BIS Establishes 23 New and Revised Indian Standards in 2026: What Businesses Need to Know

The Bureau of Indian Standards (BIS) has issued a notification on the formulation of 23 Indian Standards for various products, machinery, tests, materials, and technical terminology in different sectors.

The BIS notification is dated 1 September 2026 and carries reference HQ-PUB013/1/2020-PUB-BIS (1598). The Schedule attached to it shows that all 23 standards were established on 28 August 2026. 

The update is particularly relevant for manufacturers, laboratories, quality teams, and businesses that still refer to older versions of the affected standards. For several entries, BIS has listed an earlier Indian Standard that will continue for a limited period and is scheduled for withdrawal on 28 February 2027. Other standards in the same notification have no predecessor standard or withdrawal date listed. 

One point needs to be clear from the beginning: this notification should not be read as a blanket order making BIS certification compulsory for all 23 products. It establishes or revises Indian Standards. Whether a particular product requires compulsory BIS certification must be checked separately under the applicable regulatory framework.

BIS Notification at a Glance

The notice has been published under Rule 15(1) of the Bureau of Indian Standards Rules, 2018. According to BIS, Indian Standards specified in the Schedule have been formulated on the dates given opposite to them. If any old Standard has been referred to, such old Standard will remain valid simultaneously up to the date of its withdrawal given in the Schedule. 

What Does the BIS September 2026 Notification Actually Announce?

The notification is mainly about Indian Standards, not about creating one common certification process for all the products listed. BIS has done two different things within the same Schedule. First, it has established 23 Indian Standards on 28 August 2026.

Second, for a number of these standards, it has also identified older editions that are due to be withdrawn on 28 February 2027. This means some entries involve a transition from an older standard to a 2026 edition. Other entries are listed with NA in the column for the standard to be withdrawn and in the withdrawal-date column. That difference matters because the business action will not be identical for every product or standard.

A manufacturer already working with an older Indian Standard may need to check technical documentation and testing references. A business dealing with one of the entries that has no predecessor listed may instead need to understand how the newly established standard fits into its existing product and regulatory framework.

The Regulatory Framework Behind the Notification

Role of the Bureau of Indian Standards

The Bureau of Indian Standards is India's national standards body.

Indian Standards can deal with matters such as:

• product specifications, 
• testing methods, 
• safety requirements, 
• terminology, 
• installation practices, 
• performance requirements, 
• quality parameters, and 
• technical procedures. 

Not every Indian Standard serves the same purpose. A standard may be a product specification, while another may only describe a laboratory test method. That difference can be seen clearly in this notification itself.

For example, IS 14900:2026 is a specification for transparent float glass, whereas IS 7481:2026 deals with the method for determining Protein Efficiency Ratio. 

BIS Rules, 2018

The notification expressly states that it has been issued under sub-rule (1) of Rule 15 of the Bureau of Indian Standards Rules, 2018.  Its immediate purpose is to formally notify the establishment of the standards appearing in the Schedule and, where applicable, the continued operation and future withdrawal of the earlier standards.

Indian Standard and Mandatory BIS Certification Are Not the Same Thing

This difference is particularly crucial for manufacturers and importers. An Indian Standard offers the technical yardstick. The issue of compulsory BIS certification is a different ballgame altogether. An article may require compulsory certification when a law, Quality Control Order, or other such regulation requires conformity to the particular standard.

Therefore, seeing a product name in this Gazette does not, by itself, establish that every manufacturer or importer of that product must immediately apply for a BIS license.

What Has Changed Under the BIS Notification?

The Schedule contains a mixture of revised standards and newly established entries. Broadly, the changes cover:

• product specifications, 
• revised laboratory test methods, 
• agricultural machinery testing, 
• operation and maintenance practices, 
• food and feed testing, 
• terminology and vocabulary, 
• building products, 
• industrial materials, 
• agricultural equipment. 

Some standards replace older editions that were first issued decades ago.

For instance:

• IS 6274:2026 succeeds a 1971 standard on liquid-in-glass thermometer calibration, 
• IS 7481:2026 succeeds a 1974 standard, 
• IS 7815:2026 succeeds a 1975 standard, 
• IS 8168:2026 succeeds a 1976 standard, 
• IS 9019:2026 succeeds a 1979 standard. 

So, for many users, the update is not simply a change in the year printed after an IS number. Older technical references may now need to be reviewed against the revised editions.

Important Dates Businesses Should Understand

There are four dates in this update that should not be mixed.

The 28 February 2027 date is especially easy to misunderstand. It is not described in this notification as:

• a general BIS certification deadline, 
• a universal manufacturing cut-off, 
• an expiry date for every BIS license, 
• a general prohibition on sale. 

It is the withdrawal date given for the specified predecessor standards appearing in the Schedule. 

Complete List of 23 Indian Standards Established by BIS

The 23 standards cover several unrelated sectors, so businesses should identify only the entries connected with their product, testing activity, or technical work.

The complete list appears across pages 6-8 of the English Schedule. 

Which Indian Standards Have Been Revised or Replaced?

The Schedule shows older standards against 15 of the 23 entries. These older editions are scheduled for withdrawal on 28 February 2027.

The case of IS 1973:2026 deserves extra attention. BIS has not linked it with only one earlier standard. The Schedule lists three older standards, IS 1973:1999, IS 6997:2021 and IS 15561:2005, for withdrawal on the same date. 

That means it should not be described casually as a simple revision of one earlier document.

Which Standards Have No Earlier Standard Listed for Withdrawal?

Eight entries show NA under both the earlier-standard and withdrawal columns.

These are:

• IS 101 (Part 2/Sec 6):2026 
• IS 19609:2026 
• IS 19888:2026 
• IS 19890:2026 
• IS 19892:2026 
• IS 19904:2026 
• IS 19910:2026 
• IS 19913:2026 

For these entries, the safest wording is: “The notification does not list a predecessor standard for withdrawal.”

It would not be accurate to automatically say that no related standard existed previously unless that question is checked separately. 

Old and New Standards Will Operate Concurrently Until 28 February 2027

The notification contains a useful transition arrangement.

Where BIS has listed an existing standard for withdrawal, that standard will remain in force alongside the newly established standard until the withdrawal date. 

What Does Concurrent Operation Mean?

Suppose a business is currently referring to one of the older standards listed in the Gazette.

The new 2026 edition was established on 28 August 2026, but the older listed version does not disappear on that date.

Instead, BIS has provided a period during which both remain in force.

For the predecessor standards in this notification, that period ends on 28 February 2027.

This gives manufacturers, laboratories and technical teams time to identify where older references are still being used and assess what needs to change.

What Does 28 February 2027 Actually Mean?

On that date, the predecessor standards identified in the Schedule are due to be withdrawn.

The notification itself does not say that this date automatically:

• cancels a BIS license, 
• stops production, 
• bans sale of stock, 
• requires a product recall, 
• cancels every test report, 
• creates a penalty. 

Such consequences should only be stated where another applicable legal or regulatory requirement supports them.

Industry-Wise View of the 23 Standards

The Gazette itself lists the standards serially. For business readers, however, it is easier to understand them by sector.

The grouping below is only for readability.

Agricultural Machinery and Equipment

This is one of the largest groups in the notification.

Relevant standards include:

• IS 1973:2026 - Sugarcane Juice Extractor 
• IS 6284:2026 - Multi-Crop Thresher Test Code 
• IS 9019:2026 - Installation, Operation and Preventive Maintenance of Power Threshers 
• IS 11691:2026 - Multi-Crop Thresher Specification 
• IS 15831:2026 - Power-Operated Fruits and Vegetables Grader 
• IS 19890:2026 - Electrostatic Spraying System 
• IS 19892:2026 - Agricultural Vehicle Mechanical Coupling 
• IS 19913:2026 - Hammer Mill Specification and Test Code 

Food, Feed and Testing

Relevant standards include:

• IS 7481:2026 
• IS 7815:2026 
• IS 8168:2026 
• IS 9373:2026 
• IS 19888:2026 
• IS 19910:2026 

These deal with testing methods, feed specifications, and industry terminology.

Chemicals, Fertilisers and Explosive-Related Materials

Relevant entries include:

• IS 4668:2026 - Ammonium Nitrate for Explosives 
• IS 6092 (Part 6):2026 - Fertiliser Testing 
• IS 12437:2026 - Zirconium Powder 
• IS 19904:2026 - Shock Tube 

Building and Glass Products

Two entries stand out:

• IS 14900:2026 - Transparent Float Glass 
• IS 19609:2026 - uPVC Profile Framed Doors, Windows and Sliders 

Paints and Coatings

• IS 101 (Part 2/Sec 6):2026 deals with the determination of free formaldehyde in water-dilutable coating materials. 

Major BIS Changes Affecting Agricultural Machinery Businesses

Manufacturers of agricultural machinery should look closely at this notification because several equipment-related standards have either been revised or newly established.

Sugarcane Juice Extractors

IS 1973:2026 is the fourth revision of the standard for sugarcane juice extractors and covers specifications and testing.

What makes this entry different is that BIS has listed three earlier documents for withdrawal:

• IS 1973:1999 - Sugarcane Crushers - Specification 
• IS 6997:2021 - Sugarcane Crushers - Test Method 
• IS 15561:2005 - Sugarcane Crushers - Safety Requirements 

All three are listed for withdrawal on 28 February 2027. 

Manufacturers working with these older references should therefore check where the documents appear in:

• product specifications, 
• testing plans, 
• safety documentation, 
• customer specifications, 
• quality-control records. 

Multi-Crop Threshers

There are multiple thresher-related entries. IS 6284:2026 provides a test code for multi-crop threshers, while IS 11691:2026 provides a specification for them. Older versions of both standards are listed for withdrawal on 28 February 2027. This means manufacturers need to review both the product specification side and the testing side rather than looking at only one standard.

Power Thresher Installation and Maintenance

IS 9019:2026 deals with installation, operation, and preventive maintenance of power threshers. It succeeds IS 9019:1979, which BIS has scheduled for withdrawal on 28 February 2027. 

Fruit and Vegetable Graders

IS 15831:2026 covers power-operated fruit and vegetable graders based on size. The older IS 15831:2009, which dealt with citrus graders, is listed for withdrawal. 

New Agricultural Equipment Entries

• Some agricultural standards have no predecessor listed in the notification. These include:
• IS 19890:2026 for electrostatic spraying systems 
• IS 19892:2026 for mechanical coupling between agricultural vehicles, 
• IS 19913:2026 for hammer mills. 

Businesses dealing with these products should focus on understanding the new technical standard and separately check whether any mandatory regulatory requirement applies.

What Changes for Food, Feed and Testing Laboratories?

The notification is also relevant to laboratories and businesses dealing with food, animal feed and analytical testing.

Protein Efficiency Ratio

IS 7481:2026 deals with determination of Protein Efficiency Ratio. The earlier 1974 standard is due to be withdrawn on 28 February 2027. A laboratory still citing IS 7481:1974 in SOPs or reports may therefore need to review the revised edition before the earlier version is withdrawn.

Amino Acids in Foods and Feeds

IS 7815:2026 covers determination of amino acids in foods and feeds. Its predecessor, IS 7815:1975, is listed for withdrawal. 

Food-Grade Amino Acids and Premixes

IS 8168:2026 deals with determination of lysine, methionine and threonine in food-grade amino acids and premixes-the earlier IS 8168:1976 covered determination of available lysine in foods. The scope described in the titles has therefore changed enough that laboratories should review the actual standard rather than assuming the new edition is simply a wording update.

Compounded Feed for Sheep and Goat

The IS 19888:2026 specifies the requirements for compounded feed for sheep and goats. There is no previous standard mentioned for this particular notification. 

Animal Feeding Stuffs Vocabulary

IS 19910:2026 / ISO 20588:2019 deals with vocabulary used for animal feeding stuffs. Again, the Schedule shows no predecessor standard for withdrawal. 

Other Important Industrial Standards Covered

Transparent Float Glass

IS 14900:2018 covers clear and extra clear float glass. It is the second revision. IS 14900:2018 has been listed for withdrawal on 28th February 2027. Companies and organizations making use of the standard IS 14900:2018 should consider referring to the revised version.

uPVC Doors, Windows and Sliders

IS 19609:2026 covers uPVC profile framed doors, windows and sliders. No predecessor standard or withdrawal date is shown against this entry in the notification. 

Ammonium Nitrate for Explosives

IS 4668:2026 is the second revision of the specification for ammonium nitrate for explosives. The earlier IS 4668:1985 is scheduled for withdrawal on 28 February 2027. 

Zirconium Powder

IS 12437:2026 covers zirconium powder used in the explosive and pyrotechnic industry. IS 12437:1988 will be withdrawn on 28 February 2027. 

Thermometer Calibration

IS 6274:2026 deals with the calibration of liquid-in-glass thermometers. Its predecessor dates back to 1971 and is now listed for withdrawal. 

Does This Notification Make BIS Certification Mandatory?

This notification does not state that all 23 listed standards are now subject to compulsory BIS certification. This is the part businesses should check most carefully. A BIS standard and a mandatory BIS certification requirement are related concepts, but they are not automatically the same thing. Before assuming certification is required, manufacturers and importers should check:

1. Whether a Quality Control Order Exists for the Product

The product could be covered by mandatory conformity through a specific product's Quality Control Order.

2. Whether the Product is Included Under the Mandatory BIS Scheme

Certain products are covered by mandatory certification under other provisions.

3. Whether Another Authority Has Adopted the Standard

An Indian Standard can become relevant under another ministry's or regulator's rules.

4. Whether an Existing BIS License Refers to the Earlier Edition

The licensees must determine whether the standard revision impacts the existing license.

5. Whether BIS Has Provided Product-Specific Transition Guidance

A standards notification should not be substituted for a specific transition order or certification direction.

This is where professional BIS certification services can be useful. Before beginning an application or modifying an existing certification, businesses should first establish whether a certification obligation actually applies to their product.

Indian Standard vs Mandatory BIS Certification

A manufacturer should therefore ask two separate questions:

What technical standard now applies? And is compliance with that standard compulsory for this product? 

Treating these as one question can lead to unnecessary applications or missed compliance obligations.

Impact on Manufacturers

For manufacturers, the main task is to find out whether one of the listed standards is already being used in day-to-day operations. The standard may appear in places that are easy to overlook.

Product Specifications

Check whether design or product specifications still refer to an older edition.

Quality Plans

Quality-control plans may contain test values, inspection references, or standard numbers taken from the earlier document.

Supplier Requirements

The purchasing specification can require compliance with the preceding IS number and year.

Testing Documentation

The internal testing process and external test requirements can still refer to the previous standard.

Customer and Tender Requirements

Customer contracts and government or private tenders can refer to specific standard versions. Manufacturers should not simply replace an old standard number with a new one without checking the revised technical content. A standard revision may affect more than the title or year.

Impact on Testing Laboratories and Quality-Control Teams

Laboratories should pay particular attention because several standards in the Gazette relate directly to test methods. These include tests concerning:

• formaldehyde in coatings, 
• fertiliser moisture and impurities, 
• thermometer calibration, 
• protein efficiency, 
• amino acids, 
• food-grade amino acids and premixes, 
• agricultural machinery performance. 

Where relevant, laboratories may need to review the following:

Laboratory SOPs

Check whether SOPs cite one of the predecessor standards.

Test Reports

Report formats may still show an old standard number or year.

Testing Methodology

The technical method itself should be compared with the revised document rather than assuming there is no substantive change.

Equipment and Method Suitability

If the amended methodology changes the test method, the laboratory must evaluate whether current equipment and controls are still applicable.

Accreditation Scope

In cases where the accredited scope of the laboratory is dependent on a certain version of a standard, an independent assessment of impact needs to be done. The Gazette itself does not state that accreditation changes automatically.

Impact on Existing BIS License Holders

A business already holding a BIS license should not assume that the license becomes invalid simply because the underlying standard has been revised. The sensible approach is to review the product-specific position. That may include checking:

• the standard edition mentioned in the license, 
• applicable BIS guidelines, 
• any transition circular or direction, 
• testing requirements, 
• the applicable Quality Control Order, 
• whether a license amendment is required, 
• the date from which any revised requirement has to be followed. 

The September notification itself does not give one common license-transition process for all 23 standards.

Existing license holders may therefore benefit from a BIS certification consultant who can examine the product-specific position rather than applying a generic rule.

Standards Without a Withdrawal Period in This Notification

The February 2027 withdrawal date is not appropriate for application to each of the standards listed in the Schedule. There are eight items which have a value of NA for the preceding standard as well as the withdrawal date. Therefore, there is no transition period on the basis of withdrawing an earlier standard. Businesses dealing with those products should instead ask:

• What does the new standard cover? 
• Does the business currently use any other technical reference? 
• Is the product covered by compulsory BIS certification? 
• Has any ministry or regulator adopted the standard? 
• Does the standard affect testing, procurement, or customer specifications? 

That is a different exercise from transitioning away from an explicitly listed predecessor standard.

Standard-Specific Business Impact Matrix

What Should Businesses Review Before 28 February 2027?

Not every company needs the same response. For businesses that currently use one of the predecessor standards listed in the Gazette, the following review makes sense.

1. Locate Where the Old Standard is Applied

Check: 

• drawings,
• SOP’s,
• test reports,
• suppliers’ documentation,
• purchase orders,
• customers’ specifications,
• quality manuals, 
• licenses/certificates (as applicable).

2. Locate the 2026 Equivalent Standard

Link the older standard to the corresponding new edition that is listed in the Gazette.

3. Retrieve and Evaluate the Technical Changes Made

Do not be limited by the Gazette title. It is the technical differences that appear in the Indian Standard.

4. Testing References

If there is any testing, ensure that the test or reporting reference requires changes.

5. Mandatory Certification Separate Evaluation

Ensure that you look at the specific QCO, BIS Scheme, or any other regulation instead of relying on the certification requirements of the standards notification alone.

6. License Condition Review

For current license holders, look for BIS transition instructions for the specific product.

7. Document Changes Before Withdrawal

If the existing standard is to be withdrawn, try not to wait until the withdrawal date to effect all the changes. This is just a practical list of things to check. It is not mandated by the notification itself.

What This BIS Notification Does Not Specify

A short Gazette notification can easily be overread. This one does not expressly provide a common rule for:

• BIS application fees, 
• certification fees, 
• laboratory testing charges, 
• processing time, 
• documents required for certification, 
• inspection frequency, 
• license-renewal procedure, 
• product-specific QCO deadlines, 
• penalties, 
• compulsory certification for all 23 standards, 
• transition of every existing BIS license. 

Businesses should therefore avoid copying generic BIS procedures into their compliance plan without first checking whether they apply to the specific product.

Benefits of Updated Indian Standards for Businesses

Updated standards can be useful where older technical documents no longer fully reflect current products, test practices or terminology. Depending on the particular standard, the revision may help businesses work with:

• updated technical references,
• updated testing procedures,
• updated product specifications,
• uniform terminology,
• updated quality control processes,
• updated procurement references,
• up-to-date technical documentation.

The exact benefit will differ from one standard to another. A revised laboratory method, for example, affects a business differently from a revised product specification.

Transition and Compliance Challenges

Updating Old Technical References

Older IS numbers can appear in many documents across a company. Finding all of them may take time, especially where product, quality, procurement, and testing teams maintain separate records.

Understanding the Technical Difference

A new year after an IS number does not tell a business what has actually changed. The old and new documents need to be compared.

Laboratory Adjustment

Testing teams may need to update methods, SOP references, or reports.

Supplier Coordination

Suppliers may continue quoting older specifications unless the revised requirement is communicated clearly.

Certification Confusion

The biggest compliance risk is assuming that a revised standard automatically means a fresh BIS certification application is required. That decision should be based on the product-specific legal position.

Cost of Transition

It is possible that costs will be incurred if the amendment results in additional testing, change in technical documentation, modification of products, or certification process. The notification does not mention any fixed cost amounts.

Risks Businesses Should Avoid

The following should not be understood as follows:

• "23 products have become mandatory for BIS certification." 
• "28 February 2027 is the certification date for all products." 
• “Every existing license expires on that date.” 
• “NA means certification is immediately compulsory.” 
• “The old and new standards are technically identical.” 
• “Only the standard number needs to be changed in documents.” 
• “All testing laboratories need to change their accreditation immediately.” 
• “The Gazette alone contains the full certification process.” 

None of these conclusions should be drawn without supporting regulatory information.

What Businesses Should Do Next

Check Whether the Product Appears in the Notification

Start with the exact product, activity, or test method.

Identify the Relevant Standard Number

Do not rely only on a product name.

Check Whether BIS Lists an Older Standard

If yes, note the withdrawal date.

Review the New Technical Document

Compare the actual 2026 standard with the version currently being used.

Check Mandatory BIS Applicability

Determine if there is any relevant QCO and/or compulsory certification regime applicable to the product.

Review of Existing Certification

For license holders, check BIS product-specific guidelines before modifying the compliance structure.

Updating of Technical Documentation

If needed, ensure that the company’s internal standards, test results, and quality documentation correspond.

Keep Checking for BIS Notifications

One standard update and one compulsory certification guideline might come from separate regulatory guidelines.

How Can Corpseed Help With BIS and Product Compliance?

A standards notification can tell a business that a technical document has changed, but it does not always answer the next question: What does this mean for our product?

Corpseed's BIS certification services can support manufacturers, importers, and other businesses in understanding the product-specific compliance position before they begin an application or make changes to existing certification.

BIS Applicability Assessment

The first step is to check whether the standard is actually relevant to the business.

Corpseed can assist in reviewing:

• product classification, 
• applicable Indian Standard, 
• Revision status,
• Former standard and withdrawal date,
• BIS certification applicability,
• Quality Control Order applicable, if any,
• Existing compliance status.

This helps ensure that all BIS Gazettes are not treated as compulsory certification orders.

BIS Certification Services

Where mandatory BIS certification is applicable, Corpseed can assist companies in meeting the certification requirements relevant to them. The level of assistance provided will depend on the product, certification program, and requirement involved. Assistance will involve analyzing the relevant requirement, compliance with respect to the application, and coordination related to the certification.

Product Compliance Services

A product may fall under more than one technical or regulatory requirement. Through product compliance services, Corpseed can help businesses understand how the relevant Indian Standard fits with the wider compliance position applicable to the product. This can be useful for manufacturers that are unsure whether they are dealing with:

• a voluntary technical standard, 
• a mandatory certification requirement, 
• a product-specific QCO, 
• another regulatory approval. 

Product Regulatory Consulting

Where the compliance position is not straightforward, product regulatory consulting can help identify the correct regulatory route before the business invests time or money in testing and certification. The review can focus on the product, applicable standard, regulator, and current compliance requirement.

Standard Transition Review

Companies still working under the previous standard will be assisted in verifying the following:

• Previous version
• Revised 2026 version
• Withdrawal date
• BIS changes
• Certification implications, if any. 

Technical Documentation Review

Corpseed can assist in reviewing technical documentation connected with the applicable compliance requirement. The documents should be identified from the actual certification or regulatory framework rather than from a standard generic checklist.

Product Testing and Laboratory Coordination

Where the testing of products is needed, Corpseed can assist in understanding the testing requirements and getting in touch with the right laboratories. The extent of testing needs to be determined based on the standard and certification requirements.

Existing BIS License Review

Businesses already holding a BIS license may need to review their current compliance position. Corpseed can assist in checking:

• the standard mentioned in the existing license,
• the updated standard,
• relevant BIS directions,
• applicable transition requirements, and
• any further action that may be needed.

Technical Compliance Consulting

For businesses dealing with revised testing methods, product specifications, or several regulatory requirements at once, technical compliance consulting can help bring the technical and legal position together.

The aim is to determine what needs action and what does not before the company changes products, testing arrangements, or certification records.

Businesses that are unsure whether one of the 23 standards affects their product can first seek a product-specific applicability review rather than immediately beginning a certification application.

Key Takeaways

The BIS notification is mainly a standards update, but its impact differs considerably from one entry to another.

• BIS has established 23 Indian Standards. 
• All 23 are shown with an establishment date of 28 August 2026. 
• The notification is dated 1 September 2026. 
• Fifteen entries have predecessor standards listed for withdrawal on 28 February 2027. 
• Eight entries do not have a predecessor standard or withdrawal date listed in this Gazette. 
• Listed older standards continue concurrently until their withdrawal date. 
• The Gazette does not state that all 23 products have become subject to compulsory BIS certification. 
• Manufacturers should review old technical, testing and quality references where relevant. 
• Laboratories should pay particular attention to revised test-method standards. 
• Existing BIS license holders should check product-specific transition directions separately. 
• A BIS certification consultant or appropriate compliance professional can help determine whether certification, testing, or only a technical-document review is actually required.
