Import Tips
• Provide detailed chemical analysis and CAS number (63718-21-0) documentation to confirm aromatic classification under Chapter 29
• Ensure purity certificates as impurities may affect classification if exceeding chapter note thresholds
• Label containers with UN numbers if hazardous; common pitfall is misclassifying as Chapter 32 dye intermediate
