Last updated: July 2026 dataPTFE — commercially known under trade names such as Teflon — is a fluoropolymer with exceptional chemical inertness, a broad service temperature range, and the lowest coefficient of friction of any solid polymer, properties that drive demand in semiconductor processing equipment, chemical plant linings, aerospace seals, and medical devices. The US schedule subdivides the heading into granular PTFE (3904610010) and non-granular forms such as fine powder and aqueous dispersions (3904610090), with a legacy undivided line (3904610000) also present. India leads US import supply, followed by Japan and China — a supplier mix that reflects both cost-competitive Indian production and the technical specialization of Japanese fluoropolymer producers.

Granular PTFE is a free-flowing powder produced by suspension polymerization, typically used for compression molding and ram extrusion of large billets. Non-granular forms include fine powder (produced by dispersion polymerization for paste extrusion of thin-wall tubing and wire insulation) and aqueous dispersions used for coating applications. The physical form and production method determine which 10-digit line applies, and suppliers should confirm the grade type on commercial invoices.
PTFE classified under heading 3904.61 has been subject to Section 301 tariffs when originating from China. Given that China is among the top suppliers under this heading, importers should verify the current tariff status and any available exclusions with a licensed customs broker before entry, as Section 301 lists and exclusion periods are subject to ongoing administrative review.
