HS Code for Fluoropolymer

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.

Products Included

• Fluorinated Ethylene Propylene (FEP) in pellets
• Perfluoroalkoxy (PFA) resins
• Ethylene Tetrafluoroethylene (ETFE) in primary forms
• Polyvinylidene fluoride (PVDF)
• Polychlorotrifluoroethylene (PCTFE)

Common Misclassification

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).

FAQ

What is the HS code for fluoropolymer?

The HS code for fluoropolymers (other than PTFE) in primary forms is 3904.69.

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.
