Import Tips & Compliance
• Ensure the TFE/CTFE pellets are in primary forms and that the monomer composition is clearly documented
• Provide the ratio of tetrafluoroethylene to chlorotrifluoroethylene for classification
• Be aware that if tetrafluoroethylene predominates, the product may fall under subheading 3904.61
