Products classified under HTS 2903.81.00.00
Lindane Technical Grade Powder
Lindane, chemically 1,2,3,4,5,6-hexachlorocyclohexane (gamma isomer), is a technical grade powder used primarily as an intermediate in pesticide manufacturing. It falls under HTS 2903.81.00.00 as a halogenated derivative of cyclanic hydrocarbons, specifically the defined compound HCH including lindane. This pure chemical form meets chapter 29 requirements for separate chemically defined organic compounds.
Lindane 99% Pure Crystals
High-purity lindane crystals (99% gamma-HCH) used in pharmaceutical and agricultural chemical synthesis. Classified under HTS 2903.81.00.00 as it is the pure, chemically defined 1,2,3,4,5,6-hexachlorocyclohexane isomer. Meets chapter criteria for separate halogenated organic compounds without excluded additives.
HCH Mixed Isomers Flake Form
1,2,3,4,5,6-Hexachlorocyclohexane (HCH) technical flakes containing mixed isomers including lindane, used for lindane extraction. Falls squarely under HTS 2903.81.00.00 as the specific named halogenated cyclanic hydrocarbon. Chapter notes confirm applicability to chemically defined compounds regardless of isomer mixture.
Lindane Stabilized for Transport
Lindane powder with added stabilizer for safe transport, remaining a chemically defined HCH compound. HTS 2903.81.00.00 applies per chapter note (f) allowing stabilizers necessary for preservation/transport without changing classification. Used in industrial pesticide synthesis.
Technical Lindane 90% Wettable Powder
90% lindane wettable powder base for further formulation, technically still HCH with minimal dispersants. HTS 2903.81.00.00 covers as chemically defined compound per chapter note (g) allowing identification aids. Primarily for pesticide industry processing.
HCH Lindane Aqueous Solution 20%
20% lindane dissolved in water for safe handling in synthesis operations. Qualifies under HTS 2903.81.00.00 per chapter note (d) for products of this heading dissolved in water. Remains chemically defined HCH without excluded characteristics.
Purified Lindane Distillation Residue
Residue from lindane purification containing >60% gamma-HCH isomers. Still classified as HTS 2903.81.00.00 as primary HCH chemical identity maintained. Used for secondary recovery or lower-grade synthesis.
Gamma-HCH Pharmaceutical Grade
Pharmaceutical-grade gamma-hexachlorocyclohexane (lindane) meeting USP standards for scabicide synthesis. Classified in HTS 2903.81.00.00 as pure HCH isomer, a halogenated cyclanic hydrocarbon. Excluded from Chapter 30 as it's a bulk chemical, not formulated dosage form.
