The shipment reference number is a unique identifier assigned to a specific shipment of goods that are being imported or exported. The shipment reference number is typically created by the freight forwarder or the carrier (e.g., the shipping company) that is responsible for transporting the goods.

The format of the shipment reference number can vary depending on the specific carrier or freight forwarder. In general, it should be a unique alphanumeric code that is assigned to a particular shipment and is used to track and identify the shipment throughout the import or export process. The shipment reference number may include information such as the carrier’s code, the date of the shipment, and the origin and destination of the goods.

It is important to accurately record and track the shipment reference number in order to properly process the import or export of the goods and to ensure that the correct duties and taxes are assessed. The shipment reference number may be used by various parties involved in the import or export process, including CBP, the importer, the exporter, and any brokers or intermediaries.
