U.S. exports of ethylene-propylene-diene rubber (epdm) in primary forms (SITC 23217) totaled $57.9M in July 2026.
Importers of Ethylene-Propylene-Diene Rubber (EPDM) in Primary Forms paid $960K in duties in July 2026 — an effective duty rate of 11% on $8.4M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataEPDM's fully saturated backbone — achieved by incorporating a nonconjugated diene termonomer — gives it outstanding resistance to ozone, UV radiation, steam, and polar fluids, setting it apart from diene-based elastomers like SBR or NR. Automotive weatherstripping, roofing membranes, and wire and cable insulation are its dominant end-use segments, and the specific diene type (ENB, DCPD, or HD) along with ethylene content are key specifications that determine cure rate and compound compatibility. Certain EPDM imports have been subject to antidumping proceedings, so origin verification and mill-level documentation are important compliance steps for US buyers.

ENB (ethylidene norbornene)-based EPDM cures significantly faster than DCPD-based grades and is preferred for most automotive and industrial applications requiring high cure rates. DCPD grades are used in specific wire and cable applications. The diene type should be specified in the purchase contract and confirmed on the certificate of analysis, as substituting one for the other can cause processing and performance failures.
Yes, antidumping duty orders have been applied to EPDM from certain countries. Importers should check the current status of any applicable orders with CBP before sourcing, obtain detailed mill certificates confirming the country of origin of production, and consider requesting a scope ruling if there is any ambiguity about whether a specific grade falls within an order's scope.
