Conference of State Manufacturers Associations
Work with a network of state-based manufacturing organizations to advance smart policies at the local level.
Conference of State Manufacturers Associations
Uniting manufacturers across the borders of our states
The Conference of State Manufacturers Associations is a powerful network of 50 state manufacturers’ associations representing more than 59,000 companies that work together to advocate for and solve the industry’s biggest challenges. With a focus on advocacy, leadership and operational excellence, COSMA and the NAM provide state associations access to resources, leading insights, strategic allies and the thought leaders shaping the future of manufacturing — through the Power of Us.

Partnerships that produce
Where COSMA members drove results in 2025
Working with the NAM, COSMA members magnified manufacturers' priorities in Washington and in every state capital — sharing intel, pooling resources and speaking with a unified voice.
Winning on Tax Reform
68% of COSMA members joined more than 300 manufacturing organizations in support of the One Big Beautiful Bill Act (H.R. 1) — securing the tax trifecta, the TCJA international system and new incentives for manufacturing investment. Six members released jointly branded print ads with the NAM in major state dailies.
Sensible Regulations
78% of COSMA members signed the Manufacturers for Sensible Regulations roadmap to the incoming administration — three dozen regulatory actions, from PFAS and overtime rules to broadband and energy security, to boost manufacturing growth from day one.
Navigating Trade
COSMA CEOs convened on tariff implications with state-by-state trade data and district breakouts, circulated the NAM tariff survey to manufacturers in their states and pressed for zero-for-zero tariff deals and predictable access to critical inputs.
Workforce Solutions
COSMA’s Workforce Peer Group, the MI Workforce Summit (300+ organizations) and a network of MFG Day bus tours, Coolest Thing Made competitions and frontline training programs are building the manufacturing workforce of the future, state by state.
Strengthening the MEP Network
When Manufacturing Extension Partnership funding came under pressure, COSMA organizations representing 68% of states sent a joint message to the commerce secretary and every member of Congress urging a restructured, manufacturer-focused MEP network.
Partnerships in the Courts
COSMA members and the NAM Legal Center joined forces in courtrooms nationwide — a permanent injunction preserving corporate free speech in Minnesota v. Choi, briefs in Illinois against forum shopping and support for a water-quality challenge in Washington state.
