Vinylidene Fluoride Hexafluoropropylene Copolymer
This copolymer (e.g., PVDF-HFP) combines vinylidene fluoride and hexafluoropropylene for flexible membranes in batteries. HTS 3904.90.5000 covers it as 'Other' halogenated olefin polymer in primary form, as comonomers don't meet 95% named copolymer criteria.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other fluoroelastomer copolymers named specifically
Series subheadings prioritize if 95% comonomer match; else predominant monomer rules.
If chemically modified without specific cover
Note (a)(3) sends unmodified-equivalent mods to 'Other' in acrylic series if applicable.
If imported as battery component set
Assembled articles with polymers shift from primary forms to end-use Chapter 85.

Import Tips & Compliance
• Document exact comonomer ratios (<95% for each) via GPC/FTIR to justify 'Other' per subheading note (a)(2)
• Certify non-household use to avoid 3924 misclassification; include end-use declarations
Related Products under HTS 3904.90.50.00
Polyvinylidene Chloride Resin PVDC
Polyvinylidene chloride (PVDC) resin is a halogenated olefin polymer used primarily for food packaging films due to its excellent barrier properties against oxygen and moisture. It falls under HTS 3904.90.5000 as a primary form polymer of a halogenated olefin (vinylidene chloride), classified in 'Other' since it does not meet the 95% monomer threshold for specific copolymers in earlier subheadings.
Chlorinated Polyethylene Granules CPE
Chlorinated polyethylene (CPE) is produced by chlorinating polyethylene, resulting in a rubbery halogenated olefin polymer used in wire insulation and hoses. Classified under HTS 3904.90.5000 as 'Other' polymers of halogenated olefins in primary forms (granules), as the chlorinated structure derives from olefin base but doesn't fit specific prefixes.
Chlorotrifluoroethylene Copolymer Pellets
ECTFE copolymer pellets from chlorotrifluoroethylene and ethylene offer corrosion resistance for pipes. Classified in HTS 3904.90.5000 as other primary polymers of halogenated olefins, with ethylene comonomer <95% preventing specific subheading.
Brominated Polyethylene Copolymer
Brominated polyethylene copolymer in primary pellets for flame-retardant compounds. HTS 3904.90.5000 as 'Other' halogenated (bromine) olefin polymer, based on ethylene with Br addition.
Mixed Halogenated Copolymer Granules
Granules of copolymer with Cl/F/Br halogens for specialty coatings. 3904.90.5000 'Other' due to multi-halogen not specific.
Fluorochlorinated Polyolefin Pellets
Pellets blending fluoro and chloro olefins for wire coatings. Primary form under 3904.90.5000.
