The United States on Tuesday imposed sanctions on a network that includes a Turkey-based company accused of supplying materials used in Iran’s ballistic missile program, as part of broader measures targeting 14 individuals, entities and aircraft linked to Tehran’s weapons procurement efforts.
The Treasury Department’s Office of Foreign Assets Control (OFAC) designated Emti Fiber Textile Import Export Trade Limited Company for completing hundreds of shipments of cotton linters to Iran-based Pardisan Rezvan Shargh International Private Joint Stock Company. OFAC records list the company at an address in Esenyurt district of İstanbul and say it was established on October 31, 2023.
Treasury said cotton linters are processed into nitrocellulose, which is used to improve the performance of solid propellant rocket motors commonly used for ballistic missiles.
Pardisan Rezvan Shargh had already been sanctioned on December 30, 2025, for acting on behalf of Iranian national Mostafa Rostami Sani, who Treasury said procured dozens of metric tons of sodium perchlorate for Parchin Chemical Industries, an element of Iran’s Defense Industries Organization. Treasury said the Defense Industries Organization was designated in March 2007 and Parchin Chemical Industries in July 2008, with both also subject to UN asset freezes.
Treasury said the latest action also targeted three individuals linked to the Iran-based Pishgam Electronic Safeh Company, which it said procured thousands of servomotors found in Iranian Shahed-136 drones. Treasury said Iran is increasingly relying on Shahed-series one-way attack drones to target the United States and its allies, including energy infrastructure in the region, as Washington seeks to deplete Tehran’s ballistic missile inventories.
The sanctions package also included several people and entities linked to Iran’s Mahan Air, which Treasury said has been involved in the procurement and transport of unmanned aerial vehicle systems and weapons to and from Iran. Treasury said entities in the United Arab Emirates, Turkey, Iraq, China, Thailand, Pakistan and India had provided material, logistical and other support to Mahan Air flights.
Treasury Secretary Scott Bessent said the United States would continue to “follow the money” and target those enabling Iran’s weapons programs.
The move came six days after Treasury announced another Iran-related sanctions package targeting an oil smuggling and gold scheme. In that case, Treasury said Iranian oil moved to Venezuela in exchange for gold, which was then transferred on Mahan Air flights to Hezbollah figures in Tehran and later smuggled to Turkey for sale.
Treasury said Tuesday’s action was its fifth round of nonproliferation sanctions since the September 27, 2025, reimposition of UN sanctions and other restrictions on Iran. It said the measures were part of the implementation of National Security Presidential Memorandum 2, signed on February 4, 2025, which directs the US government to intensify pressure on Iran’s missile, nuclear and military procurement networks.
