The U.S. Treasury's Office of Foreign Assets Control removed an Iranian industrial corporation and its subsidiary from its Specially Designated Nationals list on October 8, after the businesses challenged their designation in U.S. court. Mammut Industrial Group and its subsidiary, Mammut Diesel, had been designated in September 2020 for allegedly supplying Iran’s missile programs. Three individuals associated with the companies had also been designated at the time but were delisted in July 2021. A Treasury Department spokesperson claimed that the delistings were unrelated to negotiations to return Iran and the United States to compliance with the JCPOA nuclear agreement.
