HS code · 6-digit subheading
HS Code 2903.99 – Halogenated derivatives of aromatic hydrocarbons; n.e.c. in item no. 2903.91, 2903.92, 2903.93 and 2903.94
HS code 2903.99 is the 6-digit subheading for halogenated derivatives of aromatic hydrocarbons, n.e.c. in item no. 2903.91, 2903.92, 2903.93 and 2903.94. It is used for bromobenzene, iodobenzene, fluorobenzene, tetrachlorobenzene and bromochlorobenzene.
What HS 2903.99 covers
This 'basket' HS code covers other halogenated derivatives of aromatic hydrocarbons not specifically enumerated in subheadings 2903.91, 2903.92, 2903.93, or 2903.94. This category includes a wide array of specialty chemicals that serve as crucial intermediates in the synthesis of pharmaceuticals, agrochemicals, dyes, polymers, and electronic materials. These compounds often possess unique properties due to the specific halogen and aromatic structure, making them valuable for niche applications. Trade in these substances is typically conducted by specialized chemical manufacturers and distributors, catering to industries requiring high-purity or custom-synthesized compounds. The trade flows are global, connecting countries with advanced chemical industries and strong research and development capabilities.

Codes often confused with 2903.99
Common mistake. Can be easily confused with the specifically enumerated aromatic halogenated compounds (2903.91, 2903.92, 2903.93, 2903.94) or with non-halogenated aromatic compounds (2902.x) if the halogenation is overlooked.
Top exporters and importers of HS code 290399, 2025
In 2025, the largest exporter of HS code 290399 in UN Comtrade data was China, with 46% of world exports; the largest importer in UN Comtrade data was India, with 15% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
