Products classified under HTS 4002.60.00.00
Synthetic Isoprene Rubber Latex
A liquid dispersion of isoprene rubber (IR) used in the production of adhesives, coatings, and dipped goods like gloves. Classified under HTS 4002.60.00.00 as synthetic rubber in primary form (latex), meeting the vulcanization and elasticity criteria of chapter note 2 without prohibited compounding agents.
Isoprene Rubber (IR) Granules
Granular form of synthetic isoprene rubber supplied for easy handling in tire and rubber goods manufacturing. Falls under HTS 4002.60.00.00 as synthetic rubber in primary bulk form (granules), retaining raw material character without prohibited additives.
Prevulcanized Isoprene Rubber Latex
Special prevulcanized latex of synthetic IR for foam rubber and medical gloves, where vulcanization occurs during processing. HTS 4002.60.00.00 includes this primary liquid form as explicitly allowed under chapter note 5(a) exception.
Synthetic IR Rubber Blocks
Irregular block form of isoprene rubber for industrial compounding. Classified HTS 4002.60.00.00 as primary 'blocks of irregular shape' explicitly listed in chapter note 3.
Low Molecular Weight IR Solution
Solution of depolymerized isoprene rubber in organic solvent for specialty coatings. HTS 4002.60.00.00 permits such solutions as primary forms if retaining rubber character per chapter definition.
Cis-1,4 Polyisoprene Rubber Bale
Baled synthetic isoprene rubber (IR), a high-cis polyisoprene mimicking natural rubber properties for tire and conveyor belt production. HTS 4002.60.00.00 covers this primary form bale as unvulcanized synthetic rubber meeting chapter note 2 criteria.
IR Synthetic Rubber Powder
Fine powder form of isoprene rubber used in compounding for seals and gaskets. Classified in HTS 4002.60.00.00 as primary form powder, a permitted bulk form under chapter note 3 without disallowed additives.
Isoprene Rubber (IR) Crumb
Crumb form of synthetic isoprene rubber, a bulk primary form for recycling into new compounds. Under HTS 4002.60.00.00 as permitted 'crumbs' per chapter note 3, uncompounded.
High Ammonia IR Latex
Stabilized synthetic isoprene rubber latex with high ammonia content for carpet backing and textiles. HTS 4002.60.00.00 as primary liquid form; ammonia permitted as stabilizer per note 5(b)(iii).
