The rate depends on what the goods are: the notification gives a different rate to different descriptions. Match your goods to a description in the table below. In force on 7 Nov 2026.
Each row is an entry of a CBIC rate notification that names this heading, a code inside it or its whole chapter, in the notification's own words. Goods take the rate of the entry whose description fits them. GST is CGST plus SGST (or UTGST) in equal halves on a sale within a State, or IGST at the full rate on a sale between States.
