Product classification
HS code for EPDM rubber: 4002.70
Rubber, synthetic, ethylene-propylene-non-conjugated diene rubber (EPDM), in primary forms or in plates, sheets or strip.
Classification of EPDM rubber under HS 4002.70
EPDM (Ethylene-Propylene-Non-Conjugated Diene Rubber) is classified under HS code 4002.70. This classification falls under Chapter 40, which covers rubber and articles thereof. Heading 4002 is specifically for synthetic rubber and factice derived from oils, in primary forms or in plates, sheets, or strip. EPDM is a type of synthetic elastomer characterized by its excellent resistance to heat, ozone, and weather. To fall under 4002.70, the material must be in a 'primary form' (such as liquids, pastes, blocks, lumps, or powders) or in unvulcanized plates, sheets, or strips. The classification is determined by the chemical composition of the polymer, which must consist of ethylene and propylene with a small amount of a non-conjugated diene to allow for vulcanization. This code is critical for manufacturers in the automotive and construction industries who import raw EPDM for further processing into seals, hoses, and roofing membranes.

Codes often confused with 4002.70
Common mistake. A common misclassification occurs when EPDM is already vulcanized. If the EPDM is in the form of vulcanized plates, sheets, or strips, it should be classified under 4008. If it is a finished article like a gasket or a hose, it falls under 4016 or 4009 respectively. Another error is using 4002.19, which is for SBR (Styrene-Butadiene Rubber). While both are synthetic rubbers, the chemical monomers are different. Additionally, EPDM should not be confused with EPM (Ethylene-Propylene Rubber without the diene), though EPM is often grouped nearby in trade statistics, the specific 4002.70 code requires the diene component.
Top exporters and importers of HS 400270 (the code used for EPDM rubber), 2025
In 2025, the largest exporter of HS 400270 (the code used for EPDM rubber) in UN Comtrade data was the United States, with 29% of world exports; the largest importer in UN Comtrade data was China, with 18% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about EPDM rubber
What is the HS code for EPDM rubber?
The HS code for EPDM rubber is 400270 (Rubber; synthetic, ethylene-propylene-non-conjugated diene rubber (EPDM), in primary forms or in plates, sheets or strip). The HS code for EPDM rubber in primary forms or unvulcanized sheets is 4002.70.
How do I classify EPDM rubber for customs?
EPDM rubber is classified under HS code 400270 — Rubber; synthetic, ethylene-propylene-non-conjugated diene rubber (EPDM), in primary forms or in plates, sheets or strip. This is a 6-digit subheading level code.
What if the EPDM rubber is already shaped into a finished seal?
If the EPDM is a finished, vulcanized product like a seal or gasket, it is no longer classified under 4002.70 and should instead be classified under 4016.93.
Which countries are the top exporters of EPDM rubber (HS 400270)?
In 2025, the top exporters of HS 400270 (the code used for EPDM rubber) in UN Comtrade data were the United States ($572M, 29% of world exports), South Korea ($482M) and Saudi Arabia ($307M). World exports came to about $2.0B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
