Import Tips
• Comply with IATA/49 CFR packing instructions for Division 2.3 poison gases; include cryogenic handling certifications
• Declare exact purity (>99%) to avoid reclassification; pitfall is failing to specify physical state on commercial invoice
• Insure against spontaneous combustion risks; use facilities with fluorine-compatible piping
