Import Tips
• Label as 'for research use only' to avoid pesticide registration requirements; mislabeling causes CBP holds
• Verify no solvents present per chapter note (e); solvated forms may classify under 2942 for organic compounds in solution
• Maintain chain-of-custody documentation to prevent dual-use concerns under Chemical Weapons Convention
