Import Tips
• Provide GC-MS analysis confirming <10 ppm moisture and C4 impurities to maintain pure compound status
• Use refrigerated tankers maintaining -4°C to prevent polymerization during ocean transit
• Declare as UN1010; obtain advance CBP approval for bulk chemical imports exceeding 1000 kg
