About rubber; synthetic, halo-isobutene-isoprene rubber (ciir or biir), in primary forms or in plates, sheets or strip

HS code 400239 covers the classification of synthetic halo-isobutene-isoprene rubber, also known as CIIR or BIIR. This type of rubber is a specialized synthetic elastomer with unique properties that make it highly valuable in various industrial applications. As a key component in the broader rubber and plastics industry, 400239 plays an important role in supporting the manufacturing and production of a wide range of consumer and industrial goods.

Production process

The production of CIIR or BIIR rubber involves a complex chemical synthesis process. It typically begins with the copolymerization of isobutylene and isoprene monomers, followed by the halogenation of the resulting polymer to introduce the halo-isobutene-isoprene structure. This process yields a rubber material with enhanced resistance to heat, chemicals, and weathering, making it suitable for demanding applications.

Production inputs

The main inputs required for the production of HS code 400239 rubber include isobutylene and isoprene as the primary raw materials, as well as various catalysts, solvents, and other chemical additives necessary for the polymerization and halogenation processes. Additionally, specialized manufacturing equipment and machinery are essential for the efficient and precise production of this synthetic rubber.

Production outputs

The primary output of HS code 400239 is synthetic halo-isobutene-isoprene rubber, which is then further processed and incorporated into a wide range of products. This rubber is commonly used in the production of 401120 (Rubber; new pneumatic tyres, of a kind used on motor cars (including station wagons and racing cars)) and 401220 Rubber; new pneumatic tyres, of a kind used on buses or lorries, as well as various industrial gaskets, seals, and other components that require exceptional resistance to heat, chemicals, and weathering.

Revisions to 400239
