Subheadings
Products classified under HTS 2711.29.00
Propane Gas
Propane is a flammable hydrocarbon gas commonly used for heating, cooking, and as a vehicle fuel, supplied in gaseous state under pressure. It falls under HTS 2711.29.00 as a petroleum gas and other gaseous hydrocarbon that is neither liquefied petroleum gas (LPG) nor natural gas, nor ethylene, propylene, butane, or butylene. This classification applies to propane in its gaseous form at import.
Industrial Propylene Gas
High-purity propylene gas used in chemical manufacturing for plastics and synthetic fibers, delivered in gaseous state. Classified under HTS 2711.29.00 as 'other' gaseous hydrocarbons excluding specifically named olefins like pure propylene in certain contexts, but applicable here for industrial grades. Meets chapter definitions for petroleum-derived gases.
Fuel Gas Mixtures (C3+ Hydrocarbons)
Mixed gaseous hydrocarbons (C3 and higher) used as industrial fuel gas, not fitting specific LPG or olefin categories. HTS 2711.29.00 covers these 'other' petroleum gases in gaseous state, derived from refining processes. Excludes natural gas and named gases per hierarchy.
Hydrogen-Rich Refinery Off-Gas
Off-gases from petroleum refineries containing hydrogen and light hydrocarbons (C2+), used in hydrocracking processes, imported gaseous. Falls under HTS 2711.29.00 as 'other' gaseous hydrocarbons from petroleum sources, not specified elsewhere. Complies with chapter notes excluding electrical energy.
Isobutylene Gas
Isobutylene, a branched C4 olefin gas used in synthetic rubber production, supplied in gaseous state. HTS 2711.29.00 applies as 'other' gaseous hydrocarbons, excluding linear butylene but capturing branched variants not specifically named. Derived from petroleum cracking.
Ethane/Propane Blend Gas
Gaseous blend of ethane and propane for petrochemical feedstock, not qualifying as natural gas or LPG. Classified in HTS 2711.29.00 for other gaseous hydrocarbons in gaseous state from petroleum. Used in ethylene production plants.
C4+ Refinery Fuel Gas
Tail gas from refinery processes with C4+ hydrocarbons, burned as fuel in gaseous form. HTS 2711.29.00 captures these as other petroleum gases not elsewhere specified. Excludes biodiesel per chapter notes.
Methylacetylene Gas
Methylacetylene (propyne) gas used in welding torches and chemical synthesis, petroleum-derived and gaseous. Under HTS 2711.29.00 as other gaseous hydrocarbons, not fitting olefin specifics or light oils. Flammable per safety regs.
