The U.S. Treasury Department on Wednesday, February 25, 2026, imposed sanctions on over 30 individuals, entities, and vessels involved in facilitating illicit Iranian petroleum sales and the production of ballistic missiles and advanced conventional weapons, according to a statement released by Washington.
The sanctions target what the Treasury Department described as a “shadow fleet” of vessels used to transport Iranian oil, circumventing existing restrictions. The department alleges these entities and individuals are key enablers of Iran’s destabilizing activities in the region. The move comes after years of U.S. Sanctions targeting Iran’s energy sector and weapons programs, initially implemented following the 1979 Iranian Revolution and significantly expanded in response to concerns over its nuclear program.
According to the U.S. State Department, restrictions on activities with Iran have been in place under various legal authorities since 1979. These authorities include the National Emergencies Act (NEA) of 1976, the International Emergency Economic Powers Act (IEEPA) of 1977, and the Iran Sanctions Act (ISA), formerly known as the Iran and Libya Sanctions Act of 1996. The ISA requires annual renewal to remain in effect.
The Office of Foreign Assets Control (OFAC), the agency within the Treasury Department responsible for administering and enforcing these sanctions, has issued numerous advisories to guide compliance. Recent guidance from OFAC includes information on detecting and mitigating Iranian oil sanctions evasion, as well as advisories related to Iran’s ballistic missile procurement and unmanned aerial vehicle (UAV) activities. A 2025 advisory specifically focused on shipping and maritime stakeholders.
The U.S. Has previously imposed sanctions in response to Iranian support for groups designated as terrorist organizations, including Hezbollah, Hamas, and Palestine Islamic Jihad. Iranian support for Shia militias in Iraq and the Houthi movement in Yemen has similarly been cited as a point of contention. In 2018, the European Commission announced its intention to implement a “blocking statute” aimed at countering U.S. Sanctions, but the extent of its practical effect remains unclear.
As of February 25, 2026, the U.S. Maintains an embargo on dealings with Iran and prohibits the sale of aircraft and repair parts to Iranian aviation companies, a restriction initially imposed in 1995. The Treasury Department has not yet released a full list of the sanctioned entities and individuals, nor detailed the specific financial implications of the new measures.
