The item is subject to Free Trade Agreements and the World Trade Organization Government Procurement Agreement, highlighting its international significance. Interested vendors must submit the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, which is available online, and can direct inquiries to Samantha M.
