When should the national item identification number (NIIN) be used on the conventional munitions restricted/suspended (CMRS) search screen?

The national item identification number (NIIN) is utilized on the conventional munitions restricted/suspended (CMRS) search screen primarily when a DOD identification code search does not yield any matching records. This approach ensures that if the direct search by DOD identification code fails, users can still obtain information about a specific item by using the NIIN, which uniquely identifies items within the DOD supply system.

The NIIN serves as a critical identifier, allowing personnel to access necessary details and statuses regarding munitions or equipment that may not be recognized by the initial DOD code. This practice enhances efficiency and ensures that all avenues for information retrieval are explored, especially in the context of maintaining operational readiness.
