End-user certificate

An End-user certificate, or EUC, is a document used in international sales of weapons and ammunition to certify that the buyer is the final recipient of the materials, and is not planning on transferring the materials to another party. EUCs are required by many governments to restrict the flow of the materials to embargoed states. Illegal, international arms dealers will resort to smuggling arms in crates of other commercial merchandise in order to avoid the paperwork of EUC's.
