The Machinery Dealers National Association (MDNA) is an international, nonprofit trade association dedicated to the promotion of the used machinery industry. It was established in 1941 to assure buyers of the integrity and reliability of hundreds of used machinery dealers from around the world that are members of our association. The foundation of the MDNA is our Code of Ethics. As a condition of membership, MDNA members agree to abide, unequivocally, by the terms of the Code, and renew this pledge annually. MDNA member dealers offer trust, integrity, and the most extensive selection of used machinery in the world. We encourage you to explore our Web Site www.mdna.org and take advantage of the benefits of buying from an MDNA dealer.
