HS Code 2910.40 – Epoxides, epoxyalcohols, epoxyphenols and epoxyethers; with a three-membered ring and their halogenated, sulphonated, nitrated or nitrosated derivatives, dieldrin (ISO, INN)
HS code 2910.40 is the 6-digit subheading for epoxides, epoxyalcohols, epoxyphenols and epoxyethers, with a three-membered ring and their halogenated, sulphonated, nitrated or nitrosated derivatives, dieldrin (ISO, INN). It is used for dieldrin analytical standard, environmental testing kits and historical pesticide samples.
What HS 2910.40 covers
This HS code pertains to dieldrin, an organochlorine insecticide that was historically widely used but is now largely banned or severely restricted globally due to its persistence in the environment and high toxicity. Its trade is minimal, primarily limited to small quantities for analytical reference standards, research purposes, or for environmentally sound destruction under international conventions like the Stockholm Convention on Persistent Organic Pollutants. There are virtually no legitimate commercial imports or exports for its original pesticidal use. Any movement of dieldrin is subject to stringent international controls and national regulations, reflecting its status as a hazardous substance with significant environmental and health concerns.

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. 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).
