HS 29.31 covers Other organo-inorganic compounds. At the six-digit line it separates organo-inorganic compounds, non-halogenated organo-phosphorous derivatives and halogenated organo-phosphorous derivatives, among others — each a distinct duty line shown below. Organic chemicals are a major Indian export, anchored by the country's strength in bulk drugs and intermediates. India exported $183.5M under this code worldwide in 2024, about 0.9% of all Chapter 29 exports, ranking #27 of 42 lines in its chapter (UN Comtrade).

How to read this code

29.31 is the four-digit HS heading for other organo-inorganic compounds. 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.
