State property; creating a differential pricing preference for the cost of goods manufactured or produced in the United States of America. Effective date.

SB 168 requires Oklahoma state agencies to use iron, steel, and aluminum manufactured entirely in the U.S. for public construction projects (like roads, schools, or bridges) with contracts exceeding $100,000. Contractors must confirm they understand this requirement in their bids, and agencies must include it in all solicitation documents. Exceptions are allowed if materials aren’t available domestically, using U.S. materials would increase costs by over 25%, or it harms the public interest, with a formal appeal process involving public comment. The law applies to all state public works projects starting November 2025.
