About HSN Chapter 25 (Salt; Sulphur; Earths and Stone; Plastering Materials, Lime and Cement)

Chapter 25 of the Harmonized System of Nomenclature covers salt; sulphur; earths and stone; plastering materials, lime and cement. Every product imported, exported or supplied under GST is classified under a 6-digit HSN code derived from this chapter structure — the first two digits (25) identify the chapter, the next two the heading, and the last two the specific product.

Use the correct 6-digit code on GST invoices: taxpayers with turnover above ₹5 crore must quote 6 digits, and those between ₹1.5 crore and ₹5 crore must quote at least 4 digits. If you are unsure which heading your product falls under, our experts can confirm the right classification for you.
