Import Tips
• Include supplier's synthesis pathway documentation to verify naphthalene substitution pattern matches tariff description
• Label with GHS pictograms (corrosive) and batch-specific CAS if assigned; critical for CBP examination
• Avoid bulk packaging >25kg/drum without stabilizer, as chapter notes require stabilizers only for preservation
