Inorganic chemicals; organic and inorganic compounds of precious metals; of rare earth metals, of radio-active elements and of isotopes
Chapter 28 of the Harmonised System covers Inorganic chemicals; organic and inorganic compounds of precious metals; of rare earth metals, of radio-active elements and of isotopes. It groups 50 four-digit headings used worldwide to classify these goods for customs and duty.

How to read this code
28 is the two-digit HS chapter. Your destination country extends it to 8–10 digits and assigns the duty rate. India's preferential trade agreements (UAE CEPA, Australia ECTA, and others) can reduce or zero out that duty for many goods — check our import guides for your market.
