Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If predominantly alpha or beta isomers
Different HCH isomer profiles may fall under other halogenated cyclanic derivatives in same heading group.
If when containing excess petroleum solvents
High solvent content shifts to petroleum oils if solvent predominates over chemical identity.

Import Tips & Compliance
• Submit isomer composition breakdown (lindane content typically 10-15%) with import docs
• Use DOT-approved flake packaging; avoid dust generation that could trigger anti-dusting agent reclassification
• Confirm not for direct pesticide use to maintain Chapter 29 classification
