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.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If vinyl acetate comonomer >=5% and specifically named
Named copolymers like ethylene-vinyl acetate with qualifying content fall under 3901.30 per note (a)(2), if not elastomeric.
If vinyl chloride predominates
Predominant monomer determines heading under note (a)(4) when ethylene does not lead.
If chemically modified or latex form
Processed beyond primary form into synthetic latex rubber moves to Chapter 40.

Import Tips & Compliance
• Request detailed copolymer analysis reports to prove ethylene predominance per subheading note (a)(4)
• Avoid importing masterbatched versions, which may classify under 3901.90.90
• Watch for contamination claims at customs affecting primary form status
