HS code for Ethylene-propylene-diene rubber: 4002.70
Rubber, synthetic, ethylene-propylene-non-conjugated diene rubber (EPDM), in primary forms or in plates, sheets or strip.
Classification of ethylene-propylene-diene rubber under HS 4002.70
Ethylene-propylene-diene rubber, commonly known as EPDM, is classified under HS code 4002.70. This classification is determined by the material's chemical composition and its state as a synthetic rubber. According to Note 4 to Chapter 40 of the Harmonized System, synthetic rubber applies to unsaturated synthetic substances which can be irreversibly transformed by vulcanization with sulphur into non-thermoplastic substances. EPDM is a terpolymer of ethylene, propylene, and a non-conjugated diene, which allows for vulcanization via the residual unsaturation in the side chains. The classification 4002.70 specifically covers this rubber when it is in primary forms, such as blocks, crumbs, or granules, or in plates, sheets, and strips. The determination depends on the product not being compounded with fillers, plasticizers, or other substances that would move it to heading 40.05. The durability, heat resistance, and weathering properties of EPDM make it a distinct category within the synthetic rubber family, necessitating its own specific subheading under the 4002 group.

Codes often confused with 4002.70
Common mistake. EPDM is frequently misclassified under HS code 4005.10 or 4005.91. These codes refer to compounded rubber, which is rubber that has been mixed with carbon black, silica, or other reinforcing agents. If the EPDM has already been mixed with these additives, it must be moved from 4002 to 4005. Additionally, finished EPDM products like gaskets or seals are classified under 4016.93, not the raw material code 4002.70. Importers often confuse these based on the material name rather than the stage of processing.
Top exporters and importers of HS 400270 (the code used for ethylene-propylene-diene rubber), 2025
In 2025, the largest exporter of HS 400270 (the code used for ethylene-propylene-diene 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.
Figures cover everything classified under HS 400270, not only ethylene-propylene-diene rubber.

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).
