Ethane/Propane Blend Gas
Ethane/propane blend gas is a gaseous mixture of ethane and propane used as petrochemical feedstock. It is not classified as natural gas or as a specific liquefied petroleum gas product, and since it is a mixture rather than a separate chemically defined compound, it falls under this tariff item for other petroleum gases.
Fuel Gas Mixtures (C3+ Hydrocarbons)
Fuel gas mixtures containing C3 and higher hydrocarbons are used as industrial fuel gas. These mixed gaseous hydrocarbons do not fit into specific categories for LPG or olefins and are derived from refining processes, making them classifiable under this tariff item as other petroleum gases in gaseous state.
High-Purity Propane Fuel Gas
High-purity propane fuel gas has at least 90% liquid volume purity and is supplied in gaseous state for residential and commercial heating. Pure propane is specifically included in heading 27.11 by Chapter Note 1, and since it is in gaseous state, it falls under this tariff item as other petroleum gases.
