In the 26 days between the signing of the U.S.-Iran memorandum of understanding and the reinstatement of the U.S. blockade, Tehran shipped over $6 billion worth of oil products to foreign buyers.

Iran shipped out over 80 million barrels of crude oil and refined products between June 18, when the first blockade was lifted, and when it was reimposed on July 13, according to TankerTrackers.com, a tanker-tracking research firm. The blockade, however, closed around Iran before Tehran was able to ship out all of its storage capacity, so around 30 million barrels of Iranian crude oil were unable to embark.
