What HSN code and GST rate apply to my product, and where do I look it up?
The short answer
Every product maps to an HSN code that fixes which GST slab it falls in (commonly 0 / 5 / 12 / 18 / 28%, slabs and rates get revised periodically, so always check the current rate). Find yours for free by typing the product description into the ClearTax or official GST-portal HSN finder. You must print the HSN on your invoices and report it in GSTR-1; how many digits you need scales with your turnover.

Why we picked it
A free search tool where you type your product name and get the HSN code and its GST rate instantly, the quickest way to classify a new SKU before you list it.
Why we picked it
The authoritative government HSN/SAC lookup, worth cross-checking against a third-party finder when a rate is ambiguous. Listed as canonical; the portal blocks automated fetches so we couldn't machine-verify the exact deep link.
