In 2018, the United States imported about 9.94 million barrels per day (MMb/d) of petroleum from nearly 90 countries. Petroleum includes crude oil, hydrocarbon gas liquids, refined petroleum products such as gasoline and diesel fuel, and biofuels including ethanol and biodiesel. Crude oil accounted for about 78% of U.S. gross petroleum imports in 2018, and non-crude oil petroleum accounted for about 22% of gross petroleum imports.

In 2018, the United States exported about 7.60 MMb/d of petroleum to about 190 countries and 4 U.S. territories, of which about 27% was crude oil and 73% was non-crude oil petroleum. The resulting net imports (imports minus exports) of petroleum were about 2.34 MMb/d.

The top five source countries of U.S. petroleum imports in 2018 were Canada, Saudi Arabia, Mexico, Venezuela, and Iraq.
