Compressed Natural Gas (CNG)
Compressed natural gas (CNG) is natural gas, primarily methane, that has been compressed to high pressure for storage or transport but remains in a gaseous state. It is used as a fuel for vehicles or for industrial applications where pipeline delivery is not feasible. CNG is classified under this tariff item because it is natural gas in gaseous state, not liquefied.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the natural gas is liquefied
Liquefied natural gas (LNG) is classified separately under heading 27.11, as it is in a liquid state.

Import Tips & Compliance
• Verify that the CNG is not liquefied and remains gaseous at ambient temperature, as liquefied natural gas falls under a different tariff item
• Provide documentation on the compression pressure and methane purity
• Ensure compliance with Canadian transportation of dangerous goods regulations for high-pressure gas

Biogenic Natural Gas
Biogenic natural gas is methane produced from the decomposition of organic matter in landfills or digesters, captured and treated to pipeline quality. It remains in a gaseous state and is chemically identical to fossil natural gas, consisting primarily of methane. Under the Customs Tariff, it is classified as natural gas in heading 27.11, as the chapter does not exclude gases of biological origin.
Dry Natural Gas
Dry natural gas is natural gas from which natural gas liquids such as ethane, propane, and butane have been removed, leaving mainly methane. It is delivered in a gaseous state through pipelines for residential, commercial, and industrial use. This product falls under this tariff item as it is natural gas in gaseous state, not liquefied or otherwise processed.
High-Pressure Natural Gas for Vehicles
High-pressure natural gas for vehicles is natural gas compressed to pressures typically between 3,000 and 3,600 psi for use in compressed natural gas (CNG) vehicles. It remains in a gaseous state and is not liquefied, making it classifiable as natural gas under this tariff item. This product supports clean transportation fuel applications.
Pipeline-Quality Natural Gas
Pipeline-quality natural gas is natural gas that has been processed to meet transmission pipeline standards, with impurities such as water, sulfur, and carbon dioxide removed. It consists mainly of methane and is delivered in a gaseous state through pipelines. This product is classified under this tariff item as natural gas in gaseous state, excluding liquefied forms.
Stranded Natural Gas
Stranded natural gas is natural gas from remote fields that cannot be transported via pipeline due to distance or lack of infrastructure, so it is moved in gaseous form via truck or compressed for transport. It remains in a gaseous state and consists mainly of methane. This product falls under this tariff item as natural gas in gaseous state, not liquefied.
Sweet Natural Gas
Sweet natural gas is natural gas with low hydrogen sulfide content, typically less than 4 ppm, making it suitable for direct use in combustion turbines and other applications without extensive treatment. It remains in a gaseous state and consists mainly of methane. This product is classified under this tariff item as natural gas in gaseous state, as it is not liquefied or chemically altered.
