Specially Designated Nationals and Other Restricted Persons

The U.S. Department of Treasury also designates certain persons and entities as “Specially Designated Nationals” or “SDNs” for narcotics trafficking, weapons proliferation, terrorism, and other reasons. Columbia faculty and staff should not engage in any transactions or dealings with SDNs unless cleared in advance with the Office of the General Counsel (OGC).

Refer to the Specially Designated Nationals List in the U.S. Department of Treasury's website, which is updated periodically.

Under U.S. criminal laws targeting terrorism, as amended by the U.S.A. Patriot Act, it is also violation of U.S. law to provide “material support” to an organization engaged in terrorist activity. Material support is broadly defined and includes training and other services. Organizations and individuals appearing on this list are also included on the SDN list.

When entering into discussions regarding a possible transaction with a proposed collaborator, vendor, contractor, employee, service provider, or other third party, it is critical to check the SDN list for the name of the person or entity with whom the program is dealing. In addition, it is important to check, also periodically, other U.S. restricted party lists known as:

Denied Persons List

Unverified List

Entity List

Debarred List

Many of these searches can be done through a single commercially-available software application that is licensed to Columbia. Columbia’s central administration has the tools to assist you with the appropriate screenings. Should you require assistance with this, contact Global Support.
