A packing list is a detailed document that accompanies a shipment, listing all items included in the package or container. It serves as a reference for both the sender and receiver, helping ensure that all goods are accounted for upon arrival. The packing list typically includes information such as item descriptions, quantities, weight, dimensions, and sometimes the value of the goods. In shipping, a packing list is essential for customs clearance, inventory management, and verifying that the correct products have been shipped. It helps streamline the receiving process, reducing the chances of errors or discrepancies.
