HS Code 2903.91 – Halogenated derivatives of aromatic hydrocarbons; chlorobenzene, o-dichlorobenzene, and p-dichlorobenzene
HS code 2903.91 is the 6-digit subheading for halogenated derivatives of aromatic hydrocarbons, chlorobenzene, o-dichlorobenzene, and p-dichlorobenzene. It is used for chlorobenzene, ortho-dichlorobenzene, para-dichlorobenzene, monochlorobenzene and 1,2-Dichlorobenzene.
What HS 2903.91 covers
This HS code covers three fundamental halogenated derivatives of aromatic hydrocarbons: chlorobenzene, o-dichlorobenzene, and p-dichlorobenzene. These compounds are vital industrial intermediates with widespread applications. Chlorobenzene is used in the production of pesticides, dyes, and as a solvent. Ortho-dichlorobenzene serves as a solvent, a chemical intermediate, and in pest control. Para-dichlorobenzene is well-known for its use in mothballs, air fresheners, and as an intermediate for polymers and dyes. Trade in these chemicals is significant and global, driven by the chemical, pharmaceutical, and agricultural industries. Major chemical producers and distributors are key players, with substantial volumes moving between countries with large manufacturing sectors. Environmental regulations regarding their use and discharge are important considerations for traders.

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).
