As part of enforcement efforts, OFAC publishes a list of individuals, vessels, and companies owned or controlled by targeted countries or designated under programs that are not country-specific. Collectively, such vessels and companies are called Specially Designated Nationals or SDNs. Oceangoing vessels and owners, if found on the SDN list, can be of high risk to charterers if hired on a spot market.

The 10 megabyte SDN database is publicly accessible and can be found on the U.S. Treasury website.
