Products classified under HTS 3902.90.00.50
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.
High MW Polyisobutene Pellets
High molecular weight polyisobutene pellets (>95% isobutene units) for asphalt modification and sealants, under HTS 3902.90.0050 as primary 'other' olefins. Its viscosity index makes it ideal for industrial modifiers. Meets strict polymer purity notes.
Polyoctene Elastomer Resin
PolYOCTene, a 1-octene based elastomer resin in primary form, classified HTS 3902.90.0050 for other olefin polymers with predominant octene monomer. Used in tire compounds and wires for elasticity. Subheading (a)(4) applies for non-dominant specific olefins.
Cyclic Olefin Copolymer COC Pellets
Cyclic olefin copolymer (COC) pellets from norbornene and ethylene, classified by predominant monomer under HTS 3902.90.0050 as other olefins if norbornene dominates. High purity for optical media and medical packaging. Note (a)(4) governs blend classification.
Poly(3-methyl-1-butene) Granules
Poly(3-methyl-1-butene) granules, a specialty olefin polymer (>95% named monomer), under HTS 3902.90.0050 primary forms. Used in lightweight molded parts. Fits poly-prefix rule in notes.
1-Hexene Polymer Pellets
1-Hexene homopolymer pellets for films, HTS 3902.90.0050 other olefins primary form. >95% hexene units per note (a)(1).
Poly(1-pentene) Resin
Poly(1-pentene) resin granules, primary form under 3902.90.0050 for other olefins. Used in elastomers.
Norborene Olefin Polymer
Norborene-based olefin polymer pellets, classified 3902.90.0050 other primary.
Butene-Propylene Random Copolymer Granules
Random copolymer granules with butene predominant, HTS 3902.90.0050 other olefins.
High Cis-1,4 Polybutadiene Powder
High cis polybutadiene in primary powder form, olefin polymer under 3902.90.0050 if meeting notes.
