The US Treasury has imposed sanctions on six more entities linked to Iran’s Mahan Air, broadening Washington’s pressure campaign against networks tied to military procurement. The move adds to existing restrictions and signals a continued effort to disrupt channels that support Iran through cross-border business relationships.

According to the available details, the latest designations cover companies and individuals in China, India, Russia and Iran. By extending sanctions across multiple jurisdictions, the US is targeting a wider web of commercial connections rather than focusing only on actors inside Iran.

Mahan Air has long drawn scrutiny from US authorities, and the new action appears aimed at limiting access to goods, services and procurement pathways connected to the airline’s broader network. The designations also fit into the Biden administration’s use of economic pressure tools, even as the wording in the report references a ramped-up "maximum pressure" approach.

For businesses, the expanded sanctions raise compliance risks across international supply chains and trade finance. Firms involved in shipping, logistics, payments or sourcing in the affected regions may face increased due diligence demands as the US tightens restrictions around Iran-linked activity.
