What will be used if an FSC is not assigned to a NICN?

When a Federal Supply Class (FSC) is not assigned to a National Item Control Number (NICN), the placeholder 0000 is utilized. This practice is essential because it indicates the absence of an FSC classification for that specific NICN, which allows for the maintenance and management of inventory in logistics systems without creating confusion about item classifications.

Using 0000 helps streamline operations by clearly identifying items that do not have a designated FSC, enabling logistics specialists to make informed decisions regarding inventory management, procurement, and supply chain strategies. The other options, though potentially relevant in different contexts, do not serve the specific purpose of indicating a missing FSC when dealing with NICNs.
