This Specially Designated Nationals and Blocked Persons List (“SDN List”) is updated frequently and at irregular intervals to incorporate changes reflected in notices of blocking, designation, identification, and delisting actions, all of which are published in the Federal Register. The SDN List is available in a variety of formats for review on, or download from, the following location on OFAC's Web site: http://www.treasury.gov/sdn. Members of the public may also sign up through OFAC's Web site to receive e-mail notifications of changes to the SDN List.

In addition to accessing information through OFAC's Web site, the public may contact OFAC's Compliance Division, at 202/622-2490 or 800/540-6322 (toll-free), for information on blocking, designation, identification, and delisting actions. The public also may contact OFAC in writing at the following address: Office of Foreign Assets Control, U.S. Department of the Treasury, 1500 Pennsylvania Avenue, NW., Washington, DC 20220.

4. Abbreviations. “a.k.a.” means “also known as”; “d.b.a.” means “doing business as”; “f.k.a.” means “formerly known as”; “IMO” means “International Maritime Organization”; “n.k.a.” means “now known as”; “DOB” means “date of birth”; “DWT” means “deadweight”; “GRT” means “Gross Registered Tonnage”; “POB” means “place of birth”.

5. Notices of blocking, designation, identification, and delisting actions are published in the Federal Register frequently and at irregular intervals. Updated information on OFAC blocking, designation, identification, and delisting actions is provided on OFAC's Web site (http://www.treasury.gov/ofac). In addition, such information is incorporated on an ongoing basis into OFAC's SDN List, which is available for review on, or download from, the following location on OFAC's Web site: http://www.treasury.gov/sdn. Please call OFAC's Compliance Division with questions about OFAC-administered sanctions programs, including current electronic sources of OFAC information: 202/622-2490 or 800/540-6322 (toll-free). Updated information on OFAC designations and other OFAC actions should be consulted before engaging in transactions that may be prohibited by the economic sanctions programs in chapter V.

6. Specific licenses previously issued by OFAC may include references to appendix A or appendix B to 31 CFR chapter V. OFAC hereby notifies persons who have been issued specific licenses by OFAC that any reference to appendix A to 31 CFR chapter V or Appendix B to 31 CFR chapter V in an outstanding specific license shall be read to refer to the SDN List. The SDN List is available for review on or download from the following location on OFAC's Web site: http://www.treasury.gov/sdn.

7. The SDN List incorporates the names of vessels owned by blocked persons, which are themselves blocked. SDN List entries for blocked vessels, which include the notation “(vessel),” are incorporated in alphabetical order into the SDN List. In addition, these entries are segregated into a separate sub-section of the SDN List under the heading “(vessels).” Except in limited circumstances, financial institutions are instructed to reject any funds transfer referencing a blocked vessel and must notify OFAC, preferably via facsimile at 202/622-2426 with a copy of the payment instructions, that funds have been returned to remitter due to the possible involvement of a blocked vessel in the underlying transaction. See § 501.604(b)(1) of this chapter. Financial institutions should contact OFAC's Compliance Division, at 202/622-2490 or 800/540-6322 (toll-free), for further instructions should the name of a blocked vessel appear in shipping documents presented under a letter of credit or if noticed in a documentary collection. Blocked vessels must themselves be physically blocked should they enter U.S. jurisdiction. Freight forwarders and shippers may not charter, book cargo on, or otherwise deal with blocked vessels.

8. The SDN List includes the names of persons identified as the Government of Iran or an Iranian financial institution and other persons whose property and interests in property are blocked pursuant to § 560.211 of the Iranian Transactions and Sanctions Regulations, 31 CFR part 560 (ITSR). The SDN List entries for such persons include the identifier “[IRAN].” U.S. persons are advised to review 31 CFR part 560 prior to engaging in transactions involving the persons included on the SDN List with the identifier “[IRAN].” U.S. persons are further cautioned that persons identified as the Government of Iran or an Iranian financial institution and any other person whose property and interests in property are blocked pursuant to 31 CFR 560.211 also may be designated or blocked pursuant to other sanctions programs administered by OFAC. The SDN List entry for such a person may include—in addition to the identifier “[IRAN]”—identifier(s) for the other sanctions program(s) pursuant to which the person is listed on the SDN List. Moreover, the prohibitions set forth in the ITSR, and the compliance obligations, with respect to persons who meet the definition of the Government of Iran in § 560.304 of the ITSR or the definition of Iranian financial institution in § 560.324 of the ITSR apply regardless of whether such persons are identified on the SDN List.
