This legislation amends the Infrastructure Investment and Jobs Act to expand the scope of the Build America, Buy America Act by including specific yellow organic pigments as "construction materials." The primary goal is to ensure that these pigments, crucial for road, highway, and airport surface markings, are domestically sourced, thereby supporting American industry. This change aims to bolster domestic manufacturing capabilities for these essential infrastructure components. The inclusion of these pigments is implemented in two phases: initially, all yellow organic pigments in water-based paints for surface markings are considered construction materials upon enactment. Two years later, this requirement extends to all formulas for such markings, ensuring comprehensive domestic sourcing. The bill also provides a precise definition for when a yellow organic pigment is considered "produced in the United States," requiring all manufacturing processes, including chemical reactions, to occur domestically, from initial combination of materials through the synthesized pigment. To facilitate this change, the Director of the Office of Management and Budget is mandated to update relevant guidance, including that of the Made in America Office, within 90 days of the bill's enactment. This ensures a timely and consistent application of the new domestic content requirements across relevant federal programs, reinforcing the commitment to American-made products in infrastructure projects.
