U.S. exports of natural gas, gaseous state (HS 271121) totaled $1.1B in July 2026.
Natural Gas, 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 dataGaseous natural gas — transported by pipeline rather than as LNG — enters the US almost exclusively from Canada, which shares an extensive cross-border pipeline network with the US, making this one of the most infrastructure-dependent commodity flows in North American trade. Mexico also appears among the top suppliers, though the US is a net exporter to Mexico via pipeline; the presence of Mexico in import data reflects bidirectional flows at certain border points. The single 10-digit line (2711210000) reflects the commodity's homogeneity at the tariff level, with commercial differentiation occurring through pipeline tariffs, gas quality specifications, and FERC-regulated transportation agreements rather than HTS subdivisions.

Yes. Importers of natural gas by pipeline must hold a blanket or long-term import authorization from the Department of Energy (DOE) Office of Fossil Energy and Carbon Management under the Natural Gas Act. Imports from Canada, a free-trade-agreement partner, qualify for a blanket authorization that is generally granted without a public interest review, but the authorization must be in place before commercial flows begin. FERC also regulates the pipeline infrastructure used to transport the gas.
Pipeline operators publish tariff schedules that specify acceptable ranges for heating value (BTU content), inert gas content (CO2, nitrogen), water vapor, and hydrogen sulfide. Gas that does not meet the receiving pipeline's quality specifications may be rejected at the interconnect or require conditioning before entry. Importers should confirm that the gas stream from the foreign supplier meets the downstream pipeline's tariff specifications, as quality disputes can delay or block delivery independent of customs clearance.
