Products classified under Tariff item 2901.22
Chemical-Grade Propylene
Chemical-grade propylene is a separate chemically defined acyclic unsaturated hydrocarbon, specifically propene, with a purity of 99% or higher. It is used as a feedstock in the production of oxo-alcohols and acrylic acid, and qualifies under tariff item 2901.22.00 as propene (propylene).
2901.22.00Electronic-Grade Propylene
Electronic-grade propylene is ultra-pure propene (greater than 99.99% purity) used in semiconductor precursor synthesis and specialty polymer production. It is a separate chemically defined compound, meeting the requirements of tariff item 2901.22.00 for propene (propylene).
2901.22.00High-Purity Propylene USP
High-purity propylene USP is pharma-grade propene meeting United States Pharmacopeia standards, used as a medical propellant or precursor in synthesis. It is a separate chemically defined compound and falls under tariff item 2901.22.00 as propene (propylene).
2901.22.00Isomeric Pure Propene
Isomeric pure propene is a mixture of propene stereoisomers, chemically defined and free of acyclic hydrocarbon impurities. It is used in specialty fine chemical synthesis and qualifies under tariff item 2901.22.00 as propene (propylene) per chapter note 1(b).
2901.22.00Polymer-Grade Propylene
Polymer-grade propylene is high-purity propene used as a primary feedstock in polypropylene production for packaging, automotive parts, and consumer goods. It is a separate chemically defined acyclic unsaturated hydrocarbon, qualifying under tariff item 2901.22.00 as propene (propylene).
2901.22.00Propylene Feedstock for Acrylonitrile
Propylene feedstock for acrylonitrile is propene used in the ammoxidation process to produce acrylonitrile, which is used in acrylic fibers and ABS plastics. It is a separate chemically defined compound, meeting the requirements of tariff item 2901.22.00 as propene (propylene).
2901.22.00Propylene for Cumene Production
Propylene for cumene production is high-specification propene used in alkylation with benzene to produce cumene, a precursor for phenol and acetone. It is a pure acyclic unsaturated hydrocarbon, qualifying under tariff item 2901.22.00 as propene (propylene).
2901.22.00Propylene for Isopropyl Alcohol
Propylene for isopropyl alcohol is propene used in the sulfuric acid absorption process to produce isopropyl alcohol, which is used as a solvent and in rubbing alcohol. It is a separate chemically defined unsaturated acyclic hydrocarbon, falling under tariff item 2901.22.00 as propene (propylene).
2901.22.00Propylene for Propylene Glycol
Propylene for propylene glycol is propene feedstock used in hydrolysis to produce propylene oxide and then glycol for antifreeze and polyester resins. It is a pure acyclic unsaturated hydrocarbon, qualifying under tariff item 2901.22.00 as propene (propylene).
2901.22.00Propylene Monomer for Polypropylene
Propylene monomer for polypropylene is ultra-high purity propene specifically for homopolymer and copolymer polypropylene production in gas-phase processes. It is a separate chemically defined acyclic unsaturated hydrocarbon, falling under tariff item 2901.22.00 as propene (propylene).
2901.22.00Propylene Research Grade
Propylene research grade is lab-grade propene for R&D in organic synthesis, supplied in small cylinders. It is a separate chemically defined compound, qualifying under tariff item 2901.22.00 as propene (propylene).
2901.22.00Propylene with Transport Stabilizer
Propylene with transport stabilizer is propene with an added anti-caking agent necessary for preservation or transport, per chapter note 1(f). It remains classified under tariff item 2901.22.00 as propene (propylene) since the stabilizer is solely for safety or transport.
2901.22.00Refinery-Grade Propylene
Refinery-grade propylene is propene extracted from refinery streams, typically 90-95% purity, used for chemical synthesis including propylene oxide and cumene production. It is classified under tariff item 2901.22.00 as propene (propylene), distinct from polymer-grade due to lower purity.
2901.22.00Refrigerated Liquid Propylene
Refrigerated liquid propylene is liquefied propene at -48°C for overseas tanker import. It is a pure acyclic unsaturated hydrocarbon, qualifying under tariff item 2901.22.00 as propene (propylene).
2901.22.00Stabilized Propylene Gas
Stabilized propylene gas is propene with an added polymerization inhibitor, per chapter note 1(f), for safe transport and storage in petrochemical supply chains. It remains classified under tariff item 2901.22.00 as propene (propylene) since the inhibitor is solely for preservation.
