Legal Metrology Notification 2026: 51 Test Centre Approvals Across India

The Central Government has notified 51 Government-Approved Test Centre (GATC) entries for the verification of weighing and measuring instruments in India.

Issued on 13 October 2026, Notification S.O. 5620(E) identifies testing centres authorised to verify instruments such as weighing machines, gas meters, energy meters, clinical thermometers, breath analysers and other measuring equipment.

The notification provides the name and address of each centre, its approval certificate number, the instruments covered and the date until which the approval is valid.

For manufacturers, equipment suppliers and businesses using regulated measuring instruments, the list provides an official reference for identifying suitable verification centres.

However, the notification does not require every business to obtain a new Legal Metrology licence. It concerns the recognition of testing centres under an existing regulatory framework.

Legal Metrology Notification 2026: Key Details

The Department of Consumer Affairs issued the notification under Section 24(3) of the Legal Metrology Act, 2009, read with Rule 4(1) and Rule 13(3) of the Legal Metrology (Government Approved Test Centre) Rules, 2013.

The following table brings together the important details.

The 51 entries should not be mistaken for 51 separate physical testing centres. A single organisation may hold more than one approval for different types of instruments.

This distinction is particularly important when examining the certificate numbers listed in the Gazette.

Understanding Government-Approved Test Centres Under Legal Metrology

What Is a Government-Approved Test Centre?

A Government-Approved Test Centre is an organisation recognised under the Legal Metrology framework to verify specified categories of weights and measuring instruments.

Verification is the regulatory process used to establish whether an instrument meets the applicable Legal Metrology requirements.

This matters in commercial activities where the measured quantity determines how goods or services are supplied, priced or billed.

A general calibration report and statutory Legal Metrology verification are not necessarily the same thing. The applicable rules determine what kind of verification is required and who may conduct it.

What Does the Legal Metrology Act, 2009 Require?

Section 24 of the Legal Metrology Act deals with verification and stamping of weights and measures.

Subject to its conditions, Section 24(1) requires verification before certain weights and measures are used or likely to be used in transactions or for protection.

The law also provides for the recognition of Government-Approved Test Centres.

The practical question for a business is therefore not simply whether it owns a weighing machine or measuring device. It must establish whether the instrument falls within the regulated category and whether its use brings it within the applicable verification requirements.

What Changed Under the 2025 and 2026 GATC Amendments?

The October notification should be read alongside earlier changes to the GATC Rules.

The Legal Metrology (Government Approved Test Centre) Amendment Rules, 2025 amended Rule 3(1) to allow instruments specified in the First Schedule to be verified either by a Government-Approved Test Centre or by Legal Metrology officers.

A further amendment dated 8 May 2026 substituted the First Schedule, setting out the instruments covered under the GATC framework.

The Second Amendment Rules, dated 17 June 2026, separately revised the fee payable when a Government-Approved Test Centre renews its recognition. The prescribed renewal fee is ₹10,000 for one year in respect of each equipment.

These are separate regulatory developments. The October 2026 notification itself identifies approved testing centres; it does not introduce those earlier amendments.

What Has the Government Notified Under S.O. 5620(E)?

The Gazette provides a detailed list of Government-Approved Test Centres, but the most important information is found in three parts of each entry: the certificate number, the instrument covered and the validity date.

Approval Is Linked to a Particular Instrument

A testing organisation may be approved for one or several categories of equipment.

For instance, the Gazette lists Yadav Measurements Private Limited, Rajasthan, under two separate certificate numbers:

• IND/GATC/RJ/25/03 - Gas meters.
• IND/GATC/RJ/25/04 - Energy meters.

Both entries carry a validity date of 23 December 2026.

The separate approvals show why businesses should check the specific instrument category instead of relying only on the testing centre's name.

One Testing Centre May Have Multiple Certificates

Another example is TestLa Testing Centre Private Limited, located in Navi Mumbai.

The Gazette lists separate approvals for sphygmomanometers, clinical thermometers, non-automatic weighing instruments and weights.

The four entries have different certificate numbers, although they refer to the same organisation and location.

This is why the number of approvals should not be presented as the number of unique testing facilities.

Approval Validity Is Also Specified

The notification records the expiry date associated with each approval entry.

Businesses should check that the relevant approval covers the instrument they wish to have verified and that its validity has not expired.

A later renewal or amendment may affect the current status. The October Gazette alone cannot establish a centre's approval status beyond its listed date.

Which Weighing and Measuring Instruments Are Covered?

The notification covers equipment used in different industries, from commercial weighing operations to gas measurement and medical applications.

The following categories appear in the Gazette.

A. Non-Automatic Weighing Instruments

These are weighing instruments that require an operator's intervention during the weighing process.

The Gazette includes approvals for:

• Non-automatic weighing instruments of Accuracy Class III, up to 150 kg.
• Non-automatic weighing instruments of Accuracy Class IIII.

The accuracy class and maximum capacity matter because an approval for one class or capacity should not be treated as an approval for every weighing instrument.

Manufacturers, dealers and businesses using regulated weighing equipment should check the exact specification of the instrument concerned.

B. Gas, Water, Energy and Flow Meters

Several entries relate to equipment used to measure gas, water, energy or fluid flow.

These instruments may be used in utilities, manufacturing facilities, industrial processes and other measurement-dependent activities.

The Gazette separately identifies centres authorised for:

• Gas meters.
• Water meters.
• Energy meters.
• Flow meters.

A testing centre approved for gas meters is not automatically approved for all other meter types.

C. Clinical Thermometers and Sphygmomanometers

The notification includes centres approved for verification of certain medical measuring instruments.

Clinical thermometers measure body temperature, while sphygmomanometers are used to measure blood pressure.

Accurate readings are particularly important in healthcare.

However, inclusion in this Legal Metrology notification does not mean that the government has introduced a new CDSCO registration requirement. Medical-device compliance and Legal Metrology verification are separate regulatory matters that may both need consideration, depending on the product.

D. Tape Measures, Speed Meters and Rail Weighbridges

The Gazette also covers instruments used for length measurement, vehicle-speed measurement and railway weighing activities.

These include tape measures, speed meters for vehicles and automatic rail weighbridges.

E. Breath Analysers and Standard Weights

Breath analysers and standard weights also feature in the notified approvals.

The exact scope differs by certificate. For example, one entry covers weights of all categories up to 20 kg, while other entries use broader category descriptions.

Businesses should retain these distinctions when checking a test centre's approval.

Instrument-Wise Summary

The table illustrates possible areas of use. It does not mean every organisation in these sectors automatically has a new obligation under the October notification.

State-Wise Government-Approved Test Centres in India

The Gazette covers 51 approval entries across 13 states and the National Capital Territory of Delhi.

Maharashtra has the highest number of entries in this particular notification, followed by Gujarat and Haryana.

The distribution is as follows.

These numbers relate only to the approvals appearing in S.O. 5620(E). They are not a complete count of every Government-Approved Test Centre operating in India.

Approved Test Centres in Maharashtra

Maharashtra accounts for 12 entries covering several instrument categories.

Among the organisations listed are Green Globe Fuel Solutions Private Limited, Pietro Fiorentini DB India Private Limited, Weighcal Metrology Services Private Limited, TestLa Testing Centre Private Limited and Qualilab Industries Private Limited.

The range of approved instruments includes gas meters, weighing equipment, clinical thermometers, sphygmomanometers and breath analysers.

Approved Test Centres in Gujarat

Gujarat has six entries, including approvals associated with Axpert Enterprise, Smartmeters Technologies Private Limited, Divy Calibration and Testing Center Private Limited and Flow Metering Technology Private Limited.

The notified categories include gas meters, weighing instruments and certain medical measuring instruments.

Approved Test Centres in Haryana

Haryana also accounts for six approval entries.

The list includes Midas Touch Metalloys Private Limited, Yorker Engineering Private Limited, Saini Scales and Precision Electronic Instruments Co.

Precision Electronic Instruments Co. has separate entries for tape measures and two categories of non-automatic weighing instruments.

Approved Test Centres in Uttar Pradesh

Uttar Pradesh has five entries involving weighing instruments, vehicle speed meters, gas meters and flow meters.

The named organisations include CIVA Industrial Solutions, Bhaskar Scale Engineering, Pulenergy Metrovis India Private Limited and Rockwin Flowmeter India Private Limited.

Rockwin Flowmeter India Private Limited appears under separate approvals for gas meters and flow meters.

Why the State-Wise List Matters

A business may prefer a verification provider located within a practical distance of its operations. However, the closest centre is not necessarily the right one.

Instrument coverage, approval conditions and certificate validity remain important.

The complete Gazette table should therefore be checked before making a final selection.

Government-Approved Test Centre Certificate Validity: Important Dates

The approvals listed in the notification do not all expire on the same date.

The earliest validity date is 23 December 2026, while the latest is 28 June 2027.

Approval Validity by Period

The exact expiry date should always be checked against the individual approval.

Does the Certificate Expiry Date Apply to Every Business?

No. These are validity dates associated with Government-Approved Test Centre authorisations.

They should not be interpreted as deadlines requiring all manufacturers, dealers or commercial establishments to complete verification by those dates.

Verification obligations and their timing must be determined separately under the applicable Legal Metrology provisions.

What Should Businesses Check Before an Approval Expires?

Before relying on a listed test centre, it is sensible to confirm:

1. Certificate identity: Whether the certificate number matches the centre and instrument.
2. Instrument coverage: Whether the approval extends to the exact instrument category and relevant capacity or accuracy class.
3. Validity: Whether the approval covers the intended verification date.
4. Current status: Whether any renewal, amendment or subsequent notification affects the approval.

The Gazette provides the starting information, but businesses should use current official records when confirmation is required.

Who Should Pay Attention to the Legal Metrology Notification 2026?

Not every business will be directly affected by the publication of the new list.

Its practical relevance depends on the equipment involved and the activity for which it is used.

Manufacturers of Weighing and Measuring Instruments

Manufacturers dealing with regulated measuring instruments may need to arrange verification under the applicable law.

The Gazette helps identify recognised centres for particular categories, but it does not replace the rules governing manufacturing, model approval or verification.

Businesses should also check whether they require a separate Legal Metrology manufacturer licence.

Dealers and Suppliers of Measuring Equipment

Dealers and suppliers may need to understand the verification status of regulated instruments and any applicable licensing requirements.

Where an instrument requires statutory verification, the relevant authority and permitted verification arrangements should be confirmed.

Businesses Using Regulated Measuring Instruments

Businesses using weighing machines, meters or other measuring equipment for regulated purposes should determine whether their instruments are subject to verification.

The October notification may assist them in identifying an approved centre where appropriate.

Testing and Calibration Organisations

Testing laboratories and calibration businesses should distinguish between their technical capabilities and statutory recognition under the GATC Rules.

Only the instrument categories and conditions covered by an approval should be treated as falling within its notified scope.

Does the Notification Introduce a New Legal Metrology Licence or Registration Requirement?

This is an important distinction for businesses.

Notification S.O. 5620(E) does not introduce a new general licence or registration requirement for manufacturers, traders, importers or instrument users.

Its purpose is to notify Government-Approved Test Centres.

Businesses may still have existing obligations under other Legal Metrology provisions, but those obligations should not be described as new requirements introduced by this particular Gazette.

Legal Metrology Verification and Registration Are Different

The terms are sometimes used together, but they address different regulatory matters.

Can Legal Metrology Officers Verify Instruments?

The 2025 GATC Amendment Rules amended Rule 3(1) to provide for verification of First Schedule instruments by Government-Approved Test Centres or Legal Metrology officers.

Businesses should therefore examine the applicable verification route rather than assuming that the October Gazette requires them to use only the listed testing organisations.

Have Verification Fees Increased Under This Notification?

S.O. 5620(E) does not itself introduce new verification fees.

Earlier amendments to the GATC Rules address certain verification fees and recognition-renewal fees separately.

For example, the June 2026 Second Amendment Rules prescribe ₹10,000 for renewal of a GATC's recognition for one year in respect of each equipment.

That amount concerns the renewal of a test centre's recognition. It should not be described as a universal verification charge payable by all businesses.

How to Choose an Appropriate Government-Approved Test Centre

Selecting a testing centre should involve more than checking its name or location.

Businesses can review the following points before arranging verification.

Confirm the Correct Instrument Category

Start with the technical description of the instrument.

For weighing equipment, identify the applicable accuracy class and capacity. For meters and specialised instruments, check that the centre's approval specifically covers the relevant category.

Check the Approval Certificate

Match the approval certificate number against the official Gazette entry.

Where one organisation holds several approvals, identify the certificate corresponding to the relevant instrument.

Verify the Centre's Location

Check the name and address recorded in the approval.

This is particularly important where an organisation operates at multiple premises or has different offices and laboratory locations.

Review the Approval Validity

Check the expiry date and confirm whether later official information has changed the status.

A centre's continued business operation does not, by itself, establish that every earlier statutory approval remains valid.

Check the Applicable Verification Route

Businesses should determine whether the instrument can be verified through a Government-Approved Test Centre or Legal Metrology officers, taking the governing rules into account.

These checks are practical safeguards. The October notification does not establish a separate application process for businesses selecting a centre.

What Does the Notification Mean for Manufacturers and Other Businesses?

The value of the October notification lies in the specific information it makes available.

Greater Clarity About Instrument Coverage

The Gazette records which organisations have approvals for particular instrument categories.

This can help manufacturers and equipment suppliers avoid treating all testing providers as interchangeable.

Better Planning for Verification Arrangements

Businesses dealing with regulated measuring equipment can use the information when reviewing possible verification arrangements.

That may be useful where a product has specific technical characteristics or only certain approved centres cover its category.

Importance of Checking Certificate Validity

The separate expiry dates are worth paying attention to.

A centre that appears in the Gazette may require a later approval or renewal before it can be relied upon for verification after the listed date.

Continued Need for Broader Legal Metrology Compliance

The notification does not replace other applicable requirements.

Manufacturers, dealers, repairers and importers should still assess whether they need separate licences, registrations, approvals or declarations under the relevant Legal Metrology rules.

This is where a wider compliance review may be useful, particularly for businesses handling several product categories.

What Should Businesses Do After the October 2026 Notification?

There is no new general application deadline created by the notification. Businesses should instead use the published information to review their existing arrangements.

The following checklist can help.

A. Review the Instruments Used or Supplied

Identify the relevant instruments and record their technical details.

For weighing equipment, note the accuracy class and maximum capacity where applicable.

B. Confirm Whether Verification Is Required

Check the Legal Metrology Act and applicable rules to understand whether the instrument and its intended use fall within verification requirements.

Do not rely on the October notification alone to establish a legal obligation.

C. Check the Appropriate Verification Authority

Where verification is required, establish the permitted verification route.

The applicable framework may provide for verification through Legal Metrology officers or a Government-Approved Test Centre.

D. Match the Instrument With a Notified Approval

Check the centre's approval certificate number, authorised instrument category, location and validity date.

E. Maintain Applicable Records

Keep the verification records, licences and supporting documentation required under the relevant provisions.

Any statutory record-retention requirement should be established from the applicable law rather than assumed from the Gazette list.

F. Review Separate Registration and Licensing Requirements

Businesses involved in manufacturing, repairing, dealing in or importing regulated products should assess whether separate Legal Metrology registration or licensing provisions apply.

This assessment is independent of the October test-centre notification.

How Corpseed Can Help With Legal Metrology Registration and Compliance

A Government-Approved Test Centre notification may answer where a particular instrument can be verified, but it does not resolve every Legal Metrology question a business might have.

Manufacturers and suppliers may also need to understand licensing, verification, model approval or other requirements relevant to their activities.

Corpseed offers Legal Metrology registration services and related regulatory assistance for businesses dealing with applicable compliance requirements.

Legal Metrology Registration Services for Manufacturers and Dealers

Businesses manufacturing, dealing in or repairing regulated weights and measures may be required to obtain relevant licences under applicable rules.

Corpseed can assist businesses with understanding and preparing for relevant Legal Metrology registration or licensing requirements within its service scope.

Legal Metrology Compliance Services

Businesses dealing with several categories of measuring instruments may need to assess which obligations apply to each activity.

Professional compliance assistance can help clarify the relevant registrations, approvals and documentation requirements.

LMPC Registration Services for Importers

Importers of applicable pre-packaged commodities may have separate registration obligations under the Legal Metrology (Packaged Commodities) Rules, 2011.

Corpseed also provides assistance through its LMPC Certificate for Import service.

However, an LMPC certificate should not be confused with a weighing-machine verification certificate or Government-Approved Test Centre recognition.

If your business manufactures, imports, supplies or deals with regulated measuring instruments, understanding the correct Legal Metrology requirements is important.

Contact Corpseed for assistance with applicable Legal Metrology registration, licensing and regulatory documentation requirements.

Key Takeaways

The October 2026 Legal Metrology notification provides an official list of Government-Approved Test Centre approvals for specified measuring instruments.

It contains 51 approval entries across 13 states and Delhi, with separate certificate numbers, instrument categories and validity dates.

For businesses, the key point is to match the instrument with an appropriately approved centre and confirm the current validity of that approval.

The notification does not create a new general registration deadline, and it should not be confused with separate requirements for Legal Metrology licensing, model approval or LMPC registration.

Businesses should continue to assess their existing obligations under the Legal Metrology Act and applicable rules.
