End-user certificate

An End-user certificate, or EUC, is a document used in international transfers, including sales and arms provided as aid, 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 undesired destinations, such as embargoed states or rebel groups. Illegal, international arms dealers will resort to smuggling arms in crates of other commercial merchandise in order to avoid the paperwork of EUC's.
