Compliance Guide: Legal Metrology Act 2009 for Businesses in India

What the Legal Metrology Act 2009 Covers

The Legal Metrology Act, 2009, enforces standards for weights and measures and regulates trade in goods sold by weight, measure, or number. In force since March 1, 2011, it replaced the earlier Standards of Weights and Measures Act, 1976, and its Enforcement Act, 1985. Businesses handling pre-packaged commodities, weighing equipment, or measuring instruments must comply to avoid the penalties detailed below. Enforcement has intensified in recent years, particularly against importers and e-commerce sellers.

Rules Framework Under the Act

• Legal Metrology (General) Rules, 2011
• Legal Metrology (Packaged Commodities) Rules, 2011
• Legal Metrology Numeration Rules, 2011
• Indian Institute of Legal Metrology Rules, 2011
• Legal Metrology (Approval of Models) Rules, 2011
• Legal Metrology (Government Approved Test Centre) Rules, 2013

Who Needs to Comply

Manufacturing, Packing, or Importing Pre-Packaged Commodities

Governed by the Legal Metrology (Packaged Commodities) Rules, 2011. A pre-packaged commodity is any commodity placed in a package with a predetermined quantity, sealed or not, without the purchaser present.

Manufacturer

Anyone who manufactures a packaged commodity, or marks a commodity not manufactured by them as their own.

Importer

Any person or firm bringing commodities into India from outside India for sale, distribution, or delivery.

Packer

Any person or firm pre-packing a commodity into units for retail or wholesale sale.

Manufacturing, Selling, Repairing, or Importing Weighing and Measuring Equipment

Governed by the Legal Metrology (Approval of Models) Rules, 2011. Manufacturers and importers of weighing/measuring equipment must obtain government approval before manufacturing or importing.

Manufacturer

Anyone who manufactures or assembles a weight or measure, or marks one not made by them as their own.

Importer

Any person or firm bringing weighing/measuring equipment into India from outside India.

Dealer

Anyone buying, selling, supplying, or distributing weights and measures, directly or indirectly, including manufacturers and importers acting in that capacity.

Core Compliance Obligations

Approvals

Anyone intending to manufacture or import a weight or measure must register with the concerned Director and obtain model approval from the competent authority at least one month prior to manufacture or import.

Licensing Requirements

Every manufacturer, repairer, or dealer of weights and measures must obtain a license from the Controller of Legal Metrology under Rule 11(1) of the Legal Metrology (General) Rules, 2011:

• Manufacturer — Form LM-1
• Repairer — Form LR-1
• Dealer — Form LD-1

Registration for Manufacturers, Packers, and Importers of Commodities

Anyone pre-packing or importing a commodity for sale, distribution, or delivery must register under the Legal Metrology (Packaged Commodities) Rules, 2011.

Mandatory Declarations

• Name and address of the manufacturer, packer, or importer
• Country of origin
• Common or generic name of the commodity
• Net quantity
• Retail sale price (MRP, inclusive of taxes)
• Month and year of manufacture, packing, or import, plus expiry date
• Size/dimension where relevant

Verification and Stamping

Every user of a weight, measure, or measuring instrument must have it verified by the Controller at a government-approved test center prior to use.

2025–2026 Regulatory Updates

The Legal Metrology (Packaged Commodities) Rules, 2011, have been amended three times in the past nine months. Businesses relying on pre-2025 guidance are working from an outdated compliance picture:

• Medical devices carve-out (October 2025): Packages containing medical devices now follow the Medical Devices Rules, 2017, for declaration font size and dimensional standards instead of the standard Legal Metrology requirements; Rule 33 relaxations no longer apply where Medical Devices Rules govern.
• Pan masala exemption (effective February 1, 2026): A proviso under Rule 26(a) exempts pan masala from that clause’s requirements.
• E-commerce Country-of-Origin filters (effective July 1, 2026, live now): New Rule 6(10A) requires e-commerce entities selling imported products to make those listings discoverable through searchable, sortable Country-of-Origin filters not just static disclosure. This applies to marketplaces, inventory-based retailers, D2C importers, and cross-border sellers. Further provisions phase in from July 1, 2027.

Penalties for Non-Compliance

Sections 25 to 47 of the Act prescribe fines and imprisonment for default:

• Non-standard weight or measure: penalty up to INR 25,000; imprisonment up to 6 months for repeat offenses
• Manufacture or sale of non-standard weight or measure: penalty up to INR 25,000; imprisonment up to 3 years for repeat offenses
• Selling non-standard packages: penalty up to INR 50,000 (extendable to INR 1 lakh); imprisonment up to 1 year for repeat offenses
• Non-registration as an importer: penalty up to INR 25,000; imprisonment up to 6 months for repeat offenses
• Manufacturing without a license: penalty up to INR 25,000; imprisonment up to 1 year for repeat offenses

Enforcement scrutiny has increased in recent years, particularly against importers and — following Rule 6(10A) — e-commerce platforms, where non-compliance is objectively verifiable through platform testing and carries high enforcement visibility.
