On 10 January 2020, in response to missile attacks by the Iranian military targeting two U.S. bases in Iraq, the United States Department of the Treasury, Office of Foreign Assets Control (OFAC) designated a number of senior Iranian military leaders, Iranian metals companies, as well as third-country entities and a vessel on the List of Specially Designated Nationals and Blocked Persons (SDN List). While the Iranian metals sector has been a target of U.S. sanctions for some time, these sanctions are the first to be issued under the May 2019 Executive Order 13871, which targets the Iranian iron, steel, aluminum, and copper sectors.
