Goods brought into the customs territory are covered by an entry summary declaration lodged by the carrier (or instead by the importer, consignee or others able to present the goods) at the office of first entry within the set time before arrival, containing the safety and security particulars (ICS2), amended only before customs signal an examination or find errors or goods are presented; it is invalidated if goods do not arrive (on request or after 200 days).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
