Frequently asked questions


How many digits of the HSN code must I show on a GST invoice?


Businesses with aggregate turnover of up to ₹5 crore in the previous year must show at least a 4-digit HSN code on B2B invoices. Businesses with turnover above ₹5 crore must show a 6-digit code on all invoices. The full 8-digit code is used for imports and exports.


What is the difference between an HSN heading and an 8-digit HSN code?


The first 2 digits are the chapter, 4 digits are the heading and 6 digits are the subheading under the international Harmonized System. India adds 2 more digits for a more precise tariff item, giving the 8-digit code used in customs and GST.


What happens if I use the wrong HSN code?


A wrong HSN code can lead to tax being charged at the wrong rate, mismatches in GSTR-1 and the HSN summary, and notices with interest and penalty. If you are unsure about classification, a CA can review it before you file.
