FHWA final rule rescinds Manufactured Products General Waiver and phases in manufactured-products domestic content requirements

FHWA issued a final rule updating its Buy America requirements for Federal-aid highway projects by terminating the long-standing Manufactured Products General Waiver and establishing phased-in compliance criteria for manufactured products. Per the rule/agency announcement, projects with FHWA funds obligated on/after 2025-10-01 require U.S. final assembly/manufacturing for manufactured products, and projects obligated on/after 2026-10-01 additionally require that more than 55% of the cost of components be domestically produced. Compliance teams supporting highway infrastructure supply chains should update sourcing/BoM cost roll-ups and supplier certifications to meet the phased obligation-date thresholds.
