The Trump administration has formally issued a waiver on the sale on Iranian oil, following through on a promise from the Memorandum of Understanding signed by President Donald Trump.
The waiver legalizes the sale of Iranian oil and allows transactions involving vessels that had been previously sanctioned.
The sanctions will be waived for a 60-day period beginning Monday and ending at 12:01 a.m. ET on Aug. 21.
The waiver also allows for "any payment of funds owed to Iran, the Government of Iran, or any blocked person for the purchase of crude oil" to be made in U.S. dollars.
The waiver does not, however, allow the sanctions on Iranian oil to be lifted for people in North Korea, Cuba and parts of Ukraine like Crimea.

The technical talks follow Sunday's discussions between high-level U.S. and Iranian delegations. Those talks ended early on Monday, Pakistani Prime Minister Shebhaz Sharif said.
Baqaei told IRNA that Kazem Gharibabadi, Iran's deputy foreign minister for legal and international affairs, is leading the Iranian delegation in the technical negotiations.
According to a joint statement issued by the mediators, the technical working groups will focus on nuclear issues, sanctions, monitoring mechanisms and dispute-resolution procedures, with negotiations set to continue in Switzerland through the end of the week.
