HSN codes for steel

The 4- and 6-digit HSN code for every material we supply, and the thickness and width rules that decide which one applies. GST on all of them is 18%.

Three rules that decide the code

1How many digits your invoice needs: Turnover up to ₹5 crore in the last financial year: 4 digits on B2B invoices. Above ₹5 crore: 6 digits on every invoice.
2Width: 600 mm is the line: Flat steel 600 mm wide or more is 7208, 7209 or 7210. Slit coil and strip under 600 mm wide moves to 7211 or 7212.
3Coil or cut, and thickness: The same steel takes a different 6-digit code as a coil or as cut sheets, and again by thickness band.

Once a coil is slit narrower than 600 mm, it is billed under the narrow-strip headings instead.

If you send us your own coil to slit or cut, that is job work — a service billed under a SAC code, not an HSN code.

The first 6 digits are the same in India's Customs Tariff and worldwide. The full 8-digit code is needed for imports and exports, not on a GST invoice.
Codes as of October 2026. For your own invoices and returns, confirm with your CA.

Four fields are enough for a first price. Add sizes if you have them.
