HS Code 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)

HS code 2903.92 is the 6-digit subheading for halogenated derivatives of aromatic hydrocarbons, hexachlorobenzene (ISO) and DDT (ISO) (clofenotane (INN), and 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane). It is used for DDT, hexachlorobenzene, dicofol (related to DDT structure), HCB and 1,1,1-Trichloro-2,2-bis(p-chlorophenyl)ethane.

What HS 2903.92 covers

This HS code specifically covers two highly significant halogenated derivatives of aromatic hydrocarbons: hexachlorobenzene (HCB) and DDT (clofenotane, 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane). Both are classified as Persistent Organic Pollutants (POPs) under the Stockholm Convention due to their extreme persistence, bioaccumulation, and toxicity. HCB was historically used as a fungicide, while DDT was a widely used insecticide, particularly for vector control. Their production, use, and trade are now severely restricted or banned globally. Any current trade is highly regulated, primarily involving the environmentally sound management and destruction of existing stockpiles. Limited exceptions exist for DDT in vector control for public health purposes in specific regions, under strict WHO guidelines. Importers and exporters are typically government agencies, international organizations, or specialized hazardous waste management companies.

Codes often confused with 2903.92

Common mistake. Often confused with other organochlorine pesticides like aldrin or chlordane (2903.82) or HCH (2903.81) due to similar regulatory status and chemical class as POPs.

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).
