HS code for Teflon resin: 3904.61

Halogenated olefin polymers, fluoro-polymers, polytetrafluoroethylene, in primary forms.

Classification of teflon resin under HS 3904.61

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.

Codes often confused with 3904.61

Common mistake. 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.

Top exporters and importers of HS 390461 (the code used for teflon resin), 2025

In 2025, the largest exporter of HS 390461 (the code used for teflon resin) in UN Comtrade data was China, with 24% of world exports; the largest importer in UN Comtrade data was Germany, with 13% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about teflon resin

What is the HS code for Teflon resin?

The HS code for Teflon resin is 390461 (Halogenated olefin polymers; fluoro-polymers, polytetrafluoroethylene, in primary forms). The HS code for Teflon resin (polytetrafluoroethylene) in primary forms such as powder or granules is 3904.61.

How do I classify Teflon resin for customs?

Teflon resin is classified under HS code 390461 — Halogenated olefin polymers; fluoro-polymers, polytetrafluoroethylene, in primary forms. This is a 6-digit subheading level code.

Does this code include Teflon tape?

No, Teflon thread seal tape is a finished article and is typically classified under HS code 3920.99, which covers other plates, sheets, film, foil, and strip of plastics.

Which countries are the top exporters of teflon resin (HS 390461)?

In 2025, the top exporters of HS 390461 (the code used for teflon resin) in UN Comtrade data were China ($272M, 24% of world exports), the United States ($141M) and India ($138M). World exports came to about $1.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
