Products classified under Tariff item 4002.20
BR Oil-Extended Rubber Bale
Butadiene rubber (BR) extended with mineral oil, presented in bale form. The mineral oil extender is permitted under Chapter 40 Note 5(A)(iii), and the product retains its essential character as a raw synthetic rubber in primary form.
4002.20.00Butadiene Rubber Powder
Butadiene rubber in fine powder form, used for rubber compounding and asphalt modification. Powder is a primary form under Chapter 40 Note 3(b), and the product is uncompounded, retaining its raw material character.
4002.20.00Cis-1,4-Polybutadiene Rubber Latex
Prevulcanized latex of cis-butadiene rubber for dipping and coating applications. The latex is a primary liquid form under Chapter 40 Note 3(a), and prevulcanization is permitted per Note 5(A)(i).
4002.20.00High Cis-Polybutadiene Rubber Bale
High-cis polybutadiene rubber in bale form, unvulcanized and uncompounded, for conveyor belts and footwear soles. The bale is a primary bulk form under Chapter 40 Note 3(b), and the product passes the elongation and recovery tests.
4002.20.00Lithium-Catalyzed Butadiene Rubber Crumb
Solution butadiene rubber crumbs produced via lithium catalysis, for wire insulation compounds. The crumb form is a primary bulk form under Chapter 40 Note 3(b), and the rubber is uncompounded.
