Understanding HSN and SAC Codes in GST Invoicing

HSN (Harmonized System of Nomenclature) is an internationally recognized 6-digit classification system developed by the World Customs Organization (WCO). In India, the Central Board of Indirect Taxes and Customs (CBIC) added 2 more digits to create an 8-digit classification for greater goods granularity. SAC (Services Accounting Code) is similarly used to classify all taxable services under GST.

Mandatory HSN Rules for Indian Businesses:

  • Turnover up to ₹5 Crores: Mandatory 4-digit HSN code on all B2B tax invoices.
  • Turnover above ₹5 Crores: Mandatory 6-digit HSN code on both B2B and B2C invoices.
  • Export and Import: Mandatory 8-digit HSN code irrespective of turnover.
