Product classification
HS code for Fluoropolymer: 3904.69
Halogenated olefin polymers, fluoro-polymers (other than polytetrafluoroethylene), in primary forms.
Classification of fluoropolymer under HS 3904.69
Fluoropolymers, excluding polytetrafluoroethylene (PTFE), are classified under HS code 3904.69. This classification falls within Chapter 39, which governs plastics and articles thereof. Specifically, heading 3904 covers polymers of vinyl chloride or of other halogenated olefins, in primary forms. Under the Harmonized System, \"primary forms\" refers to liquids, pastes, blocks, lumps, powders, granules, and flakes. Subheading 3904.69 is a residual category for halogenated olefin polymers that do not meet the specific definition of PTFE (which is isolated under 3904.61). These materials are characterized by high resistance to solvents, acids, and bases. The classification is determined by the chemical composition of the polymer chain, specifically the presence of fluorine atoms bonded to the carbon backbone. If the product is further processed into sheets, tubes, or finished goods, it would be classified elsewhere in Chapter 39, such as 3917 or 3920, rather than under the primary form code 3904.69. The distinction between 3904.61 and 3904.69 is based on the monomeric units; 3904.69 includes copolymers like FEP, PFA, and ETFE. Customs documentation must specify the polymer type to justify the use of the \"other\" category under 3904.6.

Codes often confused with 3904.69
Common mistake. The most common misclassification occurs with HS code 3904.61, which is reserved exclusively for Polytetrafluoroethylene (PTFE). Many importers use the PTFE code for all fluoropolymers, but 3904.69 must be used for any other fluorinated olefin polymer. Another error involves classifying finished fluoropolymer tubes under 3904.69; these should actually be under 3917.39. Additionally, if the polymer is a silicone-based fluoropolymer, it may be misclassified here instead of under 3910.00 (Silicones in primary forms).
Top exporters and importers of HS 390469 (the code used for fluoropolymer), 2025
In 2025, the largest exporter of HS 390469 (the code used for fluoropolymer) in UN Comtrade data was Japan, with 20% of world exports; the largest importer in UN Comtrade data was the United States, with 16% 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 390469, not only fluoropolymer.

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 fluoropolymer
What is the HS code for Fluoropolymer?
The HS code for Fluoropolymer is 390469 (Halogenated olefin polymers; fluoro-polymers (other than polytetrafluoroethylene), in primary forms). The HS code for fluoropolymers (other than PTFE) in primary forms is 3904.69.
How do I classify Fluoropolymer for customs?
Fluoropolymer is classified under HS code 390469 — Halogenated olefin polymers; fluoro-polymers (other than polytetrafluoroethylene), in primary forms. This is a 6-digit subheading level code.
Does 3904.69 include fluoropolymer coatings?
If the coating is in a primary form (liquid or paste) and consists of the polymer without added solvents exceeding 50% by weight, it may fall here; otherwise, it may be classified as a paint or varnish in Chapter 32.
Which countries are the top exporters of fluoropolymer (HS 390469)?
In 2025, the top exporters of HS 390469 (the code used for fluoropolymer) in UN Comtrade data were Japan ($533M, 20% of world exports), the United States ($518M) and China ($450M). World exports came to about $2.7B, 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 fluoropolymer (HS 390469)?
In 2025, the top importers of HS 390469 (the code used for fluoropolymer) in UN Comtrade data were the United States ($443M, 16% of world imports), China ($378M) and Germany ($317M). World imports came to about $2.8B, 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 Fluoropolymer the same in all countries?
The base HS code 390469 for Fluoropolymer 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 fluoropolymer in Brazil?
Brazil splits HS 390469 into 2 NCM codes, so the right one for fluoropolymer depends on the product's details: 3904.69.10 (Vinylidene fluoride-hexafluoropropylene copolymer), 3904.69.90 (Other fluoro-polymers in primary forms).
