April 9, 2025 | Washington, D.C. — The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) announced today a new round of sanctions targeting five Iranian companies and one individual involved in advancing Iran’s nuclear capabilities. The move reinforces the United States’ ongoing efforts to prevent Iran from developing a nuclear weapon, as outlined in National Security Presidential Memorandum 2.
The designated entities are accused of supporting the Atomic Energy Organization of Iran (AEOI) and its key affiliate, the Iran Centrifuge Technology Company (TESA), both central players in Tehran’s uranium enrichment activities.
“The Iranian regime’s reckless pursuit of nuclear weapons remains a grave threat to the United States and a menace to regional stability and global security,” said Secretary of the Treasury Scott Bessent. “Treasury will continue to leverage our tools and authorities to disrupt any attempt by Iran to advance its nuclear program.”
Centrifuge and Component Suppliers
Among those designated are Atbin Ista Technical and Engineering Company (AIT) and Pegah Aluminum Arak Company (Pegah), both based in Iran. These companies are accused of providing critical materials and procurement services to TESA, which manufactures centrifuges used for uranium enrichment.
Iranian national Majid Mosallat, the Chairman and Managing Director of AIT, is also sanctioned for overseeing procurement efforts on behalf of TESA. He is believed to have facilitated shipments of sensitive components to support Iran’s nuclear infrastructure.
Support for Nuclear Reactor Development
Three other Iranian firms—Thorium Power Company (TPC), Pars Reactors Construction and Development Company (Satra Pars), and Azarab Industries Co.—were sanctioned for their direct ties to AEOI and involvement in the development of nuclear reactor technology, including thorium-fueled reactors and components for power plants.
AEOI formed TPC in July 2023 to research thorium-fueled reactor technology, which can be used to produce fissile uranium-233. Satra Pars oversees various nuclear reactor projects, while Azarab, a major contractor in industrial and energy projects, has existing contracts to supply equipment to nuclear power plants under AEOI supervision.
Legal and Economic Impact
The sanctions were issued under Executive Order 13382, which targets proliferators of weapons of mass destruction and their delivery systems. As a result of these actions, all property and interests of the designated entities and individual that fall under U.S. jurisdiction are blocked. U.S. persons are generally prohibited from engaging in transactions with them.
Furthermore, any entity owned 50% or more by one or more of the designated parties is also subject to blocking measures. U.S. and foreign persons that violate these sanctions may face significant civil or criminal penalties.
These designations also carry implications for U.S. export controls. Transactions involving listed parties may be subject to additional restrictions under the Bureau of Industry and Security’s regulations.
