This is a sole-source procurement for 28 units of a specific hose pump (NSN 6X-4730-LWM045971) from Cometto SPA, requiring engineering source approval to maintain part quality. Delivery is FOB origin, and the part’s unique design and manufacturing knowledge are held exclusively by the approved source, with data rights not economically available to the government. Alternate sources must qualify through government-approved procedures, but the government intends to negotiate only with Cometto SPA. Interested parties may submit quotes or capability statements, which will be considered before award, though the government retains discretion not to compete. No budget amount or performance location is specified.
