Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If liquefied for export
Liquefaction for overseas transport shifts classification to liquefied natural gas.
If containing significant petroleum gases
Blends exceeding natural gas purity may classify as crude petroleum oils.
If chemically treated as preparations
Additives making it a chemical preparation move it out of natural gas heading.

Import Tips & Compliance
• Provide heating value (BTU/scf) and Wobbe index certifications to confirm pipeline specs
• Coordinate with FERC for cross-border pipeline entry points and capacity rights
• Watch for misdeclaration as 'associated gas' which may trigger different valuation rules

Compressed Natural Gas (CNG)
Compressed natural gas is natural gas primarily composed of methane, compressed to high pressure for storage and transportation in gaseous state. It falls under HTS 2711.21.00.00 as natural gas in gaseous state, distinct from liquefied forms. Used mainly as a vehicle fuel and industrial feedstock.
Dry Natural Gas
Dry natural gas has had natural gas liquids removed, consisting mainly of methane in gaseous form. It qualifies under HTS 2711.21.00.00 as unliquefied natural gas for direct pipeline use. Primarily used in residential and commercial heating.
Stranded Natural Gas
Stranded natural gas from remote fields, transported in gaseous form via pipeline or truck to markets. Meets HTS 2711.21.00.00 criteria as unprocessed natural gas in gaseous state. Reduces flaring in production.
High-Pressure Natural Gas for Vehicles
Natural gas compressed to 3,000-3,600 psi for use in CNG vehicle fueling stations, remaining in gaseous state. Falls under HTS 2711.21.00.00 as natural gas, not processed into liquid. Supports clean transportation fuels.
Biogenic Natural Gas
Biogenic natural gas from landfills or digesters, primarily methane in gaseous state, treated as equivalent to fossil natural gas. Classified under HTS 2711.21.00.00 regardless of biological origin. Used in renewable energy applications.
Sweet Natural Gas
Sweet natural gas with low hydrogen sulfide (<4 ppm), processed for direct use in gaseous state. Under HTS 2711.21.00.00 as standard natural gas specification. Preferred for combustion turbines.
