GST & Legal Metrology: A Regulatory Convergence
In India’s regulatory landscape, businesses must understand how GST and Legal Metrology intersect. This page explains the overlap and offers actionable insights for businesses dealing with pre-packaged goods or weight/measure-based transactions.
1.1 GST
- Comprehensive indirect tax system under GST Act, 2017
- Focuses on value, classification, returns, and tax collection
1.2 Legal Metrology
- Regulates weight, measure, and labeling accuracy (LM Act, 2009)
- Mandates declarations like MRP, net quantity, etc. on packages
- Pre-packaged Commodities: Must comply with both GST and LM declarations
- Definition Variance: LM focuses on packaging; GST focuses on tax liability
- Labeling & Invoicing: Packaging labels vs GST invoices – mismatches can lead to dual penalties
- Imports: Requires both LM registration and IGST compliance
- Valuation: MRP under LM may differ from transaction value under GST
