Domestic Content for Treasury Notice 2025-08
IronRidge offers racking systems that use 100% domestically-produced components. Our products—made in the United States—include rails, structural fasteners, roof attachments, and the BX Ballasted System.
To meet the qualifying criteria for tax credit incentives, solar projects must use a combination of modules, inverters (MLPE or string), and racking with a minimum aggregate threshold of 45% Domestic Content.***
NO NEED TO SETTLE: Pick reputable products that your crews like installing. IronRidge offerings are listed to UL 2703 and UL 3741, tested rigorously, and manufactured to the highest quality standards.
DO YOUR HOMEWORK: Understand terms and definitions. Obtain letters from the manufacturer to share with your tax and legal counsel. Make sure they can also provide traceability in case of audit.
STACK MANUFACTURERS: IronRidge has partnerships with the leading inverter manufacturers. This allows our customers to have multiple avenues for them to reach the 45% domestic threshold.*
READ THE FINE PRINT: Only taxpayers offering third-party-owned systems and other commercial entities are eligible. Installation companies and homeowners do not directly qualify. Consult a tax professional.
BE FULLY PREPARED: Audits by financiers, commercial project owners, other taxpayers, and the IRS are serious business. Ensure manufacturing partners can help you navigate potential oversight.
STAY IN THE KNOW: The Bonus Credit is complex and nuanced. We provide resources pertinent to our customers. IronRidge does not give tax or legal advice – consult your own counsel.

***The “One Big Beautiful Bill” (OBBB) increased the adjusted cost percentage for the Investment Tax Credit (ITC) (domestic content bonus) to 45% for projects that begin construction after June 15, 2025, and before January 1, 2026. This increase aligns the domestic content adder rules for the ITC with the phased increases already applied to the Production Tax Credit (PTC). Please speak to your tax and legal counsel for guidance on the threshold for your project(s).
