6. What logistics options and costs should I consider when importing Teflon sheets from overseas suppliers?

Evaluate multiple freight options—sea freight for large volumes offers cost efficiency, while air freight provides faster delivery for urgent needs. Consider FOB (Free On Board), CIF (Cost, Insurance, Freight), or DDP (Delivered Duty Paid) terms based on your logistics capabilities and cost preferences. Account for customs duties, taxes, and import regulations specific to your country, such as Brazil, Turkey, or Nigeria. Collaborate with experienced freight forwarders familiar with the import process for fluoropolymer materials. Proper planning and supplier logistics coordination reduce delays, minimize costs, and ensure smooth delivery.
