The sanctions target eight entities, one vessel and one person for their alleged role in providing sensitive machinery for Tehran’s defence industry.

“The United States remains resolved to disrupt any effort by Iran to procure the sensitive, dual-use technology, components, and machinery that underpin the regime’s ballistic missile, unmanned aerial vehicle, and asymmetric weapons programs,” U.S. Treasury Secretary Scott Bessent said in a statement announcing the action.

Two of the entities include shipping companies based in Hong Kong: Unico Shipping Co Ltd and Athena Shipping Co Ltd, the statement said.

The Treasury Department on Friday also issued counterterrorism-related sanctions targeting Yemen’s Iran-aligned Houthis over alleged illicit oil trading and shipping, it said in a separate statement.

Those sanctions target four individuals, 12 entities, and two vessels over imported oil and other illicit goods to support the Houthis, the department said.
