Liquefied Ethylene Gas
Liquefied ethylene (C2H4) is a key petrochemical feedstock used primarily in the production of polyethylene plastics and other chemicals. It falls under HTS 2711.14.00 as a liquefied petroleum gas consisting of ethylene, meeting the classification for unsaturated hydrocarbons in gaseous form under pressure.
Liquefied Propylene (Polymer Grade)
Polymer-grade liquefied propylene (C3H6) is high-purity propylene liquefied under pressure, used mainly for polypropylene resin manufacturing. Classified under HTS 2711.14.00 due to its status as liquefied unsaturated hydrocarbon gas.
Liquefied Butylene Gas (Mixed Isomers)
Liquefied butylene (C4H8), including 1-butene, 2-butene, and isobutylene isomers, used in synthetic rubber and plastics production. HTS 2711.14.00 covers these as liquefied butylene unsaturated hydrocarbons.
Liquefied Propylene-Propane Mix (60/40)
A liquefied mixture containing 60% propylene and 40% propane, used as chemical feedstock. Classified under HTS 2711.14.00 because propylene (unsaturated) is the principal component among named gases.
Polymerization-Grade Liquefied Butadiene Mix
Liquefied C4 stream with 40-60% 1,3-butadiene plus butylenes, inhibited for rubber polymerization. Principal butadiene content places it in HTS 2711.14.00.
Liquefied Propylene for Acrylic Acid Production
Liquefied propylene feedstock for oxidation to acrylic acid and acrylates. Chemical-grade purity qualifies under HTS 2711.14.00 as liquefied propylene.
