This nuclear deal was endorsed by UN Security Council Resolution 2231, adopted on July 20, 2015.
Iran’s compliance with the nuclear-related provisions of the JCPOA is verified by the International Atomic Energy Agency (IAEA) according to certain requirements set forth in the agreement.
The following is a summary of the timeline, key components, and the current status of the multi-year agreement.
Timeline for Implementation
July 14, 2015, Finalization Day: conclusion of the agreement. Finalization day triggers Iran and the United States to begin domestic review processes of the JCPOA. Iran also begins providing the IAEA with information necessary for the agency to complete its investigation into past activities related to nuclear weapons development.
October 18, 2015, Adoption Day: 90 days after the passage of the UN Security Council Resolution endorsing the deal (July 20, 2015). Adoption day triggers Iran and the P5+1 to take steps (outlined below) to meet the commitments to fully implement the JCPOA.
January 16, 2016, Implementation Day: the IAEA certifies that Iran has taken the key steps to restrict its nuclear program and has put in place increased monitoring. The IAEA's report on implementation day triggers U.S., EU, and UN sanctions relief.
October 2023, Transition Day: Eight years after adoption day (or the IAEA reaching its broader conclusion on Iran's nuclear program, whichever is sooner). Transition day triggers the UN to lift missile restrictions, Iran to seek ratification of its additional protocol, the EU to terminate all remaining nuclear sanctions, United States to remove certain entities from the sanctioned list, and the United States to seek legislative termination of certain sanctions.
October 2025, Termination Day: Ten years after adoption day. Termination day terminates Resolution 2231 and the Security Council closes Iran's nuclear file.
