Import Tips & Compliance
• Include flash point data (23°C) in SDS for DOT classification; common error is shipping as non-hazmat
• Verify no halogenated impurities via HPLC to stay within Chapter 29 pure compounds scope
• For pharma intermediates, provide end-use statement to avoid dual-use chemical scrutiny
