U.S. officials say that so far the blockade has turned back 34 ships, but ship-tracking data shows Iran has still been to move some of its sanctioned oil.

Lloyd's List Intelligence said "a steady flow of shadow fleet traffic" has passed in and out of the Persian Gulf, including 11 tankers with Iranian cargo that have left the Gulf of Oman outside the strait since April 13.

The maritime intelligence firm Windward said this week that Iranian traffic continues to flow "via deception."

Iranians are able to evade the blockade by faking tracking data and by traveling through Pakistani territorial waters.
