Amidst the flurry of tariff threats swirling around the world, the Federal Highway Administration (FHWA) is terminating the waiver known as the Manufactured Products General Waiver from the Buy America requirements found in 23 U.S.C.A § 313. The Buy America regulation requires all federal-aid projects to use only steel, iron, and manufactured products that are produced in the United States. Since 1983, these requirements have been waived for manufactured products that were permanently incorporated into federal-aid projects by not requiring such products to be produced domestically, apart from predominantly iron or steel components of manufactured products. This waiver is being phased out in 23 C.F.R. 635.410, an amendment to the Buy America regulation which establishes new standards that will apply to manufactured products on federal-aid projects. The final rule was published in the Federal Register on January 14, 2025 (Vol. 90, No. 8, pp. 2932-58).

The new rule, 23 C.F.R. 635.410, defines “manufactured products” as “articles, materials, or supplies that have been processed into a specific form and shape, or combined with other articles, materials, or supplies to create a product with different properties than the individual articles, materials, or supplies.” A manufactured product does not include an article, material, or supply if it is “classified as an iron or steel product, an excluded material, or another product category as specified by law or in 2 C.F.R. part 184” or “mixtures of excluded materials delivered to a work site without final form for incorporation into a project.” However, “an article, material, or supply classified as a manufactured product may include components that are iron or steel products, excluded materials, or other product categories as specified by law or in 2 C.F.R. part 184.”

Manufactured products must be manufactured in the United States effective for federal-aid projects obligated on or after October 1, 2025. The Manufactured Products General Waiver will remain in place until then. The additional requirement to have greater than 55% of the manufactured product’s components, by cost, be mined, produced, or manufactured in the United States becomes effective for federal-aid projects obligated on or after October 1, 2026. For all federal-aid projects obligated on or after October 1, 2026, all manufactured products permanently incorporated into the project must both be manufactured in the United States and have the cost of the components of the manufactured product that are mined, produced, or manufactured in the United States be greater than 55% of the total cost of all components of the manufactured product.

Under the new rule, an article, material, or supply is generally only subject to one set of requirements. The classification of an article, material, or supply is made based on its status at the time it is brought to the work site for incorporation into an infrastructure project. The work site is the location of the infrastructure project at which the iron or steel product or manufactured product will be incorporated. The new rule also provides additional clarifications for precast concrete products and enclosures of electronic hardware systems classified as manufactured products, as well as, how to determine whether the cost of components for manufactured products is greater than 55% of the total cost of all components.
