Overview
This HTS classification covers ethylene-propylene-nonconjugated diene rubber (EPDM) in its primary forms or in plates, sheets, or strip. EPDM is a synthetic rubber known for its excellent resistance to heat, weathering, ozone, and chemicals, making it suitable for a wide range of industrial and automotive applications. It is characterized by the presence of ethylene and propylene monomers, along with a nonconjugated diene monomer that allows for vulcanization.
EPDM is distinguished from its sibling categories by its specific monomer composition. Unlike styrene-butadiene rubber (SBR), butadiene rubber (BR), isobutene-isoprene (butyl) rubber (IIR), chloroprene (chlorobutadiene) rubber (CR), or acrylonitrile-butadiene rubber (NBR), EPDM's unique combination of monomers imparts its distinctive properties, particularly its superior resistance to environmental degradation and high temperatures.
As this is a leaf node in the HTS classification, there are no further subdivisions. Classification of EPDM under 4002.70.00.00 is definitive for the material meeting the specified chemical composition and physical form. Customs officers will rely on product specifications, chemical analyses, and physical inspection to confirm that the rubber is indeed ethylene-propylene-nonconjugated diene rubber.
