Frequently Asked Questions

What is an HSN code in GST?
HSN stands for Harmonized System of Nomenclature, a 6-to-8 digit international code system developed by the World Customs Organization. In India's GST system, it is mandatory for classifying goods on tax invoices. Businesses above ₹5 Crore turnover must use 6-digit codes; exporters must always use 8-digit codes.
What is the difference between HSN and SAC codes?
HSN codes are used for goods (physical products, classified under chapters 1-98 of the Customs Tariff), while SAC (Services Accounting Code) codes are used for services (all SAC codes start with "99"). Both appear in the same field on a GST invoice. A single invoice can have both if it includes both goods and services.
What happens if I use a wrong HSN code on my invoice?
Using a wrong HSN code can lead to: (1) ITC mismatch in your buyer's GSTR-2B, causing their ITC to be blocked, (2) Scrutiny notices from the GST department, (3) Differential tax demand if the wrong code carries a lower rate than the correct one, and (4) Penalties under Section 125 of the CGST Act (up to ₹25,000).
