The United States has imposed fresh sanctions targeting Iran’s aviation sector as Washington intensifies its campaign to isolate Tehran economically and restrict activities it says support the Iranian regime.
The US Treasury Department announced 36 new sanctions on September 8, targeting airlines, aviation companies, cargo handlers and intermediaries accused of supporting Iran’s aviation industry. The measures extend restrictions beyond previously sanctioned carriers and include companies in countries such as Turkey, the United Arab Emirates, Malaysia and Kazakhstan.
The sanctions particularly affect Mahan Air, which has been under US restrictions for years. Washington has accused the airline of facilitating the movement of weapons, personnel and other resources linked to Iran’s Islamic Revolutionary Guard Corps.
US Treasury Secretary Scott Bessent warned foreign companies assisting Iranian airlines that they could face exclusion from the international financial system. The administration said the new measures are part of its wider “Operation Economic Outcast”, aimed at cutting Iran’s access to global finance and reducing its ability to generate revenue.
Washington also suspended three existing aviation authorisations. The move restricts certain non-US airlines from operating US-origin aircraft into Iran and limits access to some aircraft safety parts and emergency services.
The development is significant because Iran’s aviation industry has operated under US sanctions for years, contributing to difficulties in acquiring modern aircraft, spare parts and maintenance support. Analysts warn that additional restrictions could further complicate airline operations and increase pressure on an already strained sector.
Iran has criticised the broader US sanctions campaign, arguing that such measures harm the country’s economy and population. The latest action comes amid heightened tensions between Washington and Tehran and a wider confrontation involving military and economic pressure.
The United States has previously sanctioned major Iranian carriers, including Iran Air and Mahan Air, over alleged support for military activities and the transfer of sensitive materials.
The latest measures therefore represent another escalation in Washington’s strategy of using sanctions to pressure Iran, with the aviation sector now facing some of its most extensive restrictions to date.
