How to read this code
29.18 is the four-digit HS heading for acids. To clear customs your destination country extends it to a full 8–10 digit code and assigns the duty rate. India's preferential trade agreements (UAE CEPA, Australia ECTA, and others) can reduce or zero out that duty on many chemicals & allied industries lines — check our import guides for your market.
