In 2026, businesses dealing with weighing machines, packaged goods and product labelling need to pay close attention to Legal Metrology compliance. Whether you manufacture, import, pack or sell pre-packaged commodities, your business may be subject to the Legal Metrology Act, 2009 and the Legal Metrology (Packaged Commodities) Rules, 2011.
Legal Metrology compliance is not limited to completing a registration or obtaining a certificate. Depending on the nature of your business, you may also need to meet requirements related to weighing and measuring instruments, product declarations, packaging, labelling and periodic verification. Non-compliance can result in inspection notices, penalties and, in certain situations, seizure of goods by the concerned authorities.
Many Legal Metrology registration and licensing procedures are now handled through online state or central government portals. While online filing can make the process more convenient, incorrect information, missing documents or improper declarations can still result in queries and delays.
This guide explains the key aspects of Legal Metrology compliance, including what an LMPC certificate is, which businesses need it, the documents and requirements involved, the applicable cost and how the registration process works.
What is an LMPC Certificate?
LMPC stands for Legal Metrology Packaged Commodities certificate. It is a mandatory registration under Rule 27 of the Legal Metrology (Packaged Commodities) Rules, 2011, required for any business that manufactures, packs, or imports pre-packaged commodities meant for sale to end consumers.
"Pre-packaged commodities" means any product that is packaged before the consumer buys it — from packaged food and cosmetics to electronics and consumer goods. If your business falls into any of these categories, you legally need an LMPC certificate:
- Manufacturers who pack their own products before sale
- Packers who package goods on behalf of another brand
- Importers bringing pre-packaged goods into India
Importers must apply for LMPC registration within 90 days of commencing import operations — this is a hard compliance deadline, and late filing attracts a late fee in addition to the registration fee.
LMPC Certificate vs. Weights & Measures Licenses
These are often confused, but they are two different registrations under the same Act:
| LMPC Certificate | Weights & Measures License | |
|---|---|---|
| Governs | Labelling & registration of pre-packaged goods | Accuracy & certification of measuring instruments |
| Who needs it | Manufacturers, packers, importers of packaged goods | Businesses using weighing/measuring equipment (shops, factories, dealers) |
| Applied under | Rule 27, LMPC Rules 2011 | Legal Metrology (General) Rules, 2011 |
| License types | Manufacturer / Packer / Importer registration | Manufacturer's, Dealer's, Repairer's, Importer's License |
A business may need both, depending on what it does — for example, a packaged-food manufacturer using its own weighing equipment would need an LMPC certificate for the packaging and a Manufacturer's License for the weighing instruments.
