Fluorinated Ethylene Propylene Special Copolymer from United States
Fluorinated Ethylene Propylene (FEP) special copolymer pellets are a type of fluoropolymer in primary forms, produced by copolymerizing tetrafluoroethylene and hexafluoropropylene. They are classified under tariff item 3904.69.00 as 'Other' fluoropolymers because the copolymer does not meet the 95% monomer content threshold for named subheadings, and no single comonomer unit predominates sufficiently to merit a more specific classification. These pellets are used in applications requiring high chemical resistance and thermal stability, such as wire insulation and chemical processing equipment.

Import Tips
• Ensure the pellets are in primary forms (e.g
• granules or pellets) and not further worked, as this affects classification
• Provide a technical datasheet to the CBSA confirming the copolymer composition, as misclassification can lead to penalties
• Verify whether the goods qualify for preferential tariff treatment under a free trade agreement by checking the certificate of origin
