Import Tips
• Include GC-MS analysis showing single peak >98% purity to qualify as 'separate chemically defined compound'
• Certify stabilizer content <1% to avoid anti-caking agent provisions that could shift classification
• Declare flash point (typically 82°C) on commercial invoice for proper hazmat fee calculation
