Products classified under HTS 2711.14.00.30
Liquefied 1-Butene (Butylene-1)
Liquefied 1-butene is a petroleum-derived gaseous hydrocarbon with the formula C4H8, classified under HTS 2711.14.00.30 as butylene due to its butylene chemical structure. It is commonly used as a monomer in the production of polyethylene and other polymers.
Liquefied Isobutylene (2-Methylpropene)
Liquefied isobutylene, also known as 2-methylpropene, is a branched C4 olefin gaseous hydrocarbon liquefied under pressure, falling under HTS 2711.14.00.30 as butylene. It serves as a key intermediate in producing methacrylic acid, butyl rubber, and fuels.
Liquefied n-Butene (cis/trans-2-Butene Mix)
Liquefied n-butene, primarily a mixture of cis- and trans-2-butene isomers, is a straight-chain butylene gas classified under HTS 2711.14.00.30. It is utilized in the synthesis of maleic anhydride and as a fuel gas component.
Liquefied Raffinate-2 Butylene Stream
Liquefied raffinate-2 is a refinery stream containing 70-90% butylene (mixed isomers) after butadiene extraction, classified as butylene under HTS 2711.14.00.30. Primarily used in gasoline blending and alkylation processes.
Polymer-Grade Liquefied Butylene (C4 Olefin Mix)
Polymer-grade liquefied butylene is a high-purity C4 olefin mixture (85%+ total butylene isomers) for polyethylene co-monomer use, falling under HTS 2711.14.00.30. Specifications ensure low impurities for resin production.
