HS code for Dichlorobenzene: 2903.91
Halogenated derivatives of aromatic hydrocarbons, chlorobenzene, o-dichlorobenzene, and p-dichlorobenzene.
Classification of dichlorobenzene under HS 2903.91
Dichlorobenzene is classified under HS code 2903.91, which pertains to halogenated derivatives of aromatic hydrocarbons. Chapter 29 covers organic chemicals, and heading 2903 specifically addresses halogenated derivatives of hydrocarbons. Within the aromatic subgroup, subheading 2903.91 explicitly lists chlorobenzene, o-dichlorobenzene, and p-dichlorobenzene. These are aromatic rings where hydrogen atoms have been substituted with chlorine. The classification is based on the chemical structure of the molecule. Whether the isomer is ortho (1,2-dichlorobenzene) or para (1,4-dichlorobenzene), it is captured under this specific subheading. This code is intended for the chemical in its pure or commercially pure form, often used as a precursor in chemical synthesis, as a solvent, or as a fumigant. The precise chemical identification ensures that these substances are monitored correctly for environmental and safety regulations during international transit.

Codes often confused with 2903.91
Common mistake. A common misclassification occurs when para-dichlorobenzene is sold as mothballs or deodorants in retail packaging. In such instances, it should be classified under HS code 3808.91 (insecticides) or 3307.49 (room deodorizers). Another error is using 2903.99 for m-dichlorobenzene, which is technically correct for the meta isomer, but 2903.91 is strictly for the ortho and para isomers and monochlorobenzene.
Top exporters and importers of HS 290391 (the code used for dichlorobenzene), 2025
In 2025, the largest exporter of HS 290391 (the code used for dichlorobenzene) in UN Comtrade data was Germany, with 35% of world exports; the largest importer in UN Comtrade data was the United States, with 35% of world imports. Mexico reports $578M of its heading 2903 imports without product detail (confidential), so it may also belong among the top importers.

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).

Questions about dichlorobenzene
What is the HS code for Dichlorobenzene?
The HS code for Dichlorobenzene is 290391 (Halogenated derivatives of aromatic hydrocarbons; chlorobenzene, o-dichlorobenzene, and p-dichlorobenzene). The HS code for o-dichlorobenzene and p-dichlorobenzene is 2903.91, as they are specifically named halogenated derivatives of aromatic hydrocarbons.
How do I classify Dichlorobenzene for customs?
Dichlorobenzene is classified under HS code 290391 — Halogenated derivatives of aromatic hydrocarbons; chlorobenzene, o-dichlorobenzene, and p-dichlorobenzene. This is a 6-digit subheading level code.
Is p-dichlorobenzene in mothball form classified here?
No, if it is prepared as mothballs for retail sale, it is classified as an insecticide under HS code 3808.91.
Which countries are the top exporters of dichlorobenzene (HS 290391)?
In 2025, the top exporters of HS 290391 (the code used for dichlorobenzene) in UN Comtrade data were Germany ($48M, 35% of world exports), India ($43M) and China ($22M). World exports came to about $137M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of dichlorobenzene (HS 290391)?
In 2025, the top importers of HS 290391 (the code used for dichlorobenzene) in UN Comtrade data were the United States ($57M, 35% of world imports), Japan ($38M) and Indonesia ($7.5M). World imports came to about $164M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Mexico reports $578M of its heading 2903 imports without product detail (confidential), so it may also belong among the top importers.
Is the HS code for Dichlorobenzene the same in all countries?
The base HS code 290391 for Dichlorobenzene is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for dichlorobenzene in Brazil?
Brazil splits HS 290391 into 3 NCM codes, so the right one for dichlorobenzene depends on the product's details: 2903.91.10 (Chlorobenzene), 2903.91.20 (o-Dichlorobenzene), 2903.91.30 (p-Dichlorobenzene).
