This rule amends the Export Administration Regulations (EAR) by imposing a license requirement on the export and reexport of any item subject to the EAR by a U.S. person or non-U.S. person to persons designated in or pursuant to Executive Order 13224 of September 23, 2001. In response to grave acts of terrorism and threats of terrorism, Executive Order 13224 blocks the property and interests in property of persons listed in an Annex to the order and persons designated by the Secretary of State or the Secretary of the Treasury pursuant to criteria set forth in the order. Executive Order 13224 also prohibits U.S. persons from engaging in any transactions with such blocked persons. The Department of the Treasury's Office of Foreign Assets Control (OFAC) announces the names of persons designated pursuant to Executive Order 13224 in the Federal Register and includes such persons in a listing of persons subject to various sanctions programs administered by OFAC. The Department of State also announces the names of foreign persons designated pursuant to Executive Order 13224 in the Federal Register. All persons designated in or pursuant to Executive Order 13224 are identified by the bracketed initials [SDGT] in the Department of Treasury listing and are also known as Specially Designated Global Terrorists (SDGTs). This rule also amends the EAR by expanding reexport controls on Specially Designated Terrorists (SDTs) and Foreign Terrorist Organizations (FTOs). OFAC also includes SDTs and FTOs in the Department of Treasury listing and identifies them by the bracketed initials [SDT] and [FTO], respectively.
