H.R. 3854, the Manufacturing Partnership Improvement Act, modifies the Hollings Manufacturing Extension Partnership program at the National Institute of Standards and Technology to strengthen support for American manufacturers. The bill requires that the program's Advisory Board include at least one member representing labor organizations involved in manufacturing or skilled trades apprenticeships, ensuring worker perspectives in the program's governance. Additionally, the legislation directs Manufacturing Extension Partnership centers to establish partnerships with regional offices of the Small Business Administration, Economic Development Administration, Department of Labor, and U.S. Export Assistance Centers to help small manufacturers and exporters access loans, federal assistance, workforce development programs, and export support services. The bill makes various technical corrections to existing law but does not specify new funding amounts or implementation timelines. Overall, the measure aims to improve how the federal government assists small and mid-sized manufacturers, particularly by connecting them to existing resources across multiple agencies.
