DescriptionThe vessel has been implicated in the transportation of Iranian oil, in particular transporting more than one million barrels of Iranian oil to China, which it received from the tanker IMO 9418078, sanctioned by the United States on December 19, 2024. Iran’s shadow fleet relies on little-known ship management companies to operate its tanker fleet, which Tehran uses to disguise Iranian oil shipments to China through ship-to-ship (STS) transfers involving sanctioned vessels. On May 08, 2025, the United States imposed sanctions on the tanker IMO 9171448. According to IMO’s Global Integrated Shipping Information System (GISIS) data as of July 14, 2025, the vessel’s registered name is IMPALAS, flag unknown.[sources]
