Resolution 2231 (2015) endorsed the establishment by the JCPOA of a dedicated “procurement channel” for the transfer of items, materials, equipment, goods and technology required for Iran’s nuclear activities under the JCPOA.

The Security Council requested that the Director General of the IAEA submits to the IAEA Board of Governors and in parallel to the Security Council:

In accordance with paragraph 6.10 of Annex IV of the JCPOA, the Joint Commission reports to the Security Council at least every six months on the status of the Procurement Working Group’s decisions and on any implementation issues.

As requested by the Security Council, the Secretary-General will report to the Council every six months on the implementation of resolution 2231 (2015).

Annex B of resolution 2231 (2015) also requires all States to take the following actions:

Pursuant to paragraph 6 (f) of Annex B of resolution 2231 (2015), all States are to take the required actions, in accordance with the resolution and guidance provided by the Security Council, with respect to items the supply, sale, transfer, or export of which is being undertaken contrary to the provisions contained in the JCPOA or this statement, and cooperate in such efforts.

The restrictive measures contained in paragraph 6 (c), (d) and (e) of Annex B to resolution 2231 (2015) applied until the date five and eight years after Adoption Day of the JCPOA (18 October 2015). 
Consequently, the 2231 List has been removed from the Security Council website and corresponding changes were made to the United Nations Security Council Consolidated List.
