When should the national item identification number (NIIN) be used in the CMRS search?

The national item identification number (NIIN) should be used in the CMRS (Customer Material Reporting System) search specifically when there are no matching records from a DODIC (Department of Defense Identification Code) search. The NIIN is a critical part of the logistics and inventory management system within the military, as it uniquely identifies items that may not necessarily be cataloged under a DODIC.

In cases where a DODIC search does not yield any results, utilizing the NIIN allows personnel to still locate the required material based on its unique identification number, ensuring that they can find the right item even if it doesn't have a corresponding DODIC record. This is particularly important for ensuring effective supply chain management and maintenance of operational readiness. By relying on NIINs, aircrews can access a more comprehensive database of items, thereby enhancing their ability to find and track equipment and supplies necessary for their missions.
