Import Tips
• Include cure system details (peroxide vs bisphenol) in documentation as it affects processing but not HTS
• Prevent undervaluation claims by declaring Mooney viscosity and specific gravity accurately
• Bulk shipments common; ensure container ventilation per fluoropolymer handling guidelines
