SDN stands for specially designated national. The Office of Foreign Asset Control (OFAC) places individuals and entities on this list for national security, foreign policy, and sanctions policy objectives. If someone is placed on the list, it means they have been acting against the foreign policy and sanctions policy of the United States and have effectively been walled off from the international marketplace, particularly the U.S. financial system. As the U.S. economy is a major player in the international business market, placement on the SDN list makes it exceptionally difficult to engage in international transactions, particularly in U.S. dollars.
