The Arms Trade Treaty Hub

The Arms Trade Treaty (ATT), the first global, legally binding instrument to regulate the transfer of conventional arms, was adopted by the United Nations (UN) General Assembly on 2 April 2013. It entered into force on 24 December 2014 and, as of 2025, has 118 states parties and 25 signatories. The treaty is intended to require government regulation of transfers of military hardware, thereby reducing risks of diversion while promoting transparency and accountability in the legal arms trade.

The Small Arms Survey works to support the effective implementation of the ATT by providing relevant data and evidence-based policy support and guidance to diplomats, policymakers, researchers, civil society actors, and other stakeholders.
