Polybutene-1 Resin PB-1
Polybutene-1 (PB-1) is a high-molecular-weight polymer of butene-1, classified under HTS 3902.90.0050 as an 'other' olefin polymer in primary form (pellets or granules) where the butene-1 monomer exceeds 95% by weight. It is used in sealants, hot-melt adhesives, and pipe applications due to its flexibility and sealing properties. This falls into the 'Other' subheading after specific polypropylene and ethylene copolymers.
Polyisobutylene Rubber PIB
Polyisobutylene (PIB) is a synthetic rubber polymer derived from isobutylene monomer, imported in primary pellet form under HTS 3902.90.0050 as 'other' olefin polymers. With isobutylene comprising over 95% by weight, it meets subheading note (a)(1) criteria. Used in chewing gum bases, adhesives, and sealants for its tackiness and impermeability.
Polymethylpentene PMP Resin
Polymethylpentene (PMP), or poly(4-methyl-1-pentene), is a high-clarity olefin polymer imported as granules under HTS 3902.90.0050, classified as 'other' due to its specific 4-methyl-1-pentene monomer (>95% by weight). Known for heat resistance and transparency, it's used in labware, medical devices, and food packaging. Fits Chapter 39 subheading notes for non-polypropylene/non-ethylene olefins.
Poly(1-butene) Pipe Grade Resin
High-density poly(1-butene) resin for piping applications, classified in HTS 3902.90.0050 as other olefin polymers in primary granular form with >95% 1-butene monomer units. It offers superior creep resistance and flexibility for plumbing and gas pipes. Subheading notes place it in 'Other' after polypropylene specifics.
Isotactic Polybutene Granules
Isotactic polybutene granules, a stereoregular polymer of butene with high crystallinity, fall under HTS 3902.90.0050 as 'other' primary olefin polymers (>95% butene content). Used in films and molded parts for its strength and chemical resistance. Classified per note (a)(1) for named poly- prefixes.
4-Methyl-1-Pentene Copolymer Pellets
Pellets of 4-methyl-1-pentene copolymer where the named monomer predominates by weight, classified under HTS 3902.90.0050 as other olefin polymers not specifically named. Used in high-temperature films and containers. Follows subheading note (a)(4) for predominant monomer rule.
