This page reports that Iran collects transit fees of approximately one dollar per barrel of crude oil in yuan or cryptocurrency for passage through the Strait of Hormuz. Vessels are required to display "friendly nation" flags and use designated routes. Iran classifies countries into five categories with conditions varying by friendly status. Large tankers have a loading capacity of about two million barrels. Pakistan, mediating between the US and Iran, is permitted 20 transits. Transit requires providing ship and destination information to intermediaries connected to Iran's Revolutionary Guards. After review, toll negotiations begin, followed by permit codes and escort by Iranian patrol boats.
