HS Code for EPDM rubber

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.

Products Included

• EPDM rubber in bales or crumbs
• Unvulcanized EPDM sheets for industrial use
• EPDM liquid dispersions or pastes
• Ethylene-propylene-diene monomer masterbatch (unvulcanized)
• EPDM granules used for synthetic track surfacing (in primary form)

Common Misclassification

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.

FAQ

What is the HS code for EPDM rubber?

The HS code for EPDM rubber in primary forms or unvulcanized sheets is 4002.70.

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.
