This is a combined synopsis/solicitation for commercial items, with the government anticipating awarding a sole-source, firm-fixed price purchase order to Loos & Co, Inc. All parts must be new, have clear traceability to that OEM, and be accompanied by a Certificate of Conformance; no substitute or alternate parts will be considered. The requirement is restricted, and while all responsible sources may submit a quotation, the government believes Loos & Co, Inc. is the only known source capable of meeting the traceability requirements. The closing date and time for receipt of offers is 13 April 2026 at 09:00 am EDT. Quotes and questions must be submitted by email to the specified address.
