Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing heterocyclic ring impurities
Presence of unintended heterocyclic structures from synthesis shifts to Chapter 29 heterocyclic compounds heading.
If for laboratory reagent mixtures
Chemical preparations in lab packs for analysis fall under prepared binders or Chapter 38 mixtures.

Import Tips & Compliance
• Provide GC-MS analysis confirming gamma isomer purity >99% to match HTS description exactly
• Declare as 'pure chemical for synthesis' to avoid pesticide classification; watch for anti-dusting agent additions
• Comply with TSCA import certification; common issue is improper UN packaging for hazardous goods

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.
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
