Looking for the GST rate and HSN code for diamonds in India? This guide explains the slab, the HSN code, and the input-tax-credit angle.
GST rate on diamonds
GST in India is a destination-based tax split into CGST and SGST for sales within a state and IGST for inter-state sales. Following the rate overhaul effective 22 September 2025, most goods and services sit in a simplified two-slab structure (5% and 18%), with a higher 40% rate reserved for a short list of luxury and "sin" items, and essentials kept exempt.
Cut and polished diamonds have a low, specific rate. Rates change at GST Council meetings, so always confirm the current figure for your exact HSN or SAC code on the CBIC rate finder or the GST portal before you print it on an invoice.
Finding the right HSN code for diamonds
Every product has a Harmonised System of Nomenclature (HSN) code that decides its GST rate. Search your product description on the CBIC HSN/rate finder or the GST portal, match the 4-, 6- or 8-digit code to what you actually sell, and use that same code on every invoice so your returns stay consistent.
- Use the correct HSN code for diamonds on every tax invoice.
- Charge CGST + SGST within your state and IGST for inter-state sales.
- Keep the rate consistent between your GSTR-1 and GSTR-3B.
- Confirm the current rate before each price change — slabs are revised at GST Council meetings.
Input tax credit angle
If you buy diamonds for business use and resupply it, you can usually claim input tax credit on your purchase, provided the invoice appears in your GSTR-2B and all the standard conditions are met. Credit is blocked where the purchase is for personal use or falls under the Section 17(5) blocked-credit list.
