Product classification
HS code for Endrin: 2910.50
Epoxides, epoxyalcohols, epoxyphenols and epoxyethers, with a three-membered ring and their halogenated, sulphonated, nitrated or nitrosated derivatives, endrin (ISO).
Classification of endrin under HS 2910.50
Endrin is classified under HS code 2910.50, which specifically covers epoxides, epoxyalcohols, epoxyphenols, and epoxyethers with a three-membered ring, including their halogenated, sulphonated, nitrated, or nitrosated derivatives. As an organochlorine compound, Endrin is a stereoisomer of dieldrin and is chemically defined as an epoxide. The classification follows the General Rules of Interpretation (GRI) 1 and 6, where the product is identified by its specific chemical structure. Chapter 29 of the Harmonized System deals with organic chemicals, and heading 2910 is reserved for compounds containing an epoxide group. Because Endrin is specifically named in the subheading 2910.50, it takes precedence over more general chemical classifications. This classification applies to the pure chemical or technical grade substance. If the product were formulated as a finished insecticide for retail sale, the classification would shift to Chapter 38, but as a raw chemical substance, 2910.50 is the correct designation.

Codes often confused with 2910.50
Common mistake. Endrin is frequently misclassified under HS code 2903, which covers halogenated derivatives of hydrocarbons. While endrin is indeed halogenated, the presence of the epoxide ring (a cyclic ether with three atoms) dictates that it must be classified under heading 2910. Another common error is placing it under HS code 3808.91, which covers insecticides. While endrin was historically used as an insecticide, heading 3808 is only appropriate if the product is put up in forms or packings for retail sale or as preparations. Pure chemical endrin remains in Chapter 29.
Top exporters and importers of HS 291050 (the code used for endrin), 2025
In 2025, the largest exporter of HS 291050 (the code used for endrin) in UN Comtrade data was the United States, with 91% of world exports; the largest importer in UN Comtrade data was Spain, with 40% of world imports.

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).
