This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the powder is formulated with other ingredients for direct use as a pesticide
Formulated pesticides are classified in heading 38.08, not as pure chemical compounds.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Provide a technical data sheet confirming the gamma-HCH content and absence of other isomers that could affect classification
• Verify if the product is subject to the Stockholm Convention on Persistent Organic Pollutants, as Canada restricts certain HCH uses
• Ensure proper labeling for hazardous material transport

Gamma-HCH Pharmaceutical Grade
Pharmaceutical-grade gamma-hexachlorocyclohexane (lindane) meeting USP standards, used as an active ingredient in scabicide synthesis. This is a pure, chemically defined isomer of 1,2,3,4,5,6-hexachlorocyclohexane, falling under tariff item 2903.81.00 as a halogenated derivative of a cyclanic hydrocarbon.
HCH Lindane Aqueous Solution 20%
A 20% aqueous solution of lindane (gamma-HCH) in water, used for safer handling in chemical synthesis. Per Chapter Note 1(d), products of this chapter dissolved in water are classifiable under the same heading, so this solution falls under tariff item 2903.81.00.
HCH Mixed Isomers Flake Form
Technical flakes of 1,2,3,4,5,6-hexachlorocyclohexane (HCH) containing mixed isomers including lindane, used for lindane extraction. This product is specifically named in tariff item 2903.81.00, covering HCH regardless of isomer composition, as it is a halogenated cyclanic hydrocarbon.
Lindane 99% Pure Crystals
High-purity lindane crystals (99% gamma-HCH) used in pharmaceutical and agricultural chemical synthesis. As a pure, chemically defined isomer of 1,2,3,4,5,6-hexachlorocyclohexane, it is classified under tariff item 2903.81.00, which specifically includes lindane.
Lindane Stabilized for Transport
Lindane powder with added stabilizers necessary for preservation or transport, maintaining its identity as a chemically defined HCH compound. Per Chapter Note 1(f), stabilizers added for preservation or transport do not affect classification, so this falls under tariff item 2903.81.00.
Purified Lindane Distillation Residue
Purified lindane distillation residue containing over 60% gamma-HCH isomers, used for secondary recovery or lower-grade synthesis. Despite being a residue, it retains its primary identity as 1,2,3,4,5,6-hexachlorocyclohexane, so it falls under tariff item 2903.81.00.
