C4+ Refinery Fuel Gas from United States
C4+ refinery fuel gas is a tail gas from petroleum refining processes, consisting of hydrocarbons with four or more carbon atoms, and is burned as fuel in its gaseous state. It falls under tariff item 2711.29.00 as 'other' petroleum gases and gaseous hydrocarbons not elsewhere specified, since it does not qualify as natural gas or liquefied petroleum gas. The chapter notes exclude separate chemically defined organic compounds, but this mixed gas is not such a compound.

Import Tips
• Ensure the gas is in gaseous state at import and not liquefied, as that would fall under a different heading
• Provide a certificate of analysis to confirm the hydrocarbon composition and that it is not a separate chemically defined compound
• Verify with CBSA that the product is not classified as a waste oil under heading 27.10
