Frequently Asked Questions
HSN (Harmonised System of Nomenclature) is an internationally standardised system of classifying goods, adopted by India for GST. Every product sold must carry an HSN code on the tax invoice. Services use SAC (Services Accounting Code) instead.
Yes — HSN codes are mandatory on B2B invoices for all registered taxpayers. Businesses with annual turnover above ₹5 crore must mention 6-digit HSN codes; above ₹1.5 crore must mention 4-digit codes; below ₹1.5 crore must mention at least 2-digit chapter codes.
HSN codes are used for goods (products). SAC codes are used for services. Both serve the same purpose — identifying the correct GST rate. SAC codes all begin with 99, while HSN codes cover chapters 1 to 98.
Yes. Incorrect HSN classification is one of the most common reasons for GST demand notices. If you classify a 12% item as 5%, the department can raise a demand for the differential tax plus interest and penalty. Always verify before using on invoices.
HSN codes can be 2, 4, 6, or 8 digits. More digits mean more specificity. For GST invoice purposes, 4 or 6 digits are most commonly used. The 8-digit code is used for import/export under the Customs Tariff Act.
Yes. The classifier searches both HSN codes (goods) and SAC codes (services). Service descriptions like "software", "consulting", "restaurant", "transport", and "insurance" will return the appropriate SAC codes.
