A new state law requires contractors and suppliers on public works projects to source all iron and steel exclusively from US manufacturers—with no phase-in period.
Most South Carolina manufacturers bidding on state and local public works projects don't yet realize how H4709 will reshape their sourcing decisions. The bill contains a mandate that goes into effect immediately upon the Governor's approval, with no transition window.
H4709 adds a new requirement to South Carolina's public procurement rules: any small business contractor or materials supplier bidding on state or local public works projects funded with state-appropriated money must source all permanently incorporated iron and steel products exclusively from US manufacturers.
The scope is comprehensive. It covers every step of production—from initial melting through coating application. If your company supplies or installs structural steel, reinforcing bar, fasteners, pipes, or any other iron or steel component that becomes a permanent part of the finished project, the material must originate from a US manufacturer.
If you're a contractor, fabricator, or materials supplier pursuing bids on publicly funded construction, renovation, or infrastructure work in South Carolina, this applies to you. The requirement attaches to any project using state-appropriated funds—meaning state budget dollars, not just federal money.
Even if you've never had trouble sourcing domestically, the law creates a contractual obligation. Failure to comply exposes your business to breach of contract claims, which can result in project termination, payment withholding, or legal liability.
Section 11-35-5350(B)(1) of the bill (found on page 1 under SECTION 1) establishes the rule. The effective date is upon approval by the Governor, as stated in SECTION 2. There is no phase-in period or grace window. Once signed, the requirement is active immediately for all new bids and contracts.
Review your current supplier relationships. If you source iron or steel from international suppliers or distributors who import materials, you'll need to identify domestic alternatives or confirm that your current suppliers already source from US manufacturers. This includes verifying the entire supply chain—not just the final seller, but where the material is actually melted and processed.
Update your bid templates and subcontractor agreements to reflect the requirement. Make sure anyone you work with on state-funded projects understands the mandate and can certify compliance.
If you're unsure whether a material qualifies as "permanently incorporated," or if you have questions about specific product categories, document your interpretation and consider consulting with your legal or compliance team before submitting bids.
The law is straightforward in its language but broad in its scope. Planning ahead will help you avoid costly compliance problems down the road.
