Liquefied Natural Gas (LNG)

Importers of LNG must obtain authorization from the US Department of Energy (DOE) under the Natural Gas Act. Imports from countries with which the US has a free trade agreement receive automatic authorization, while imports from non-FTA countries require a separate discretionary authorization. FERC also regulates the siting and operation of LNG import terminals.

Trinidad and Tobago has historically been the top LNG supplier to the US, followed by Mexico and Qatar. Canada and South Korea also appear among the leading origins, though the US LNG import market has shifted significantly as domestic production has grown.
