Verification and Stamping of Weights and Measures under Legal Metrology

Updated 11 October 2026 · Fact-checked

Under the Legal Metrology Act, 2009, anyone who holds a weight or measure likely to be used in a transaction or for protection must get it verified before using it (Section 24). Verification happens at the place and hours the Controller specifies, on payment of the prescribed fee. Manufacturers, repairers and dealers must also keep prescribed records (Section 17).

Understand Verification and Stamping of Weights and Measures

A weight or measure is only useful in trade if buyers and sellers can trust it. The Legal Metrology Act, 2009 builds that trust through verification: a check that the instrument is accurate, followed by stamping, the official mark showing it has been checked. The Act extends to the whole of India (Section 1) and came into force on 1 March 2011.

The core duty sits in Section 24(1). It applies to every person who has a weight or measure in his possession, custody or control in circumstances indicating that it is being, or is intended or likely to be, used by him in any transaction or for protection. Such a person must have it verified before putting it to that use. Note the wording: possession alone is not enough. The circumstances must point to use in a transaction or for protection.

Verification is done at the place and during the hours the Controller specifies by general or special order, and the person pays the prescribed fee. For some kinds of weights and measures, the Central Government may prescribe that verification is done through a Government approved Test Centre (Section 24(2)). The Central or State Government notifies such a centre (Section 24(3)). The centre must appoint or engage persons with the prescribed qualifications and experience and collect the prescribed fee (Section 24(4)).

Separate from verification is record keeping. Every manufacturer, repairer or dealer of weight or measure must maintain the prescribed records and registers, and must produce them at inspection to persons authorised under Section 15(1) (Section 17). The details are left to the rules; the State Government can make rules on the registers and records and on the verification fee (Section 53).

The Act also protects the system from abuse. An officer who wilfully verifies or stamps a weight or measure in breach of the Act or rules faces imprisonment up to one year, or fine up to ten thousand rupees, or both (Section 43). Anyone who obstructs an officer, including obstructing entry for inspection, faces imprisonment up to two years, and up to five years for a second or subsequent offence (Section 40).

Key rules to remember

Duty to verify: Possession/custody/control + likely use in transaction or protection → verify BEFORE use (Section 24(1)); Verification is at the place and hours the Controller specifies, on payment of the prescribed fee.
Test Centre route: Central Govt prescribes kinds → verification through Government approved Test Centre (Section 24(2)-(4)); The Central or State Government notifies the centre; it engages qualified persons and collects the prescribed fee.
Records of manufacturers, repairers and dealers: Maintain prescribed records and registers; produce at inspection (Section 17); Production is to persons authorised under Section 15(1).
Exemptions from verification and stamping: Section 55: (a) arms and ammunition factory for Armed Forces; (b) scientific investigation or research; (c) manufactured exclusively for export; The exemption covers only verification and stamping provisions, not the whole Act.
Penalty for wrongful verification by officer: Imprisonment up to 1 year, or fine up to ₹10,000, or both (Section 43); Applies only if the officer acts wilfully.
Penalty for obstruction: Imprisonment up to 2 years; second or subsequent offence up to 5 years (Section 40); Includes obstructing entry into premises for inspection.
Rule-making breach penalty: Rules may provide fine up to ₹5,000 for breach (Sections 52(3) and 53(3)); Applies to the Central and State Governments' rule-making powers respectively.

How to solve Verification and Stamping of Weights and Measures questions

Use this order for any question on verification, stamping or related obligations. It keeps your answer in the ICSI style: provision, facts, conclusion.

1Identify who the person is: a user of weights and measures, a manufacturer, repairer or dealer, or an officer.
2State the relevant provision: Section 24 for verification, Section 17 for records, Section 55 for exemptions, Sections 40 and 43 for penalties.
3Test the facts against the conditions: is the weight or measure in the person's possession, custody or control, and is it likely to be used in a transaction or for protection?
4Check timing: verification must be done before the instrument is put to use.
5Check for exceptions: is it used in an arms factory for the Armed Forces, for research, or made only for export?
6Note who prescribes the details: the Controller for place and hours, the rules for fees and records.
7Write a clear conclusion saying whether the duty applies and what the consequence is.

Quickest way: Four-question check

When to use it: Use when a short case-based question gives you little time.

Is it a weight or measure likely to be used in a transaction or for protection? If no, Section 24 does not bite.
Does a Section 55 exemption apply? If yes, no verification or stamping is required.
If neither, verification is needed before use, on payment of the prescribed fee.
If the person is a manufacturer, repairer or dealer, add the Section 17 records duty.

Common mistakes in Verification and Stamping of Weights and Measures

Saying verification is needed merely because someone possesses a weight or measure.
Students remember 'possession' and skip the rest of Section 24(1).
Fix: Always add the condition: circumstances indicating use or likely use in a transaction or for protection.
Saying verification can be done after use begins.
Students overlook the word 'before' in the section.
Fix: State that verification must be done before putting the weight or measure into such use.
Claiming Section 55 exempts the whole Act for research or export goods.
The heading says 'Act not to apply in certain cases'.
Fix: Write that the exemption applies only to provisions on verification and stamping.
Confusing the Controller's role with the Test Centre's role.
Both are connected with verification.
Fix: The Controller specifies place and hours; Test Centres are used for kinds of weights and measures prescribed by the Central Government.
Mixing up the penalties in Sections 40 and 43.
Both involve officers and imprisonment.
Fix: Section 40 punishes someone obstructing an officer; Section 43 punishes an officer who wilfully verifies wrongly.
Citing the repealed 1976 or 1985 Acts as current law.
Older notes still mention them.
Fix: Cite the Legal Metrology Act, 2009. Mention Section 57 only to explain that earlier notifications and rules continue under the corresponding provisions.

Worked examples

Example 1

Ramesh opens a kirana shop in Pune and buys a new weighing scale to weigh grain sold to customers. He starts using it immediately, intending to get it verified next month. Advise him.

Show the solution

Provision: Section 24(1) of the Legal Metrology Act, 2009 requires every person having a weight or measure in his possession, custody or control in circumstances indicating that it is being or is intended to be used in any transaction to have it verified before putting it into such use.
Facts: The scale is in Ramesh's possession and is used to weigh grain sold to customers, so it is used in a transaction.
Exemptions: None of the Section 55 cases applies. It is not used in an arms factory, for research, or made exclusively for export.
Analysis: Verification must come before use. Using it now and verifying later breaches Section 24(1).
Process: He should have it verified at the place and hours the Controller specifies and pay the prescribed fee.

Answer: Ramesh is wrong. He must have the scale verified before he uses it in any transaction, at the place and hours specified by the Controller, on payment of the prescribed fee. He should stop using it until it is verified.

Example 2

A laboratory in Hyderabad uses precision weights only for scientific research. A staff member says they must be verified and stamped under the Legal Metrology Act, 2009. Is this correct? Would your answer change if the same weights were used to sell chemicals to customers?

Show the solution

Provision: Section 55(b) says the provisions of the Act, so far as they relate to verification and stamping, do not apply to any weight or measure used for scientific investigation or for research.
Facts: The weights are used only for research.
Analysis: Section 55(b) applies, so the verification and stamping requirements do not apply to them.
Change in facts: If the weights are also used in transactions such as selling chemicals, they are no longer used exclusively for research. Section 24(1) then applies to that use.
Limit: Section 55 removes only the verification and stamping provisions, not the rest of the Act.

Answer: The staff member is not correct for research use, because Section 55(b) exempts such weights from verification and stamping. If the weights are used in sales transactions, Section 24(1) would require verification before that use.

Exam tips

Quote Section 24(1) conditions word for word: possession, custody or control; transaction or protection; before use.
Learn the three Section 55 exemptions as a list and write that they relate only to verification and stamping.
For manufacturer, dealer or repairer questions, add Section 17 records and production at inspection.
Keep Sections 40 and 43 apart: who commits the act and the punishment are different.
Finish every case answer with a one-line conclusion that applies the law to the named person.
