If any essential change is made to the details and/or conditions of the consented shipment, including changes in the intended quantity, route, routing, date of shipment or carrier, the notifier shall inform the competent authorities concerned and the consignee immediately and, where possible, before the shipment starts.

In such cases a new notification shall be submitted, unless all the competent authorities concerned consider that the proposed changes do not require a new notification.

Where such changes involve competent authorities other than those concerned in the original notification, a new notification shall be submitted.
