NATO Stock Number (NSN)
The Nato Supply Number (13 digits) consists of material group, material class, country code, and NIIN (National Item Identification Number).
Federal Supply Class (FSC)
Federal Supply Class (FSC) codes are used to group products into logical families for management purposes. The four-digit fields, (defined within Cataloging Handbook H2-1) are used to

that do not fall under a FSC.
