Product classification
HS code for DDT mixtures: 3824.84
Chemical products, mixtures and preparations, containing aldrin, camphechlor (toxaphene), chlordane, chlordecone, DDT (chlorfenotane, 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane), dieldrin, endosulfan, endrin, heptachlor or mirex.
Classification of DDT mixtures under HS 3824.84
HS code 3824.84 is designated for chemical products and preparations containing DDT (1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane). This classification falls under Chapter 38, which covers miscellaneous chemical products. Specifically, heading 3824 is a residual heading for chemical products and preparations of the chemical or allied industries not elsewhere specified or included. Subheading 3824.84 was introduced to facilitate the monitoring and control of substances regulated under the Stockholm Convention on Persistent Organic Pollutants (POPs). Unlike pure DDT, which is classified in Chapter 29 as a separate chemically defined organic compound, mixtures containing DDT—even in small concentrations—are directed to this specific subheading. This ensures that environmental and safety regulations are applied correctly during cross-border trade of these hazardous mixtures, regardless of whether they are intended for agricultural, public health, or research purposes.

Codes often confused with 3824.84
Common mistake. Pure DDT (chemically defined) is classified under 2903.92, not 3824.84. If the DDT mixture is put up in forms or packings for retail sale as an insecticide, it may be classified under heading 3808.91. However, the specific subheadings for POPs in 3824 often take precedence for environmental monitoring. Confusion also occurs with 3824.81 through 3824.88, which cover other specific hazardous mixtures like those containing oxirane or PCBs.

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).
