"The waiver ensures that Iraq is able to meet its short-term energy needs while it takes steps to reduce its dependence on Iranian energy imports," a State Department spokesman said.
This will be the fifth such waiver the US has issued for Iraq to import energy from the Islamic Republic of Iran.
Trump re-imposed unilateral sanctions on Iran's energy and finance sectors in November last year following his decision to withdraw from a landmark 2015 nuclear deal signed between Tehran and six major world powers.
Iraq is heavily dependent on importing gas and electricity from Iran.
