The US Department of the Treasury has widened sanctions against a shipping network allegedly controlled by Mohammad Hossein Shamkhani, targeting additional companies and vessels accused of moving goods to and from Iran while circumventing existing sanctions, according to Ship & Bunker.
According to Ship & Bunker, the announcement was made by the Treasury on Tuesday, with the US Treasury’s Office of Foreign Assets Control (OFAC) leading the designations.
Companies and Vessels Named
OFAC designated Singapore-based Sea Lead Shipping Pte. Ltd. along with its subsidiaries located in the UAE, Marshall Islands and India, Ship & Bunker reports. The report states that OFAC alleged these companies managed container shipping operations carrying both legitimate and illicit cargoes, including shipments connected to the Iran-backed Houthis in Yemen.
Additional firms sanctioned include Volta Shipping Services, We Freight Shipping and Sai Wan Shipping, as well as companies registered in the Marshall Islands, Hong Kong, St Kitts and Nevis, and the UAE, according to Ship & Bunker.
Among the vessels named as blocked property are the container ships Shenton Way, Tanjong Pagar 1 and Paya Lebar, along with several cargo vessels reportedly operating between Iran and Russia in the Caspian Sea, Ship & Bunker notes. The tankers Darika and Virent were also sanctioned, with OFAC alleging they transported Russian petroleum products on behalf of the Shamkhani network, per the report.
Scope of the Sanctions
According to Ship & Bunker, the sanctions block any US-based assets held by the designated companies and vessels, and generally prohibit US persons from conducting business with them.
Does This Matter to You?
Expanded sanctions targeting shipping networks and vessel owners can affect counterparty due diligence, chartering decisions, and compliance screening across the maritime supply chain. Companies and vessels named in OFAC actions become subject to restrictions on US-linked assets and transactions, which may influence decisions by charterers, financiers, insurers and trading counterparts who interact with the shipping networks or vessels involved.
