On January 12, the U.S. Treasury Department’s Office of Foreign Assets Control (OFAC) issued Counter Terrorism General License (GL) 21B, “Authorizing Limited Safety and Environmental Transactions Involving Certain Vessels,” to authorize limited safety and environmental transactions involving certain persons or vessels that are normally prohibited by the Global Terrorism Sanctions Regulations (GTSR) through 12:01 a.m. EST, April 13, 2023. OFAC explained that such transactions are authorized as long as payments to a blocked person are made into a blocked account in accordance with the GTSR. A list of authorized blocked persons and vessels listed on OFAC’s Specially Designated Nationals and Blocked Persons List is also included. OFAC also amended related FAQ 1097 to provide additional clarification on permitted transactions.
