Product classification
HS code for Aldrin: 2903.82
Halogenated derivatives of cyclanic, cyclenic or cycloterpenic hydrocarbons, aldrin (ISO), chlordane (ISO), and heptachlor (ISO).
Classification of aldrin under HS 2903.82
Aldrin is classified under Harmonized System (HS) code 2903.82 due to its specific chemical composition and classification as a halogenated derivative of cyclanic hydrocarbons. This particular subheading is dedicated to a defined group of such compounds, explicitly listing aldrin (ISO), chlordane (ISO), and heptachlor (ISO). The classification is based on the substance's molecular structure, which includes halogen atoms attached to a cyclanic hydrocarbon framework, aligning precisely with the descriptive text of the HS code. This ensures that aldrin, as a distinct chemical entity, is categorized accurately within the organic chemicals section of the Harmonized System.
- Covers
- Aldrin (ISO)
- Chlordane (ISO)
- Heptachlor (ISO)
- Other halogenated derivatives of cyclanic, cyclenic, or cycloterpenic hydrocarbons specifically identified under this heading.
- Also under 2903.82
- Shell Aldrin (historical)
- Velsicol Chlordane (historical)
- Heptachlor (as a standalone pesticide)
Codes often confused with 2903.82
Common mistake. Aldrin is sometimes confused with other halogenated hydrocarbons, particularly those falling under HS code 2903.89, which covers "Other" halogenated derivatives of cyclanic, cyclenic, or cycloterpenic hydrocarbons not specifically enumerated elsewhere. The key distinction for 2903.82 is the explicit mention of aldrin, chlordane, and heptachlor. Another potential misclassification could be with pesticides or insecticides in Chapter 38 (e.g., 3808), especially since aldrin has historical use as a pesticide. However, Chapter 29 is reserved for distinct, pure organic chemical compounds, whereas Chapter 38 covers formulated preparations or products with specific functions. Therefore, pure aldrin, as a chemical substance, remains in 2903.82, while a pesticide formulation containing aldrin would be classified in Chapter 38.
Top exporters and importers of HS 290382 (the code used for aldrin), 2025
In 2025, the largest exporter of HS 290382 (the code used for aldrin) 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.
Figures cover everything classified under HS 290382, not only aldrin.

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 aldrin
What is the HS code for Aldrin?
The HS code for Aldrin is 290382 (Halogenated derivatives of cyclanic, cyclenic or cycloterpenic hydrocarbons; aldrin (ISO), chlordane (ISO), and heptachlor (ISO)). The HS code for Aldrin is 2903.82, which specifically covers halogenated derivatives of cyclanic, cyclenic, or cycloterpenic hydrocarbons, including aldrin (ISO), chlordane (ISO), and heptachlor (ISO).
How do I classify Aldrin for customs?
Aldrin is classified under HS code 290382 โ Halogenated derivatives of cyclanic, cyclenic or cycloterpenic hydrocarbons; aldrin (ISO), chlordane (ISO), and heptachlor (ISO). This is a 6-digit subheading level code.
Why are ISO names important in HS classification for chemicals?
ISO (International Organization for Standardization) common names, such as aldrin (ISO), provide globally recognized and standardized identifiers for chemical substances. Their inclusion in HS descriptions helps ensure consistent and precise classification across international borders, reducing ambiguity and facilitating accurate customs declarations for specific chemical compounds.
Which countries are the top exporters of aldrin (HS 290382)?
In 2025, the top exporters of HS 290382 (the code used for aldrin) in UN Comtrade data were the United States ($204K, 61% of world exports), Germany ($81K) and South Africa ($17K). World exports came to about $336K, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
