Which item is not checked when off-loading property from a carrier?

The item that is not checked when off-loading property from a carrier is the production date. When receiving goods, the primary focus is on the immediate conditions that pertain to the transfer process. These typically include ensuring that the item condition is satisfactory, confirming that the receiver’s signature is collected as proof of delivery, and verifying the carrier's details for accountability and traceability.

The production date of the items, while important for inventory management and quality control in the broader context of supply chain operations, does not directly affect the immediate process of off-loading and confirming receipt of the items from a carrier. Therefore, it does not need to be checked at this stage, allowing personnel to concentrate on the more pertinent aspects such as physical condition and documentation.
