HS Code for Endosulfan

Endosulfan is a specific organochlorine compound classified under HS code 2920.30. This classification is found within Chapter 29, which covers organic chemicals. Heading 2920 is designated for esters of other inorganic acids of non-metals and their salts, including their halogenated, sulphonated, nitrated, or nitrosated derivatives. Endosulfan (ISO) is specifically named in the 2022 HS nomenclature update under sub-heading 2920.30 due to its status as a persistent organic pollutant (POP) and its regulation under international environmental treaties like the Stockholm Convention. The classification is based on its chemical structure as a cyclic sulfite ester. This code applies to the pure chemical or technical grade endosulfan. If the product is prepared as a finished insecticide mixed with other ingredients, the classification shifts to Chapter 38.

Products Included

Common Misclassification

Endosulfan is frequently misclassified under HS code 3808.91, which covers insecticides put up in forms or packings for retail sale or as preparations. The distinction is that 2920.30 is for the separate chemically defined compound, whereas 3808 is for formulated products (e.g., liquids or powders containing endosulfan plus surfactants or carriers). Additionally, it should not be confused with other organochlorine pesticides like Lindane or DDT, which have their own specific sub-headings in Chapter 29.
