At ASAP Semiconductor, we make sure that our clients' supply chain processes run smoothly. Our customers in the Aerospace, Aviation, Military and Defense industries can explore our wide range of National Stock Number parts through our proprietary website ASAP Aerospace.
To regulate the procurement process, the U.S. Department of Defense established a system that distinctively and permanently identifies the items that it purchases. This system, called the National Stock Number (NSN), is made of 13 digits which are broken down into the 2 ensuing identifying subcategories :
For example, an existing lapping tool we supply at ASAP Semiconductor has a 13-digit NSN of 5110-00-005-2375. The FSCG is represented by 5110, and the NIIN by 000052375.
Continuing on, the FSCG and NIIN can be broken down even further into the following classifying subcategories :
In the above lapping tool example, the FSG is represented by 51, and the FSC by 10.
National Codification Bureau - The first 2 digits of the NIIN identifies the National Codification Bureau (NCB) or NATO country code.
Item Serial Number- The last 7 digits of the NIIN is merely an item serial number that does not follow an assignment pattern.
In the above lapping tool example, the NCB is represented by 00 (USA).
