HS v2022 Code: 400270

About rubber; synthetic, ethylene-propylene-non-conjugated diene rubber (epdm), in primary forms or in plates, sheets or strip

HS code 400270 covers the classification of synthetic ethylene-propylene-non-conjugated diene rubber (EPDM), a versatile and widely-used type of rubber. EPDM is a key material in the manufacturing of a diverse range of products, from automotive parts to construction materials, making it an important component in many industries. As a synthetic rubber, EPDM offers advantages over natural rubber in terms of durability, weather resistance, and chemical stability, contributing to its growing global demand.

Production process

The production of EPDM involves a multi-step polymerization process. Ethylene, propylene, and a non-conjugated diene monomer are combined and polymerized under high heat and pressure, typically using a Ziegler-Natta or metallocene catalyst. The resulting EPDM polymer is then processed into various primary forms, such as sheets, plates, or granules, ready for further fabrication and use in downstream applications.

Production inputs

The primary inputs for the EPDM industry include ethylene, propylene, and non-conjugated diene monomers, such as ethylidene norbornene (ENB) or dicyclopentadiene (DCPD). Additionally, the industry relies on specialized catalysts, processing equipment, and energy sources to facilitate the polymerization and shaping of the EPDM material. 271011 Petroleum oils and oils obtained from bituminous minerals, crude and 271012 Petroleum oils and oils obtained from bituminous minerals, other than crude are also important inputs, as they provide the feedstock for the production of the key monomers.

Production outputs

The EPDM produced under HS code 400270 is primarily used in the manufacture of a wide range of products, including automotive parts (e.g., seals, gaskets, hoses), construction materials (e.g., roofing membranes, weatherstripping), and various industrial goods (e.g., electrical insulation, conveyor belts). The output of this industry may be further processed and consumed by industries covered under other HS codes, such as 401699 Articles of vulcanized rubber n.e.c., other than hard rubber and 401110 (New pneumatic tyres, of rubber - of a kind used on motor cars (including station wagons and racing cars)).
