Polybutene-1 Resin PB-1
Polybutene-1 (PB-1) is a polyolefin polymer derived from butene-1 monomer, classified under HTS 3902.90.00 as it falls within polymers of other olefins in primary forms (pellets or granules). It meets the subheading note requiring the monomer unit to contribute 95% or more by weight. Used in pipes, films, and sealants due to its flexibility and sealability.
Polyisobutylene (PIB) Gum
Polyisobutylene is a synthetic rubber-like polyolefin from isobutylene monomer, imported as viscous liquid or granules under HTS 3902.90.00 for other olefin polymers in primary forms. It qualifies as the isobutylene units exceed 95% by weight. Commonly used in chewing gum base, adhesives, and sealants.
Polymethylpentene (PMP) Pellets
Polymethylpentene, a high-clarity polyolefin from 4-methyl-1-pentene monomer, is imported in pellet form under HTS 3902.90.00 as other olefin polymers in primary forms. The monomer contributes over 95% by weight per chapter notes. Ideal for labware, medical devices, and microwave components due to heat resistance.
