Products classified under HTS 2901.22.00.00
Polymer-Grade Propylene
High-purity propene (propylene) used as a primary feedstock in the production of polypropylene plastics for packaging, automotive parts, and consumer goods. It falls under HTS 2901.22.00.00 as a separate chemically defined acyclic unsaturated hydrocarbon. This classification applies to bulk industrial-grade propylene meeting polymerization specifications.
Refinery-Grade Propylene
Propene extracted from refinery streams, typically 90-95% purity, used for chemical synthesis including propylene oxide and cumene production. Classified under HTS 2901.22.00.00 as chemically defined propene, distinct from crude mixtures. Meets chapter note (a) for separate organic compounds.
Chemical-Grade Propylene
99%+ pure propene tailored for oxo-alcohol synthesis and acrylic acid production via propionaldehyde processes. It is a separate chemically defined acyclic unsaturated hydrocarbon under HTS 2901.22.00.00. Purity distinguishes it from refinery streams.
Propylene Monomer for Polypropylene
Ultra-high purity propene (propylene monomer) specifically for homopolymer and copolymer polypropylene production in gas-phase processes. Falls under HTS 2901.22.00.00 as pure acyclic unsaturated hydrocarbon per chapter note (a). Used in fibers, films, and injection molding.
Stabilized Propylene Gas
Propene with added polymerization inhibitor (per chapter note f) for safe transport and storage in petrochemical supply chains. Remains classified as HTS 2901.22.00.00 since stabilizer is solely for preservation. Used in downstream alkylation and metathesis.
Propylene for Cumene Production
High-specification propene used in alkylation with benzene to produce cumene, a phenol/acetone precursor. Pure acyclic unsaturated hydrocarbon under HTS 2901.22.00.00, meeting chapter purity requirements. Supplied to phenol plants worldwide.
Propylene Feedstock for Acrylonitrile
Propene for ammoxidation process to produce acrylonitrile, used in acrylic fibers and ABS plastics. Chemically defined under HTS 2901.22.00.00 as pure propene. Industrial grade with low water content.
Electronic-Grade Propylene
Ultra-pure propene (>99.99%) for semiconductor precursor synthesis and specialty polymer production. Meets HTS 2901.22.00.00 as separate chemically defined compound. Low metals and oxygenates for high-tech applications.
Propylene for Propylene Glycol
Propene feedstock for hydrolysis to propylene oxide then glycol production for antifreeze and polyester resins. Pure under HTS 2901.22.00.00 per chapter note (a). Bulk liquid under pressure.
Isomeric Pure Propene
Mixture of propene stereoisomers (per note b), chemically defined without acyclic hydrocarbon impurities. Used in specialty fine chemical synthesis under HTS 2901.22.00.00.
Propylene for Isopropyl Alcohol
Propene for sulfuric acid absorption process to IPA, used as solvent and rubbing alcohol. HTS 2901.22.00.00 as unsaturated acyclic hydrocarbon.
High-Purity Propylene USP
Pharma-grade propene for medical propellant or precursor synthesis, meeting USP standards. Still HTS 2901.22.00.00 as pure compound.
Propylene Research Grade
Lab-grade propene for R&D in organic synthesis. HTS 2901.22.00.00, small cylinders.
Refrigerated Liquid Propylene
Liquefied propene at -48°C for overseas tanker import. Pure under HTS 2901.22.00.00.
Propylene with Transport Stabilizer
Propene with anticaking stabilizer per note (f) for long-haul import. HTS 2901.22.00.00.
