Note
The U.S. Treasury / OFAC sanctioned 183 vessels in its 10 January 2025 action intensifying sanctions on Russia's oil production and exports, most of them oil tankers tied to the shadow fleet (143 tankers). A source-reported count for a single dated action, not a cumulative total and not real-time. An enforcement indicator; scope depends on official OFAC guidance. Not legal or compliance advice.
