The Machinery Dealers National Association (MDNA) has a distinguished history as a leader in the
metalworking industry for 55 years. This international, nonprofit trade association, was
established in 1941 to assure buyers of the integrity and reliability of used machinery dealers
who are members of MDNA. Today, the association represents more than 450 member firms with 1,000
executives throughout the world.
The foundation of MDNA is its Code of Ethics. As a condition of membership, MDNA dealers agree to
abide, unequivocally, by the terms of the Code and renew this pledge annually. The Code of Ethics
was written by member machinery dealers and is policed by the association's membership.
Complaints brought from Code violations are dealt with by the Ethics & Mediation Committee and
severe violations have resulted in expulsion from MDNA.
As an association MDNA has built an international profile for its membership, affiliates and
subsidiaries. The members of its affiliate, the Association of Machinery and Equipment Appraisers
(AMEA), are individual machinery and equipment appraisal professionals who have demonstrated their
proficiency through testing and peer review. AMEA's function is to accredit and certify its
metalworking machinery appraiser members through continuing education and written testing
procedures, and develop standards for the industry.
MDNA is also the publisher of the Serial Number Reference Book for Metalworking Machinery. The
purchase of this reference text and its continued publication by MDNA demonstrates the
association's dedication to serving the needs of the industry at-large. This text, which gives
year of manufacture and more, is a must for anyone working in maintaining, specifying, buying,
selling or appraising metalworking machinery and related equipment.
Machinery Information Systems, Inc. (MIS), publisher of LOCATOR® of Used Machinery,
Equipment & Plant Services for 26 years, is another of MDNA's subsidiaries. MIS also operates
the SuperFAXMate® network.
MDNA is comprised of 14 chapters, 12 in the United States and one in both Canada and Europe. In
addition to its industry-wide activities and chapter programs, the association also supports the
ideal of higher education for the children of member firm employees through the MDNA Austin D.
