Importers Supplier evidence review Document updates and supplier coordination Product scope and transition plan Laboratories Method and capability assessment Document updates and supplier coordination Exact requirements of the new edition Purchasers Specification update Tender and contract revision Exact requirements of the new edition MSMEs and startups Applicability check Proportionately higher review cost Focus effort only on relevant products These cost effects are likely implications, not charges imposed by the Gazette. No testing fee, certification fee, or compliance cost is specified in the notification. Benefits for Businesses This amendment ensures companies have a well-defined history of the editions and transition period for three standards. Some possible advantages are: an updated Indian reference based on recent IEC or ISO publications; proper identification of standards belonging to new classes of products such as photodynamic therapy and light therapy equipment; and an opportunity to compare three obsolete editions before withdrawal. more consistent edition references in design, testing, procurement, and quality records; an opportunity to remove outdated specifications from contracts and technical files; and Better coordination among engineering, regulatory, quality, and purchasing teams. These are the practical advantages of proper standards management. The announcement will not ensure any certification, regulation, market access, product safety, or commercial success. Challenges and Cost Implications The main problem here is that the standards are included in the Gazette, but the technical information contained in them is not. A good assessment will require comparing the standards with earlier versions. Possible short-term cost issues might include engineering review, acquisition of standards, lab capability review, supplier coordination, document revision, and testing as necessary according to the gap assessment process. There might also be recurring costs due to the different controls required by the revised method. The quantity or rate cannot be given from this source. Two additional items will require careful consideration. In the absence of an older standard, teams may have to develop a scope and evidence map rather than rely on a migration file. At the same time, teams must determine if any other standards still apply. Risks and Consequences of Non-Compliance There is no punishment prescribed for non-compliance with the notification. Therefore, it would be incorrect to say that failure to meet the deadline of 3 February 2027 will result in a penalty or recall. However, practical risks may emerge if the company continues to reference the withdrawn standard in testing reports, tenders, contracts, and technical specifications. If other binding documents or licenses require the use of the existing Indian Standard, then the consequences of migration should be evaluated separately. Best Practices Maintain a controlled standards register with the exact part, section, year, establishment date, and withdrawal date. Assign an owner for each affected product family and record the scope decision. Obtain the full standards and use a traceable clause-comparison method for revised editions. Separate legal requirements from voluntary technical improvement and customer-specific requirements. Record which external instrument, if any, makes conformity or certification mandatory. Update supplier questionnaires, purchase specifications, and laboratory instructions with the correct edition year. Retain approval for each change to design, testing, or documentation. Common Mistakes or Risks to Avoid Treating the Gazette publication date as the date of establishment. Calling 3 February 2027 a universal certification deadline rather than a withdrawal date for three standards. Assuming “NA” means no other standard or regulation can apply. Using only the referenced IEC or ISO document without checking modifications in the Indian Standard. Claiming BIS certification is mandatory without locating the instrument that creates that duty. Describing technical changes without comparing the complete old and new standards. Applying one listed standard to all medical devices based only on a broad product description. Future Outlook The only confirmed future action in the notification is the withdrawal of three earlier standards on 3 February 2027. No future review, amendment, certification deadline, or additional phase is announced. Companies must keep an eye on BIS and relevant sectoral regulators for manuals, implementation guidance, QCOs, license directions, and any other notices. Monitoring is a practical suggestion and not an action to be taken in the future. What Businesses Should Do Next Priority Action Responsible team Relevant date Expected outcome 1 Identify products potentially covered by the five standards Responsible team Begin promptly Verified product-to-standard map 2 Obtain the complete applicable 2026 standards Responsible team Before technical comparison Authoritative technical source available 3 Compare old and new editions for Sections 6 and Parts 1 and 4 Engineering, quality and laboratory teams Before 3 February 2027 Documented gap assessment and migration plan 4 Conduct fresh scope reviews for Sections 75 and 83 Regulatory and engineering teams Begin promptly Recorded applicability decision 5 Check separately for QCOs, license terms, and sectoral obligations Legal and regulatory teams Before claiming mandatory status Correct legal basis for each obligation 6 Update specifications, reports, and supplier documents Quality, procurement and document-control teams In line with the verified transition plan Consistent edition references 7 Preserve evidence of decisions and approvals Document-control owner Ongoing Traceable standards-management record How Can Corpseed Help? Corpseed supports manufacturers, importers, and other businesses affected by the 2026 BIS medical-device standards update. The support is tailored to the product, applicable standard, and actual compliance requirements. 1. Checking Which BIS Standard Applies Corpseed can help determine whether the new standards cover a particular medical device. Review the product’s purpose, design, and technical features. Identify the relevant BIS standard. Check different models and product variants. Avoid applying an unrelated standard to the product. 2. Mapping Products to the Correct Standards A business may manufacture or import several devices. Each product must be assessed separately. Prepare a product-to-standard mapping. Separate covered products from products outside the notification. Identify the correct standard number, part, section, and year. Create a clear reference for regulatory and quality teams. 3. Comparing Old and New Standards Three earlier standards will remain valid only until 3 February 2027. Corpseed can support a structured comparison when the complete editions are available. Compare the old and revised standards. Identify changes affecting the product. Highlight possible gaps in existing technical records. Prepare a practical transition plan. Help teams prioritize actions before the older standard is withdrawn. 4. Reviewing Technical Documents and Test Reports Technical documents should mention the correct standard and edition. Review product specifications and technical files. Check test reports and supporting records. Identify outdated or incorrect standard references. Review whether available evidence supports the applicable standard. Suggest document updates where necessary. 5. Supporting Product Testing Testing should be arranged only after confirming that it is required and identifying the correct standard. Help determine whether additional testing may be needed. Identify the relevant testing scope. Support coordination with a suitable laboratory. Review whether test reports mention the correct standard and edition. Help organize testing records for future reference. 6. Checking BIS Certification and QCO Applicability The 2026 notification establishes and withdraws standards. It does not, by itself, make BIS certification compulsory. Corpseed can help businesses: Check whether a separate Quality Control Order applies. Review whether a BIS license or Standard Mark is required. Examine other applicable certification or regulatory conditions. Separate voluntary standards from mandatory requirements. Avoid unnecessary certification applications or unsupported compliance claims. 7. Planning the Transition and Ongoing Compliance Businesses using the three older standards should prepare for their withdrawal on 3 February 2027. Create a product-specific transition plan. Assign responsibilities to regulatory, quality, and technical teams. Update internal standards registers and compliance records. Review supplier and laboratory documents. Monitor relevant BIS and regulatory updates. Maintain clear records of compliance decisions and completed actions. A medical device regulatory consultant helps connect the correct product, technical standard, and legal requirement. Corpseed can support businesses dealing with microwave therapy equipment, photodynamic therapy and diagnostic equipment, home light therapy equipment, medical endoscopes, and endotherapy devices. Businesses may contact Corpseed for a document-specific assessment and practical support with medical-device compliance. Certification, approval, or a fixed regulatory result is not guaranteed.
