What is HSN and SAC?
HSN (Harmonised System of Nomenclature)
HSN is a multi-purpose international product nomenclature developed by the World Customs Organisation (WCO). It is used to systematically classify goods for GST billing in India. It is usually 2, 4, 6 or 8 digits.
SAC (Services Accounting Code)
SAC is a system developed by the Central Board of Indirect Taxes and Customs (CBIC) to classify all services for GST invoicing. All SAC codes start with the number 99.
Understanding HSN and SAC Classifications
Classification of goods and services is essential under the GST act to ensure appropriate tax rates are applied. Using correct **HSN (Harmonised System of Nomenclature)** and **SAC (Services Accounting Code)** numbers on invoices minimizes reporting discrepancies and simplifies tax returns.
Sellers must select codes corresponding to their business sector and supply details to prevent verification failures on the e-way bill and GST portal.
