Product classification
HS code for Chlordane: 2903.82
Halogenated derivatives of cyclanic, cyclenic or cycloterpenic hydrocarbons, aldrin (ISO), chlordane (ISO), and heptachlor (ISO).
Classification of chlordane under HS 2903.82
Chlordane is classified under HS code 2903.82. This classification is based on Chapter 29 of the Harmonized System, which encompasses organic chemicals. Heading 2903 specifically covers halogenated derivatives of hydrocarbons. Subheading 2903.82 is a specialized category for halogenated derivatives of cyclanic, cyclenic, or cycloterpenic hydrocarbons, specifically naming aldrin (ISO), chlordane (ISO), and heptachlor (ISO). Chlordane is an organochlorine compound that was historically used as a pesticide. Under GRI 1, the specific mention of "chlordane" in the subheading text makes 2903.82 the mandatory code for the technical grade chemical. This classification is strictly monitored due to the substance's status under the Stockholm Convention on Persistent Organic Pollutants (POPs). The classification remains in 2903.82 as long as the product is a separate chemically defined compound, regardless of its intended use as an intermediate or a precursor.

Codes often confused with 2903.82
Common mistake. Chlordane is frequently misclassified under HS code 3808.91, which covers insecticides. The distinction lies in the formulation: 2903.82 is for the pure or technical chemical, whereas 3808.91 is for products put up in forms or packings for retail sale or as preparations (e.g., liquids, powders, or aerosols). Another common error is using 2903.89 for "other" halogenated derivatives, but since chlordane is explicitly named in 2903.82, the latter must be used according to GRI 6.
Top exporters and importers of HS 290382 (the code used for chlordane), 2025
In 2025, the largest exporter of HS 290382 (the code used for chlordane) in UN Comtrade data was the United States, with 61% of world exports; the largest importer in UN Comtrade data was Taiwan, with about 21% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).

Questions about chlordane
What is the HS code for Chlordane?
The HS code for Chlordane is 290382 (Halogenated derivatives of cyclanic, cyclenic or cycloterpenic hydrocarbons; aldrin (ISO), chlordane (ISO), and heptachlor (ISO)). The HS code for technical or pure chlordane is 2903.82.
How do I classify Chlordane for customs?
Chlordane is classified under HS code 290382 — Halogenated derivatives of cyclanic, cyclenic or cycloterpenic hydrocarbons; aldrin (ISO), chlordane (ISO), and heptachlor (ISO). This is a 6-digit subheading level code.
Is a permit required to import chlordane under this code?
Yes, because chlordane is a restricted persistent organic pollutant, most countries require specific environmental permits and adherence to the Rotterdam and Stockholm Conventions for its movement.
