Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If linear low-density polyethylene without elastomeric properties
Non-elastomeric ethylene-alpha olefin copolymers classify as polyethylene, not elastomers.
If octene or other alpha-olefin predominates
Subheading note (a)(4) prioritizes the weight-predominant monomer unit.
If containing plasticizers and imported as plates/sheets
Finished non-primary forms with plasticizers fall under plates, sheets in 3920 per subheading note.

Import Tips & Compliance
• Provide technical data sheets confirming elastomeric nature and monomer ratios to CBP
• Ensure packaging labels 'primary form' to prevent misclassification as articles
• Pitfall: blending with other polymers may trigger 'other' subheading 3901.90.90

Ethylene Propylene Diene Monomer (EPDM) Rubber
EPDM is an elastomeric copolymer of ethylene, propylene, and a diene, with ethylene and propylene monomers contributing over 95% by weight, classified under 3901.90.10 as an elastomeric polymer of ethylene in primary form. It is supplied as pellets or granules for use in manufacturing weather-resistant seals and gaskets. This classification follows subheading note (a)(2) for named copolymers.
Ethylene-Vinyl Acetate (EVA) Elastomer Pellets
EVA elastomer is a copolymer where ethylene units predominate over vinyl acetate, exceeding 95% ethylene content by weight, making it an elastomeric polymer under HTS 3901.90.10. It is imported in primary pellet form for flexible foam production in footwear. Subheading rules classify it here due to predominant ethylene monomer.
