Product classification
HS code for PTFE resin: 3904.61
Halogenated olefin polymers, fluoro-polymers, polytetrafluoroethylene, in primary forms.
Classification of PTFE resin under HS 3904.61
Polytetrafluoroethylene (PTFE) resin is classified under HS code 3904.61. This classification is found in Chapter 39, which covers plastics. Heading 3904 specifically includes polymers of vinyl chloride or of other halogenated olefins in primary forms. Since PTFE is a polymer of tetrafluoroethylene (a halogenated olefin), it is logically grouped here. Subheading 3904.61 is the specific international code for PTFE. This material is known for its high thermal stability, chemical resistance, and low coefficient of friction. In its primary form, PTFE can exist as a fine powder, a granular resin, or an aqueous dispersion. The classification is determined by the chemical identity of the monomer units. According to Chapter 39 Note 4, copolymers are classified in the subheading covering the units which predominate by weight. For PTFE, the tetrafluoroethylene units must be the majority. This classification follows GRI 1, which relies on the heading text, and GRI 6, which governs subheading level classification.

Codes often confused with 3904.61
Common mistake. PTFE resin is often confused with 3904.69, which is the category for 'other' fluoropolymers like FEP or PFA. It is also frequently misclassified when it has been processed into semi-finished forms; for example, PTFE tape is classified under 3920.99 or 3919.10, and PTFE tubing falls under 3917.29. Importers must ensure the product is truly in a 'primary form' (powder, granule, or liquid) to use 3904.61. If the PTFE is mixed with other materials as a lubricant, it might be classified in Chapter 27 or 34 depending on the petroleum content.
Top exporters and importers of HS 390461 (the code used for PTFE resin), 2025
In 2025, the largest exporter of HS 390461 (the code used for PTFE 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.
Figures cover everything classified under HS 390461, not only PTFE resin.

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 PTFE resin
What is the HS code for PTFE resin?
The HS code for PTFE resin is 390461 (Halogenated olefin polymers; fluoro-polymers, polytetrafluoroethylene, in primary forms). The HS code for PTFE in primary forms, such as powders or granules, is 3904.61.
How do I classify PTFE resin for customs?
PTFE resin is classified under HS code 390461 — Halogenated olefin polymers; fluoro-polymers, polytetrafluoroethylene, in primary forms. This is a 6-digit subheading level code.
Are PTFE dispersions classified under the same code?
Yes, aqueous dispersions of PTFE are considered a primary form under Chapter 39 Note 6 and are classified under HS code 3904.61.
Which countries are the top exporters of PTFE resin (HS 390461)?
In 2025, the top exporters of HS 390461 (the code used for PTFE 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.
Which countries are the top importers of PTFE resin (HS 390461)?

World imports 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.
Is the HS code for PTFE resin the same in all countries?
The base HS code 390461 for PTFE resin is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for PTFE resin in Brazil?
Brazil splits HS 390461 into 2 NCM codes, so the right one for PTFE resin depends on the product's details: 3904.61.10 (PTFE liquids, pastes and dispersions), 3904.61.90 (PTFE powders, granules and other forms).
