A new South Carolina law makes domestic sourcing mandatory for any contractor bidding on state or local public-works projects—and noncompliance carries real penalties.
Most South Carolina manufacturers don't realize that a provision buried in H4709 has already reshaped the rules for bidding on public-works contracts in the state. If you supply or install iron or steel for any state or local infrastructure project, this law affects you directly—and the stakes for getting it wrong are significant.
Effective upon the Governor's approval, Section 11-35-5350(B)(1) of H4709 mandates that all iron and steel used in South Carolina public-works projects must be produced in the United States. This isn't a preference or an incentive. It's a contractual requirement.
The law is specific about what "US-produced" means: every step of the manufacturing process—from initial melting through final coating—must occur within the United States. A product that is melted domestically but finished or coated abroad does not qualify. Neither does material that is imported in semi-finished form and completed here.
If your company bids on or supplies materials for any state agency, county, or municipal public-works project, you are bound by this requirement. This includes roads, bridges, water systems, public buildings, and similar infrastructure. General contractors, subcontractors, and materials suppliers all fall under the same obligation.
The requirement applies to every bid submitted after the Governor's approval. There is no sunset date stated in the law, meaning this is permanent unless the legislature changes it.
Failure to furnish US-produced iron and steel exposes your company to breach-of-contract liability. You can be disqualified from the bid, lose the contract, or face legal action from the contracting agency. For small businesses with tight margins, a breach-of-contract claim can be serious.
The risk extends beyond a single lost project. Disqualification from one public-works bid can affect your eligibility for future bids with that agency or others.
Review your current supply chain. If you source iron or steel from international suppliers or use imported materials in any stage of production, you'll need to identify domestic alternatives before bidding on public-works contracts. This may mean higher material costs, longer lead times, or different product specifications.
Confirm the sourcing documentation for any material you plan to use. Contractors and suppliers should require written certification from their material sources proving US production. Don't assume a supplier's claims without documentation.
If you work with subcontractors or material suppliers, communicate this requirement clearly in your bid documents and contracts. Make it their responsibility to certify compliance, and require proof before you submit a bid.
The law is straightforward, but enforcement depends on accurate sourcing information. Getting this wrong is expensive. Getting it right requires knowing your supply chain.
