HS Code 2903.82 – Halogenated derivatives of cyclanic, cyclenic or cycloterpenic hydrocarbons; aldrin (ISO), chlordane (ISO), and heptachlor (ISO)

HS code 2903.82 is the 6-digit subheading for halogenated derivatives of cyclanic, cyclenic or cycloterpenic hydrocarbons, aldrin (ISO), chlordane (ISO), and heptachlor (ISO). It is used for aldrin, chlordane, heptachlor, dieldrin and endrin.

What HS 2903.82 covers

This HS code covers specific halogenated derivatives of cyclanic, cyclenic, or cycloterpenic hydrocarbons: aldrin (ISO), chlordane (ISO), and heptachlor (ISO). These are notorious Persistent Organic Pollutants (POPs) that were widely used as insecticides in agriculture and for termite control due to their effectiveness and persistence. However, their severe environmental and health impacts, including bioaccumulation and long-range transport, led to their global ban under the Stockholm Convention. As a result, international trade in newly produced aldrin, chlordane, and heptachlor is virtually non-existent. Any remaining trade is strictly controlled and limited to the environmentally sound management, storage, and destruction of existing stockpiles, often facilitated by international aid organizations or specialized waste disposal companies. Importers and exporters are typically government entities or licensed hazardous waste handlers.

Codes often confused with 2903.82

Common mistake. Often confused with other organochlorine pesticides like DDT (2903.92) or HCH (2903.81) due to similar chemical class and regulatory status 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).
