About heading 2711
Petroleum gases and other gaseous hydrocarbons
Heading 2711 covers petroleum gases and other gaseous hydrocarbons, whether liquefied or in gaseous state. The heading splits first by physical state (liquefied under 2711.11 through 2711.19, gaseous under 2711.21 and 2711.29), then by which gas it is: natural gas, propane, butanes, ethylene, propylene, butylene, butadiene, ethane, or other. All declarable lines in this heading carry a general (MFN) rate of Free.
