This is a sole-source procurement for 6 units of a specific NSN item, as the government lacks sufficient technical data to contract with any party other than the current source. The item is subject to Free Trade Agreements and WTO Government Procurement Agreement rules. Because these items require Government Source Approval prior to award, any offeror not already approved must submit the data required by the NAVSUP WSS Source Approval Brochure along with their proposal; otherwise, their offer will not be considered. Delivery is FOB origin. For questions, contact the listed government email.
