Vinylidene Fluoride Elastomer (VDF-based)
VDF elastomers like fluoroelastomers are synthetic rubbers from halogenated olefins, imported in primary pellet form under HTS 3904.90.1000. They exhibit elastomeric properties with vinylidene fluoride monomer at 95%+ by weight. Used in O-rings and seals for harsh chemical environments.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If after vulcanization into plates/sheets
Vulcanized fluoroelastomer plates fall under Chapter 40 finished rubber goods.
If non-elastomeric vinyl chloride copolymers
Lack of elastomeric properties shifts to non-elastomeric 'other' PVC subheadings.

Polychloroprene Latex
Polychloroprene latex is an aqueous dispersion of chloroprene rubber polymers in primary form, elastomeric under HTS 3904.90.1000 for use in adhesives and dipped goods. It qualifies as the chloroprene monomer units contribute over 95% by weight of the polymer content. Primarily imported in drums for industrial compounding.
Chloroprene Rubber (CR)
Chloroprene rubber, also known as neoprene, is an elastomeric synthetic polymer derived from chloroprene monomer, classified under HTS 3904.90.1000 as an elastomeric polymer of halogenated olefins. It is produced in primary forms such as bales or pellets for further processing into seals, gaskets, and wetsuits. The high chlorine content in its structure qualifies it as a halogenated olefin polymer meeting the 95% monomer weight requirement.
Polyvinylidene Chloride Elastomer (PVDC)
PVDC elastomer is a halogenated olefin polymer with elastomeric properties, used in primary forms for food packaging films and coatings, classified under HTS 3904.90.1000. It meets the criteria as 'other' elastomeric polymers where vinylidene chloride monomer exceeds 95% by weight. Its high chlorine content distinguishes it from standard PVC.
Chlorinated Polyethylene Elastomer (CPE)
CPE is produced by chlorination of polyethylene, creating an elastomeric polymer of halogenated olefins in primary forms like powder or pellets under HTS 3904.90.1000. Chlorine modification imparts rubber-like properties with the base olefin structure preserved. Commonly used for wire insulation and roofing membranes.
