Release Notification System (RNS)

(Canada Customs) RNS is a Canada Border Services Agency (CBSA) import shipment program that includes four features: automatic release notification, arrival certification, status query and automatic status.
For Canadian importers authorized to use the automatic release notification feature of RNS, data confirming release of goods is electronically transmitted in the United Nations Electronic Data Interchange for Administration, Commerce and Transportation (UNEDIFACT) message format to their EDI mailbox using a third-party EDI network, also known as a value-added network (VAN), through the Customs Internet Gateway or through CADEX telecommunication lines. The RNS message can be used to update systems to schedule deliveries or initiate the preparation of accounting data, as well as to electronically notify other parties affected by the release and ensure more timely delivery of shipments.
For importers approved to use arrival certification, two-way electronic communication can be established to notify CBSA of the arrival of commercial shipments. Importers can also verify if CBSA has processed release documents for a shipment using the status query feature or by receiving an automatic status message. For importers who choose to transmit an arrival certification message, CBSA can advise whether the goods have been released or referred for examination. For more information, go to:
