Import Tips
• Provide detailed chemical analysis (NMR, MS) confirming aromatic structure and single oxygen function to avoid reclassification
• Include Safety Data Sheets (SDS) and CAS number (99-92-3) on commercial invoice for customs verification
• Ensure proper hazardous material labeling per DOT/IATA if shipped in quantities >1kg to prevent delays
