logistics staff, carrier, and consignee should control missing-unit investigation as a separate item for the Tanzania project. Each approval of missing-unit investigation should cite the same voyage, VIN, time, and handover point for traceability. Record the date and version of the arrival manifest, gate records, discharge photos, and claim charge evidence, and cross-check them vehicle by vehicle against the discharge time. If missing units on arrival, damage, or a charge dispute is found, open an exception first and pause the affected handover until responsibility is established. For a practical way to organize order evidence, see this vehicle-import FAQ. When missing-unit investigation is handed over in Tanzania, retain the prior decision and the reason for the revision. Declaration and investigation of missing units on arrival in the destination country follow local-authority rules, licensed-body requirements, and the applicable contract terms. If the Tanzania team needs a delivery checklist, state missing-unit investigation and the planned timing on WhatsApp.
