Import Tips
• Classify under UN 3467 for fluorinated phosphorus compounds and ensure IMCO labeling on all shipping containers
• Provide certificates of analysis confirming single alkyl group structure to match statistical suffix requirements
• Check for CWC (Chemical Weapons Convention) restrictions as some phosphonyl halides have dual-use concerns
