All goods to be placed under a customs procedure (other than free zone) are covered by the appropriate customs declaration containing all necessary particulars, lodged by a person able to provide all the information and present the goods, established in the Union unless an exception applies; supporting documents are in the declarant's possession and available to customs when the declaration is lodged (or obtained through the EU Single Window for listed non-customs formalities).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
