Compressed Natural Gas (CNG) from China
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.

Import Tips
• Verify gas composition meets natural gas standards (primarily methane) via lab analysis certificates to avoid reclassification
• Obtain pipeline interconnection approvals and ensure compliance with PHMSA regulations for high-pressure gas transport
• Declare volume in cubic meters at standard conditions; common pitfall is incorrect temperature/pressure adjustments
