When all the equipments of the document/MRN have arrived at the terminal, Portbase will report the arrival to Customs. Customs only sends a message back if the document is rejected or an inspection is announced. Portbase automatically releases the shipment after 5 minutes. An inspection can always be announced until the moment the ship departs. In addition, there are a number of document types that do not require an arrival notification to Customs, such as ICT and TT1. These are immediately set to automatic released.
