Subheadings
Products classified under Tariff item 4002.20.00
BR Oil-Extended Rubber Bale
Bales of butadiene rubber (BR) extended with mineral oil, a permitted extender under Chapter 40 Note 5(A)(iii). The oil extension improves processing while the product retains its essential character as raw synthetic rubber in primary form.
Butadiene Rubber Powder
Butadiene rubber (BR) in fine powder form, a primary form under Chapter 40 Note 3(b) as 'powders, granules, crumbs and similar bulk forms.' The powder is uncompounded and retains the essential character of raw synthetic rubber for use in rubber compounding and asphalt modification.
Cis-1,4-Polybutadiene Rubber Latex
Prevulcanized latex of cis-1,4-polybutadiene rubber, a liquid dispersion in primary form under Chapter 40 Note 3(a). The prevulcanization is permitted per Note 5(A)(i) as it is added for the preparation of pre-vulcanised rubber latex, and the product retains its essential character as raw synthetic rubber.
High Cis-Polybutadiene Rubber Bale
Baled high-cis polybutadiene rubber, an uncompounded synthetic rubber in primary bulk form. The high-cis microstructure provides excellent elasticity and abrasion resistance, making it suitable for conveyor belts and footwear soles. It meets the vulcanization and recovery tests of Chapter 40 Note 4 without prohibited additives.
Lithium-Catalyzed Butadiene Rubber Crumb
Crumb form of solution butadiene rubber produced via lithium catalysis, a primary form under Chapter 40 Note 3(b). The crumbs are uncompounded and retain the essential character of raw synthetic rubber for use in wire insulation compounds.
Neodymium-Catalyzed Polybutadiene Rubber
Baled neodymium-catalyzed polybutadiene rubber with high microstructure, an uncompounded synthetic rubber in primary form. The neodymium catalyst produces a rubber with excellent dynamic properties for golf balls and tires. It meets the requirements of Chapter 40 Note 4 without prohibited additives.
Polybutadiene Rubber (BR) Granules
Granular form of cis-1,4-polybutadiene rubber, a primary form under Chapter 40 Note 3(b) as 'granules.' The granules are uncompounded and retain the essential character of raw synthetic rubber for tire manufacturing and synthetic golf balls.
Solution Styrene Butadiene Rubber (SSBR)
Solution-polymerized styrene-butadiene rubber (SSBR) in crumb form, a synthetic rubber that is predominantly butadiene with a minor styrene content. The crumbs are uncompounded and retain the essential character of raw butadiene rubber for high-performance tires. It meets the vulcanization and recovery tests of Chapter 40 Note 4.
Styrene-Butadiene Rubber (SBR) Latex
Liquid dispersion of butadiene rubber copolymerized with styrene, used in adhesives and carpet backings. The product is predominantly butadiene rubber in primary latex form, meeting the vulcanization and recovery tests of Chapter 40 Note 4. It is uncompounded and retains the essential character of raw synthetic rubber.
Synthetic Isoprene-Butadiene Rubber (SIBR)
Granular form of isoprene-butadiene rubber (SIBR), a copolymer where butadiene is the predominant monomer. The granules are uncompounded and retain the essential character of raw butadiene rubber for tire treads. It meets the vulcanization and recovery tests of Chapter 40 Note 4.
