HS Code for Lindane

Lindane is classified under HS code 2903.81 because it is a separate chemically defined organic compound. Specifically, it is a halogenated derivative of cyclanic, cyclenic, or cycloterpenic hydrocarbons. Lindane is the gamma-isomer of 1,2,3,4,5,6-hexachlorocyclohexane (HCH). According to the Chapter 29 notes, this chapter generally includes separate chemical elements and separate chemically defined compounds. Since Lindane is a specific isomer with a defined molecular structure, it is placed here rather than in a general chemical mixture category. The classification is governed by General Interpretative Rule 1 and the specific language of subheading 2903.81, which explicitly mentions Lindane (ISO, INN). This code is used for the substance in its pure form or with added stabilizers necessary for preservation or transport, provided the additions do not render the product particularly suitable for specific use rather than for general use.

Products Included

• Pure gamma-hexachlorocyclohexane
• Lindane (ISO) technical grade
• Lindane (INN) pharmaceutical grade (unmixed)
• 1,2,3,4,5,6-Hexachlorocyclohexane (gamma-isomer)

Common Misclassification

Lindane is frequently misclassified under HS code 3808.91, which covers insecticides. While Lindane is used as an insecticide, Chapter 29 takes precedence if the product is a separate chemically defined compound. If the Lindane is formulated into a mixture or put up in forms or packings for retail sale as an insecticide, then 3808.91 would be correct. Another common error is using 2903.89 for other HCH isomers; however, 2903.81 is the specific mandatory code for the gamma-isomer (Lindane) and its HCH precursors as specified in the Harmonized System legal notes.

FAQ
