Import Tips
• Provide detailed chemical analysis (NMR, MS) confirming structure and fluorine content to verify classification under 2908.19.05.00
• Include Safety Data Sheets (SDS) and purity certificates (>98% typical) as documentation for customs clearance
• Avoid misclassification as polymer intermediates; ensure product is imported as pure compound, not pre-polymerized resin
