The U.S. on Wednesday announced sanctions on an Iran-based individual and his network of companies that it accused of aiding the Middle Eastern country's regime of procuring materials for its ballistic missile program.

According to the Treasury Department, Mohammad Ali Hosseini procured processing machines for nitrile butadiene rubber (NBR) as well as an inert gas jet milling system.

"This action reinforces the United States' commitment to preventing the Iranian regime's development and use of advanced ballistic missiles," said Under Secretary of the Treasury for Terrorism and Financial Intelligence, Brian E. Nelson.

"While the United States continues to seek Iran's return to full compliance with the Joint Comprehensive Plan of Action, we will not hesitate to target those who support Iran's ballistic missile program. We will also work with other partners in the region to hold Iran accountable for its actions, including gross violations of the sovereignty of its neighbors."

Wednesday's move freezes any U.S. assets of those hit with sanctions and generally bars Americans from dealing with them. Those that engage in certain transactions with them also risk being hit with sanctions,

The companies hit with sanctions in Wednesday's action include Iran-based Jestar Sanat Delijan and Sina Composite Delijan Co. Also sanctioned was P.B. Sadr Co, which the Treasury accused of acting on behalf of Parchin Chemical Industries, an element of Iran's Defense Industries Organization also under U.S. sanctions.
