The Defense Logistics Agency (DLA) plans to issue an unrestricted Request for Proposal for two National Stock Numbers (NSNs) under a FAR Part 15 contracting by negotiation, with an anticipated indefinite quantity contract lasting up to five years (three base years plus two option years). The solicitation is expected to be available on or about June 15, 2026, and will remain open for 30 days for proposal submissions. Award decisions will consider price, past performance, and delivery, and the government does not possess complete technical data, so it intends to contract with approved sources listed for each NSN. No specific budget amount is provided, and the location for performance of services is not specified. Items are for DLA Direct (Stock) requirements, with inspection/acceptance and packaging details to be specified in the solicitation.
