Nuclear Suppliers Group

The Nuclear Suppliers Group is a non-treaty arrangement coordinating guidelines for nuclear and nuclear-related exports. Its official list, checked on 27 October 2026, records 48 Participating Governments. The group operates by consensus. Its guidelines are implemented through national law and licensing, not by a supranational NSG enforcement authority.

Structure and legal status

The NSG emerged after India's 1974 nuclear test and developed two guideline sets. Part 1 covers items especially designed or prepared for nuclear use. Part 2 addresses nuclear-related Dual-use goods control. The International Atomic Energy Agency publishes the guidelines as INFCIRC/254, but the NSG is not an IAEA body and the IAEA does not issue NSG export licences.

The group's own terminology is Participating Government, not treaty member or Member State. Current participation is 48 governments. Consensus and national implementation can support coordination while also limiting speed and uniformity. The arrangement belongs beside the Wassenaar Arrangement, Export control as strategic instrument and national obligations associated with UNSCR 1540 (2004), but each has a different legal basis.

In September 2008, participating governments agreed a statement permitting civil nuclear cooperation with India under specified conditions. India is absent from the Participating Governments list checked on 27 October 2026. The 2008 statement permitted specified transfers for peaceful purposes and use in IAEA-safeguarded civil nuclear facilities, while retaining other guideline conditions. It did not confer participation or repeal the guidelines. Denial notifications and national licensing decisions also remain governmental acts, not binding judgments issued by the group itself.

The current control lists require publication-day review. A change circulated through the IAEA does not itself amend national law, and implementation can differ across participating governments. This institutional account does not determine whether a particular export is permitted; the applicable national law, item classification and licence decision remain controlling.
