The bill amends RCW 39.04.010, adds new sections to chapter 39.04 RCW, and creates a new section to require that iron, steel, aluminum, and manufactured products used in public building or other public works contracts that receive more than $500,000 of state funds in a capital budget or are financed through a financing contract under RCW 39.94.020 be manufactured in the United States, unless a specific waiver applies. It adds definitions of terms such as "manufactured in the United States" (for iron and steel, all manufacturing processes from initial melting through coatings occur in the U.S.; for manufactured products, more than 55% of component cost must be U.S.-sourced unless another law sets an equal or higher standard) and other procurement terms used in chapter 39.04 RCW. The bill creates procedural requirements and exceptions rather than a new criminal offense. It authorizes waivers by the Office of Financial Management director for state projects, a school district superintendent for school projects, or the executive head of a municipality for municipal projects if one of three conditions is met (public interest, insufficient domestic supply or quality, or a domestic requirement would increase cost by more than 25%). Waivers require at least 30 days of public notice and comment on the agency website and publication of a detailed justification addressing comments before the waiver takes effect. Contracts must include a provision rendering parties found by a court or federal/state agency to have intentionally misrepresented an ineligible product as "Made in America" ineligible to bid or enter contracts pursuant to debarment provisions; disputes under the new section must be arbitrated by the director of the Department of Labor and Industries, whose decision is final and binding. The bill names affected agencies (Office of Financial Management, school districts, municipalities, Department of Labor and Industries, various state agencies listed in RCW 39.04.010, and the Office of Minority and Women's Business Enterprises for small business certification references) and specifies that the domestic-manufacture requirement applies to projects advertised for bids after the section's effective date. The extract does not state the specific effective date, does not identify the precise "title" referenced for debarment provisions, and omits the full text of other cited RCW provisions and the referenced CFR provisions that are necessary for complete interpretation.

If enacted, the law would require most state-funded public construction projects over $500,000 (or financed under the cited financing contract authority) to use U.S.-manufactured iron, steel, aluminum, and manufactured products meeting a 55% domestic component-cost test for manufactured products, unless a formal waiver is granted. Waivers can be granted by the Office of Financial Management for state projects, school superintendents for school projects, or municipal executives for municipal projects, but only for limited reasons (public interest, insufficient domestic supply/quality, or if domestic sourcing raises the project cost by more than 25%), and each waiver must be posted for at least 30 days for public comment with a published justification before it takes effect. Disputes under this section go to final, binding arbitration by the Department of Labor and Industries director, and parties who intentionally mislabel foreign products as "Made in America" can be ruled ineligible for contracts through debarment provisions. The practical effects will fall most heavily on state agencies, school districts, municipalities, contractors and suppliers: they will face tighter sourcing rules, potential higher material costs, and added administrative work to seek or justify waivers and to comply with notice and documentation requirements. Contractors also face increased reputational and business risk from debarment if they misrepresent product origin, and agencies must ensure adopted rules meet any federal conditions for receiving federal funds. The bill text leaves important implementation details unclear here, including the effective date and the specific debarment procedure referenced, as well as how related RCW and federal standards will be applied in practice.
