How are electronic sensitive devices (ESD) identified on the item record?

Electronic Sensitive Devices (ESD) are identified on the item record using Type Cargo codes. The correct response indicates that ESDs are classified under Type Cargo code 3. This classification is essential for the tracking and management of these sensitive electronic items due to their susceptibility to damage from electrostatic discharge. Proper identification ensures that appropriate handling precautions are taken during storage and transportation, which is critical to maintaining the integrity and functionality of these devices.

In the context of the other options, IEX codes relate more to specific exceptions or conditions pertaining to the issuance or condition of a logistic item, while Type Cargo codes provide a broader categorization that includes sensitive electronic goods like ESDs. This distinction is vital in material management practices, as it helps streamline logistics operations and ensure that personnel recognizes the unique requirements for handling ESDs correctly.
