The U.S. Department of Defense created the National Stock Number system in order to create a uniform naming system for all the components that are sourced, stocked, and procured within the federal supply system. NSNs are 13 digit serial numbers that classify and describe an item. Within the NSN are the smaller classification numbers, Federal Supply Group, Federal Supply Class, country code, and National Item Identification Number. Typically in the format, XXXX-XX-XXXXXXX, the first two digits of the NSN are the Federal Supply Group. The following two digits are the Federal Supply Class. The FSG and the FSC can be referenced in the Department of Defense’s H2 handbook

A typical tire will last for 10-200 landings before they are retreaded (rather than replaced). The tire itself will not be replaced until the core is worn out since a single tire replacement on a commercial jumbo jet runs around $90,000. Some examples of equipment in federal supply class 2640: tread gum, cold patches, friction cord fabric, vulcanizing patches, padding stock, tire and tube repair kits, valves, and valve cores.
