Specially Designated Nationals List (SDN)

The Specially Designated Nationals (SDN) List is a list maintained by the U.S. Treasury Department's Office of Foreign Assets Control (OFAC). It includes individuals, organizations, and entities that are subject to economic sanctions because of their involvement in activities like terrorism, drug trafficking, or serious human rights abuses. Being named on this list means that assets of these individuals or groups in the U.S. are frozen, and Americans cannot do business with them. The SDN List helps the U.S. government enforce foreign policy and national security objectives by restricting financial transactions and economic interactions with these designated parties.
