Post-shipment On-site Inspections of Military Materiel: Challenges and Responses

Post-shipment on-site inspections enable a state to perform checks on exported military materiel after they have been delivered. This SIPRI Policy Brief is intended to inform the various national processes currently underway that are connected to the adoption and implementation of on-site inspections as well as ongoing discussions within the Arms Trade Treaty about their role in helping to prevent diversion of military materiel.

The brief examines the concerns raised and challenges encountered by states in connection with adopting, requiring, and conducting on-site inspections and provides examples of practices that have been used in response. The brief also outlines how on-site inspections can be adopted and deployed in ways that help to promote cooperation between exporters and importers in preventing diversion of military materiel.
