HS code for DDT: 2903.92

Halogenated derivatives of aromatic hydrocarbons, hexachlorobenzene (ISO) and DDT (ISO) (clofenotane (INN), and 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane).

Classification of DDT under HS 2903.92

DDT (ISO), chemically known as 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane, is classified under HS code 290392 when presented as a separate chemically defined compound. This classification is situated within Chapter 29, which covers organic chemicals. Specifically, heading 2903 deals with halogenated derivatives of hydrocarbons. Subheading 290392 was created to monitor and control the trade of this specific persistent organic pollutant (POP) under international environmental conventions. The classification applies to the technical grade chemical or pure substance. It is important to note that this code is for the chemical itself, not for formulated pesticides or mixtures containing DDT, which are classified elsewhere in the tariff schedule based on their preparation and packaging.

Codes often confused with 2903.92

Common mistake. DDT is often misclassified under 380891 if it is already mixed with carriers or solvents for use as an insecticide. It may also be confused with other halogenated aromatic hydrocarbons under 290399. However, because DDT is specifically named in 290392, that code takes precedence over more general subheadings according to GRI 1.

Top exporters and importers of HS 290392 (the code used for DDT), 2025

In 2025, the largest exporter of HS 290392 (the code used for DDT) in UN Comtrade data was India, with 62% of world exports; the largest importer in UN Comtrade data was France, with 63% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
