text: The Trump administration imposed sanctions on two UAE based aviation companies, Parthia Cargo and Delta Parts Supply, that violated U.S. sanctions on Iran's Mahan Air by providing them logistics services and supplying parts to the Iranian airline. Federal prosecutors also filed criminal charges against one of the companies under violation of United States export control regulations.
  Countering America's Adversaries Through Sanctions Act
  The Countering America's Adversaries Through Sanctions Act (CAATSA) was enacted in August 2017 and imposed sanctions against Iran, as well as against Russia and North Korea. CAATSA requires the President to impose sanctions against: (1) Iran's ballistic missile or weapons of mass destruction programs, (2) the sale or transfer to Iran of military equipment or the provision of related technical or financial assistance, and (3) Iran's Islamic Revolutionary Guard Corps and affiliated foreign persons. The President may also impose sanctions against persons responsible for violations of internationally recognized human rights committed against individuals in Iran, and can waive the imposition or continuation of sanctions.
  Post-JCPOA sanctions
  In May 2018, the United States President Donald Trump announced an intention to withdraw from the Joint Comprehensive Plan of Action (JCPOA or Iran nuclear deal), and subsequently imposed several new non-nuclear sanctions against Iran,  some of which were condemned by Iran as a violation of the deal.
