Import Tips & Compliance
• Include GC-MS analysis confirming >98% purity to prevent classification as cosmetic preparation under 3304
• Declare flash point and VOC content; common pitfall is incorrect hazardous material documentation
• For bulk imports, provide manufacturing process flow to demonstrate not a formulated mixture
