A Notice of Inability to Ship (also known as Non-Delivery Notice) is a document issued by a shipping carrier or freight forwarder to a customer when they are unable to ship goods for any reason. This notice may be sent via email, mail, or fax and includes the following information: • Details of the shipment: carrier, origin and destination, date of shipment, and shipment reference number. • Reason for the inability to ship, such as lack of shipping space, delay in customs clearance, or other unforeseen issues. • Suggested plan of action, such as alternate delivery options or a new estimated delivery date. There are two types of Notice of Inability to Ship: Non-Delivery Notice and Reschedule Notice. A Non-Delivery Notice is issued when a shipment cannot be delivered due to an unforeseen issue, such as lack of shipping space or delay in customs clearance. A Rescheduling Notice is issued when a shipment is delayed due to an unforeseen event, such as weather or mechanical issues.
