BABA basics for infrastructure projects
A plain-language briefing on Build America, Buy America — iron and steel, manufactured products, construction materials, the 55 percent component test, and how it differs from older Buy America rules.
September 9, 2026
Build America, Buy America (BABA) is the infrastructure domestic-preference rule in the Infrastructure Investment and Jobs Act. It tells federal agencies that, subject to the statute and 2 CFR Part 184, none of the funds made available for a federal award for an infrastructure project may be obligated unless the iron, steel, manufactured products, and construction materials incorporated into that project are produced in the United States.
That sentence is doing a lot of work. This article unpacks the categories, the manufactured-product percent, and how BABA sits next to older Buy America statutes. It is educational, not a coverage opinion. Use the applicability check for a funding-type sketch, then read the award.
What “produced in the United States” means
2 CFR 184 defines the test by product class:
- Iron or steel products. All manufacturing processes, from the initial melting stage through the application of coatings, occurred in the United States.
- Manufactured products. The product was manufactured in the United States and the cost of components that are mined, produced, or manufactured in the United States is greater than 55 percent of the total cost of all components, unless another law sets a higher standard for that award. Component cost is described in 2 CFR 184.5.
- Construction materials. All manufacturing processes for the material occurred in the United States. The regulation lists materials such as non-ferrous metals, plastic and polymer-based products, glass, fiber optic cable, lumber, and drywall, and it points to 2 CFR 184.6 for process detail.
Cement, cementitious materials, aggregates, and aggregate binding agents are treated as section 70917(c) materials and sit outside the construction-material preference unless another program says otherwise.
The domestic content threshold helper runs the 55 percent “greater than” arithmetic and the all-processes screens. It also lets you compare 65 percent and 75 percent figures that appear in the Buy American Act (direct federal procurement under the FAR). Those percentages are a different statute. Do not drop a FAR number onto a BABA award unless the award itself does.
Infrastructure, not every federal purchase
BABA attaches to federal financial assistance for infrastructure projects in the United States — grants, loans, and similar awards — including when infrastructure is not the primary purpose of the award. Direct agency procurement of a laptop for a federal office is a different regime (often the Buy American Act). A purely private warehouse with no federal dollar is generally outside BABA. State-only funds are generally outside federal BABA, though states often have their own preference laws.
“Infrastructure” in the statute is broad: roads, bridges, public buildings, water, electrical transmission, broadband, and similar structures and equipment. The clean question for a desk is: is this item being incorporated into a federally assisted infrastructure project? If yes, start with BABA and then check the modal overlay.
BABA and the older DOT rules
BABA did not repeal FHWA, FTA, or FAA domestic-preference statutes. A federal-aid highway project can still be an FHWA Buy America project. Transit awards still carry 49 U.S.C. 5323(j). Airports still have Buy American on AIP work. IIJA dollars can layer BABA’s construction-material coverage onto programs that historically focused on steel and manufactured products.
FHWA has also been moving manufactured products off a long-standing general waiver and onto a phased domestic standard. Letting date and the current FHWA rule matter as much as the BABA baseline. The applicability tool flags that; it does not date your letting.
Waivers still exist
Agencies may waive BABA on the grounds the statute allows — public interest, nonavailability, unreasonable cost — through the Made in America process. A proposed waiver is a chance for a domestic producer to show supply. See how Buy America waivers work and how a waiver desk helps suppliers.
What public buyers and suppliers should actually do
Buyers: put the preference in the bid documents, flow it to subcontractors, and classify products before the shop drawing fight. Suppliers: know whether you are selling iron/steel, a construction material, or a manufactured product, and keep component-cost records if you are in the 55 percent world. Both sides should watch official waiver listings instead of assuming the domestic market is silent.
