PANews reported on April 29 that, according to CCTV, the U.S. Treasury Department's Office of Foreign Assets Control (OFAC) released an explanatory document on April 28 stating that the U.S. prohibits individuals or entities from paying security fees to Iran for passage through the Strait of Hormuz. The document states that no entity, including U.S. individuals, U.S. financial institutions, or foreign entities owned or controlled by the U.S., may directly or indirectly pay security fees to the Iranian government or the Islamic Revolutionary Guard Corps (IRGC). OFAC indicated that non-U.S. individuals or entities paying security fees to Iran for passage through the Strait of Hormuz would also pose a significant risk of sanctions. Because the Iranian government and the IRGC are subject to U.S. sanctions citing nuclear non-proliferation and counterterrorism, foreign financial institutions and other non-U.S. individuals or entities will face sanctions if they engage in certain transactions or activities with sanctioned entities. Transactions involving certain sectors of the Iranian economy may also expose foreign individuals or entities to sanctions. On the same day, OFAC also added 17 foreign nationals and 18 foreign entities to its sanctions list related to Iran.
