Mixed Halogenated Copolymer Granules
Mixed halogenated copolymer granules contain chlorine, fluorine, and bromine in a single copolymer, used for specialty coatings requiring multi-halogen properties. These granules are in primary form and classified under tariff item 3904.90.00 as 'Other' because no single halogenated monomer unit predominates sufficiently to fall under a more specific subheading.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If fluorine-containing monomers (e.g., TFE) contribute 95% or more by weight
Fluoropolymers meeting the 95% monomer content threshold are classified under 3904.61.00.
If vinyl chloride monomer units predominate by weight
Copolymers with vinyl chloride as the predominant monomer are classified under 3904.10.00 per Chapter 39 Note 4.
If the copolymer contains significant styrene units and halogenated olefins are minor
Styrene copolymers with halogenated olefins as minor components may fall under 3903.90.00 if styrene predominates.

Import Tips & Compliance
• Provide a detailed monomer composition analysis to the CBSA, showing the weight percentages of chlorine, fluorine, and bromine monomers
• If no single monomer predominates, classification under 3904.90.00 is appropriate, but if one halogenated monomer exceeds 95%, a more specific subheading may apply
• Ensure the granules are not further worked beyond primary form, as this could reclassify the product

Brominated Polyethylene Copolymer
Brominated polyethylene copolymer is a halogenated olefin polymer in primary pellets, used for flame-retardant compounds. The bromine addition modifies the polyethylene, creating a polymer of a halogenated olefin. This product falls under tariff item 3904.90.00 as an 'Other' polymer of halogenated olefins in primary forms.
Chlorinated Polyethylene Elastomer (CPE)
Chlorinated polyethylene (CPE) is produced by chlorinating polyethylene, resulting in a rubbery polymer of halogenated olefins. It is imported in primary forms such as powder or pellets and is used in wire insulation, hoses, and impact modifiers. This product falls under tariff item 3904.90.00 as an 'Other' polymer of halogenated olefins in primary forms.
Chlorinated Polyethylene Granules CPE
Chlorinated polyethylene (CPE) granules are produced by chlorinating polyethylene, resulting in a rubbery halogenated olefin polymer used in wire insulation and hoses. The product is in primary form (granules) and falls under tariff item 3904.90.00 as an 'Other' polymer of halogenated olefins in primary forms.
Chloroprene Rubber (CR)
Chloroprene rubber (neoprene) is an elastomeric synthetic polymer derived from chloroprene monomer, a halogenated olefin. It is imported in primary forms such as solid chunks or pellets and is used in gaskets, hoses, and adhesives. This product falls under tariff item 3904.90.00 as an 'Other' polymer of halogenated olefins in primary forms.
Chlorotrifluoroethylene Copolymer Pellets
Chlorotrifluoroethylene (ECTFE) copolymer pellets are made from chlorotrifluoroethylene and ethylene, offering corrosion resistance for pipes. The chlorotrifluoroethylene monomer units predominate by weight, classifying it as a polymer of a halogenated olefin. This product falls under tariff item 3904.90.00 as an 'Other' polymer of halogenated olefins in primary forms.
Fluorochlorinated Polyolefin Pellets
Fluorochlorinated polyolefin pellets blend fluoro and chloro olefin monomers into a polymer used primarily for wire and cable coatings. These pellets are in primary form, as defined by Chapter 39 Note 6, and are classified under tariff item 3904.90.00 as 'Other' polymers of halogenated olefins, since they do not meet the specific subheading criteria for single-halogen polymers.
