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.
