SITCSection 3
U.S. exports of natural gas in the gaseous state (SITC 34320) totaled $1.1B in July 2026.
Natural Gas in the Gaseous State imports of $344.0M in July 2026 ran 61% below the year-to-date monthly average of $892.0M.
Last updated: July 2026 dataPipeline-delivered natural gas — transported in its gaseous state rather than liquefied — enters the US primarily via cross-border pipeline interconnections with Canada and Mexico. Unlike LNG, gaseous-state natural gas trade is physically constrained to pipeline infrastructure, making bilateral pipeline capacity and interconnection agreements the dominant commercial and regulatory framework. DOE authorization is required for cross-border pipeline gas trade, and FERC regulates the interstate pipeline infrastructure through which imported gas flows.

Pipeline natural gas imports and exports require DOE authorization under the Natural Gas Act, similar to LNG, but the physical infrastructure — cross-border pipelines — is regulated by FERC for interstate facilities and by relevant state commissions for intrastate connections. Unlike LNG, which can be shipped to any country with a receiving terminal, gaseous-state trade is geographically fixed to existing pipeline routes, making Canada and Mexico the only practical trading partners for this commodity form.
Cross-border pipeline gas must meet the quality specifications of the receiving pipeline system, typically defined in the pipeline's tariff on file with FERC. Key parameters include heating value (BTU content), water vapor content, hydrogen sulfide limits, and inert gas concentrations. Measurement is conducted at custody transfer metering stations at or near the border, and discrepancies in measured volume or quality can trigger commercial disputes between shippers and pipeline operators.
