The Government intends a sole-source contract under FAR 6.302-1 for NSN 1H-6150-016628125, reference 7402174-4, quantity 10 EA, delivered FOB origin. The item must be acquired from or repaired by a source specified on source-control or selected-item drawings because suitable technical data, Government data rights, and manufacturing/repair knowledge are not available for other sources or testing. The notice is not a request for competitive proposals, but responsible sources may identify interest and capability or submit proposals, quotations, or capability statements, with any decision not to compete left to Government discretion. The acquisition will not use FAR Part 12 commercial-item policies, though interested parties may identify commercial-item interest and capability to the contracting officer. The acquisition may be subject to Free Trade Agreements and the WTO Government Procurement Agreement if the referenced DFARS clauses are included.
