The Treasury Department designated 17 vessels and their associated companies under Operation Economic Outcast, while the State Department sanctioned another five vessels, 10 entities and six individuals involved in trading Iranian petroleum and petrochemical products. Among the named vessels were the Cameroon-flagged tanker SHENZHEN, which Treasury said moved more than 3.5 million barrels of Iranian crude since November 2025, and the Vanuatu-flagged TINA 5, which allegedly carried more than 1.5 million barrels in August alone.
Treasury said the measures effectively neutralize the vast majority of Iran’s remaining shadow-fleet network, though maritime tracker TankerTrackers.com says 173 Iran-linked tankers remain outside US sanctions. Treasury also removed two vessels, HAKUNA MATATA and PINOCCHIO, from its sanctions list after they left Iran’s shadow fleet and were sold to operators not subject to sanctions.
