Membership Levels

Regular Membership

Established companies, with significant North American operations and sound financial condition, actually engaged in the manufacture, production, formulation, and/or remanufacture, of products for the OEM and aftermarket heavy duty commercial vehicle industry (i.e. products for class 4-8 commercial vehicles including trailers, and/or 50+ hp off-highway) shall be eligible for regular membership in the association when approved by the Board of Governors.

Council Membership

Councils and forums are a highly valued asset among our members.  Only HDMA members are eligible to join and participate, with each round-table group focusing on a different market segment or business function.

HDMA Forums are self-governed under the guidance of HDMA and meet twice a year.  They are geared towards key executives in an organization.  Forums offer peer-to-peer networking among an elected group of supplier executives, while discussing industry trends and developments.

HDMA Councils are self-governed, action-oriented groups.  Their projects include conducting research and surveys that often extend to all HDMA members once full developed.  HDMA Councils also focus on the monitoring of key trends, topics, and issues that are most relevant to suppliers' businesses.
