HS v2017 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 a diverse range of industries, from automotive manufacturing to construction, making it an important component of the broader 400000 Rubber and articles thereof sector. Its unique properties, such as resistance to weathering, ozone, and chemicals, make it a valuable material for numerous applications across the global economy.

Production process

The production of EPDM rubber typically involves the copolymerization of ethylene, propylene, and a non-conjugated diene monomer, such as ethylidene norbornene (ENB) or dicyclopentadiene (DCPD). This process is carried out under controlled temperature and pressure conditions, often using a Ziegler-Natta or metallocene catalyst system. 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 industries.

Production inputs

The main inputs required for the production of EPDM rubber include the raw materials of ethylene, propylene, and a non-conjugated diene monomer. Additionally, the manufacturing process requires specialized equipment, such as polymerization reactors, extruders, and compounding machinery. Other key inputs may include catalysts, stabilizers, and various additives to enhance the rubber's properties and performance characteristics.

Production outputs

The primary output of HS code 400270 is EPDM rubber in various forms, including sheets, plates, and strips. This material is then consumed by a wide range of industries, such as 401110 New pneumatic tyres, of rubber for the automotive sector, 401700 Articles of vulcanized rubber n.e.c. for construction and industrial applications, and 392010 Plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials for the plastics industry.

Revisions to 400270
