Special Designated Nationals (SDN) Lists

Specially Designated Nationals (SDN) Lists are official lists maintained by the U.S. Department of the Treasury that identify individuals, companies, and organizations involved in activities that threaten national security, foreign relations, or economic interests. Being on this list means that American individuals and businesses are prohibited from engaging in transactions or conducting business with those listed. The designation is often related to issues like terrorism, drug trafficking, or violations of international sanctions. The purpose is to prevent illicit activities and protect U.S. interests by freezing assets and restricting interactions with the designated entities.
