Ethylene Propylene Diene Monomer (EPDM) Rubber from Mexico
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.

Import Tips
• Verify monomer composition via supplier certificates to confirm >95% ethylene/propylene content for elastomeric classification
• Ensure primary form (pellets/granules) not compounded products to avoid reclassification
• Common pitfall: mislabeling as general ethylene polymers under 3901.10
