About HS Code 400239
This HS code pertains to halo-isobutene-isoprene rubber (CIIR or BIIR), also known as halogenated butyl rubber, in primary forms. This specialized synthetic rubber is a derivative of butyl rubber, offering enhanced cure versatility, improved adhesion to other rubbers, and superior gas barrier properties. It is predominantly used in tire inner liners, pharmaceutical stoppers, and high-performance seals. Global trade involves a few key chemical manufacturers supplying this material to tire companies and medical device producers. Its critical role in high-performance applications, where gas impermeability and heat resistance are paramount, ensures its steady demand in specific industrial niches, particularly in the automotive and healthcare sectors.
Products Under This Code
Chlorobutyl rubber bales, Bromobutyl rubber sheets, CIIR compounds, BIIR pellets, Halogenated butyl rubber, Tire inner liner material
Real World Examples
Arlanxeo Chlorobutyl, ExxonMobil Bromobutyl, Lanxess Bromobutyl, Tubeless tire inner liners, Pharmaceutical bottle stoppers
Common Misclassification
Frequently confused with non-halogenated butyl rubber (400231) due to similar base chemistry, but the 'halo' prefix is crucial for distinguishing its enhanced properties and applications.
Products Classified Under 4002.39
Industry
This code belongs to the Automotive & Vehicles industry.
Trade Overview
Countries with advanced tire and pharmaceutical industries, such as the USA, Germany, and Japan, are major importers and exporters.
