HS Code for Teflon resin

Teflon resin, technically known as polytetrafluoroethylene (PTFE), is classified under HS code 3904.61. This classification is determined by the General Rules of Interpretation (GRI) 1 and 6, as well as the specific notes for Chapter 39, which covers plastics and articles thereof. Within this chapter, heading 3904 applies to polymers of vinyl chloride or of other halogenated olefins, in primary forms. Since PTFE is a fluoropolymer consisting of carbon and fluorine, it falls under the halogenated olefin category. Subheading 3904.61 is specifically reserved for polytetrafluoroethylene. To qualify for this code, the material must be in a \"primary form,\" which according to Chapter 39 Note 6, includes liquids, pastes, dispersions, blocks of irregular shape, lumps, powders, granules, and similar bulk forms. The resin is valued for its high resistance to heat and chemicals, and its classification remains consistent regardless of whether it is intended for industrial coatings, gasket manufacturing, or non-stick cookware applications, provided it has not been further worked into a finished article.

Products Included

• PTFE granular resin used for molding and extrusion
• Polytetrafluoroethylene fine powder for paste extrusion
• Aqueous dispersions of PTFE used for coating glass cloth
• Micronized PTFE powders used as additives in inks or lubricants
• Unfilled PTFE resins in pelletized or powder form

Common Misclassification

Teflon resin is frequently confused with other fluoropolymers classified under HS code 3904.69, which covers \"other\" fluoropolymers such as FEP (Fluorinated Ethylene Propylene) or PFA (Perfluoroalkoxy). While these are chemically similar, 3904.61 is strictly for PTFE. Another common error involves classifying semi-finished products, such as PTFE rods, sheets, or tubes, under this code; these should be classified under 3916, 3920, or 3917 respectively, as they are no longer in primary forms. Additionally, finished gaskets made of Teflon are classified under 3926.90 or 8484.10 depending on their construction.
