Import Tips & Compliance
• Provide detailed chemical structure and CAS number (90-64-2) to confirm aromatic alcohol function classification
• For cosmetic-grade imports, separate bulk chemical from finished products to avoid Chapter 33 duties
• Watch for contamination; impure lots may be reclassified under general 2918.19 provisions
