NCTS Phase 5: A Technical Walkthrough of the IE Message Flow

Departure IE015 — the declaration payload: consignment, house consignments, goods items, itinerary, guarantee, optional safety and security. IE028 — allocation of the Movement Reference Number. IE029 — release for transit and generation of the Transit Accompanying Document with an MRN barcode. IE051 — office of departure declines the movement. IE055 — guarantee refused. IE056 — functional errors with field pointers. Transit IE060 — control decision when customs elects to inspect. Electronic office of incident messages when disruption occurs. Arrival and discharge IE007 — arrival notification from the consignee. IE043 — permission to unload granted. IE044 — unloading remarks confirming the goods match the declaration. IE045 — write-off, releasing the guarantee reserve. The full sequence with rejection branches is documented in the iCustoms NCTS 5 IE015 to IE045 flow. What your integration must handle Idempotent MRN handling on IE028, error-code mapping for IE056, retry policy for IE051 and IE055, and clean state transitions between transit and arrival. Design your integration once, then keep it out of the border. Watch a demo.
