The United States has imported a relatively small share of crude oil from Russia, but U.S. imports of petroleum products from Russia—namely, unfinished oils and fuel oil—is a larger share. U.S. refineries use imported unfinished oils and fuel oil as a supplement to crude oil in the refining process. On March 8, President Biden announced a ban on U.S. imports of petroleum, coal, and natural gas from Russia in response to Russia’s further invasion into Ukraine. The ban includes crude oil and petroleum products.
