Products classified under HTS 3902.90.00
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.
Poly-4-methyl-1-pentene Granules
Granular poly-4-methyl-1-pentene (TPX) is a semicrystalline olefin polymer used in optical and high-temp applications, classified in HTS 3902.90.00 for primary form olefin polymers beyond propylene. Meets 95% monomer threshold. Offers low density and high transparency.
High-Density Polybutene Pellets
High-density polybutene resin pellets for piping and hot-melt adhesives are olefin polymers under HTS 3902.90.00, as butene-derived in primary granular form with >95% monomer content. Provides superior creep resistance and flexibility.
Isotactic Polybutene Powder
Isotactic polybutene powder, a stereoregular olefin homopolymer, is classified under HTS 3902.90.00 for other olefins in primary powder form suitable for compounding. Monomer purity exceeds chapter note requirements. Applied in sealants and electrical insulation.
Copolymer Polybutene PB-0300 MFI Pellets
PB-0300 copolymer polybutene pellets with 0.3 g/10min MFI for film blowing, classified as other olefin polymers in HTS 3902.90.00 since butene units predominate over 95%. Used in stretch films and medical packaging.
Liquid Polybutene L-14E
Liquid polybutene L-14E (viscosity 140 cSt) is a low molecular weight olefin polymer imported under HTS 3902.90.00 for use in lubricants and caulks. Isobutylene monomer >95% by weight in primary liquid form.
TPX MX002 Polyolefin Resin
TPX MX002 is a clarified polymethylpentene resin grade for injection molding, under HTS 3902.90.00 as primary form polymer of other olefins. Exceptional clarity and release properties for food containers.
Polyoctene Resin Pellets
Polioctene resin from 1-octene monomer provides elastomer-like properties in pellet form, classified HTS 3902.90.00 for other olefin primary polymers meeting purity notes. Used in tire compounds and wires.
Vestoplast 101 Polybutene Hot-Melt
Vestoplast 101 amorphous polybutene for hot-melt adhesives, imported as primary polymer pellets under HTS 3902.90.00. Butene-based with >95% monomer content per notes.
Indopol H-1500 Polybutene
Indopol H-1500 high-viscosity polybutene for industrial lubricants, HTS 3902.90.00 as primary liquid olefin polymer. PI equivalent with controlled polydispersity.
Plexar PX3190 Olefin Modifier
Plexar PX3190 maleic anhydride grafted polyolefin for adhesion promotion, classified HTS 3902.90.00 as chemically modified olefin polymer per note (a)(3) 'other'. Primary pellet form.
Duraflex PB8400 Polybutene
Duraflex PB8400 medium MFI polybutene for blow molding pipes, under HTS 3902.90.00 primary olefin polymer. Balanced flexibility/stiffness.
Hybrar 7310SE Polyolefin Block Copolymer
Hybrar 7310SE styrenic block copolymer with olefin midblock, classified HTS 3902.90.00 as predominant olefin polymer per note (a)(4). Primary form for asphalt modification.
