For what type of shipment is the requisition identified by NSN/NATO stock number used?

The requisition identified by the National Stock Number (NSN) or NATO Stock Number is primarily used for domestic shipments. This numbering system is essential for standardizing inventory and supply chain management within the U.S. military and its allied partners. The NSN is a unique identifier assigned to items that are recognized in the supply system, ensuring that they can be accurately ordered, tracked, and managed, primarily within the national supply framework.

While the NSN is also used in international contexts, the question specifically asks about the type for which a requisition with this identifier is used, highlighting the strong relationship of NSN with domestic operations. In this respect, most requisitions that are processed using the NSN are conducted within the confines of the domestic military logistics system, as this standardized approach facilitates consistent supply procedures and inventory control across various branches of the military within the country.
