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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If greater than 99% pure and in non-liquefied form
High-purity ethylene classified as acyclic hydrocarbons under Chapter 29 when not presented as liquefied gas.
If primarily propane or butane with minor ethylene content
Mixtures dominated by saturated hydrocarbons like propane fall under propane/butane subheadings.
If imported as chemical mixtures or preparations containing ethylene
Prepared chemical binders or additives with ethylene as a component shift to Chapter 38.

Import Tips & Compliance
• Ensure cylinders or containers meet DOT/UN pressure vessel standards and include proper safety data sheets (SDS)
• Verify purity levels and provide lab analysis certificates to confirm classification as ethylene over 50%
• Avoid misclassification as natural gas liquids by documenting petrochemical production origin

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.
