Heavy Duty Manufacturers Association--HDMA

The Heavy Duty Manufacturers Association (HDMA) was established in 1983 to meet heavy duty product manufacturers’ need for a national association dedicated to their specific interests. HDMA is the only organization in the heavy duty sector today dedicated exclusively to heavy duty manufacturers. Everything HDMA does - from market research to government representation - is driven solely by the best interests of manufacturers.
