How can an over shipment best be described?

An over shipment can best be described as air inbound cargo that arrives but is not listed on the manifest. This situation occurs when additional cargo is delivered alongside the expected items, causing discrepancies between what was documented and what is received. It highlights the importance of accurate cargo management, as the presence of unmanifested items can lead to confusion and potential security concerns. Understanding the nuances of over shipments is essential for proper inventory control and accountability within air freight operations.

The other options do not accurately capture the definition of an over shipment. Excess cargo listed on the manifest refers to items that are accounted for, making it a different scenario. Mistakenly sent cargo suggests a misunderstanding or error in shipper instructions, while cargo that exceeds weight limits pertains to compliance issues rather than misrepresentation in documentation. Each of these scenarios, while related to air freight operations, has distinct definitions that do not align with the concept of over shipment as described.
