Introduction

The Legal Metrology Act, 2009 (LMA) governs measurements, weighing, and packaging in trade to prevent consumer fraud. Enforced by the Department of Legal Metrology across states, it mandates accurate weights, pre-packed labels, and verified instruments. From kirana stores to Flipkart warehouses, non-compliance invites ₹2,000–₹1 crore fines or 1-year imprisonment. Over 3.5 lakh verifications and 1.2 lakh prosecutions occurred in 2024 alone.

Historical Development

Pre-1976: Standards of Weights & Measures Act, 1976 allowed dual systems (metric + imperial). 1976–2009: Uniform metric system enforced; state-level gaps persisted. 2009: LMA 2009 replaced 1976 Act with centralized rules, e-commerce coverage, and compoundable offences. 2011: Legal Metrology (Packaged Commodities) Rules, 2011 introduced MRP, net quantity, and declaration mandates. 2017–2025: Online verification, QR code declarations, and dark pattern bans added via amendments.
