This paper describes one logistical technique referred to by MKS as the “Controlled Delivery” model (or Direct Factory Shipment Program, DFSP) for reducing the systemic risk of sensitive dual-use technologies being diverted to proliferation programmes of concern through illicit trade. The adoption of this voluntary approach by MKS is an example of “Anti-proliferation” in practice – the concept of resilience to proliferation in companies’ supply chains.
