BABA Compliance for Industrial Enclosure Cooling
Build America, Buy America Act requirements for federally-funded infrastructure projects — and how VoltAire helps you stay compliant from spec to install.
Quick Summary
The Build America, Buy America Act (BABA) is a federal law that requires all iron, steel, manufactured products, and construction materials used in federally-funded infrastructure projects to be produced in the United States. It took effect on May 14, 2022, and applies to every federal financial assistance award for infrastructure obligated after that date — broadband, water, transportation, public buildings, and more. For enclosure cooling, this means your air conditioners and heat exchangers must satisfy the 55% U.S. component cost threshold and undergo final assembly in the United States. VoltAire enclosure air conditioners and heat exchangers are manufactured in Orlando, Florida and meet BABA requirements. We issue signed compliance letters on request, typically within one to two business days, so your project stays on schedule and your federal funding stays intact.
The Law
What Is the Build America, Buy America Act?
The Build America, Buy America Act — commonly abbreviated as BABA — was signed into law in November 2021 as part of the Infrastructure Investment and Jobs Act, the largest federal infrastructure package in a generation. Its core requirement is straightforward: when federal money pays for an infrastructure project, the iron, steel, manufactured products, and construction materials used in that project must be produced in the United States.
BABA took effect on May 14, 2022, and applies to every federal financial assistance award for infrastructure obligated on or after that date. It builds on the Buy American Act of 1933 but is much broader and significantly stricter. Where the original Buy American Act covered only direct federal procurement — the government buying things for its own use — BABA covers the much larger universe of federal grants, loans, and cooperative agreements that fund state, local, tribal, and private infrastructure projects.
The practical effect of BABA has been transformative. Tens of billions of dollars that flow from federal agencies to state DOTs, municipal water utilities, rural electric cooperatives, broadband providers, port authorities, and public school districts now carry BABA strings. Every fan motor, every contactor, every length of conduit, and every air conditioner installed under those projects must meet the new standards or qualify for a waiver.
The three product categories under BABA each have their own rule:
- Iron and steel products must be 100% manufactured in the United States. All manufacturing processes, from initial melting through application of coatings, must take place in the U.S. There is no domestic-content percentage for iron and steel — it is all or nothing.
- Manufactured products — the category that includes enclosure air conditioners, heat exchangers, control panels, and most electrical equipment — must be manufactured in the United States, and the cost of the components manufactured in the U.S. must exceed 55% of the total cost of all components in the product. The product must also undergo final assembly in the U.S.
- Construction materials such as non-ferrous metals, plastic and polymer-based products, glass, lumber, drywall, and engineered wood must be 100% manufactured in the United States. Each material has its own definition of what manufacturing steps must occur domestically, published by the Office of Management and Budget.
Each federal funding agency is responsible for implementing BABA on its own programs, which means the specific certification format, submittal timing, and inspection process can vary slightly from agency to agency. The underlying domestic-content thresholds, however, are uniform across the federal government.
Applicability
Does BABA Apply to Your Project?
Walk through this five-question checklist. If you answer “yes” to the first four and “no” to the fifth, BABA almost certainly applies.
Is your project receiving any federal financial assistance?
Federal grants, loans, loan guarantees, cooperative agreements, and certain federal-state matching funds all trigger BABA requirements. This includes pass-through funding from federal agencies to state DOTs, municipal utilities, port authorities, and rural electric cooperatives.
Was the project obligated after May 14, 2022?
BABA requirements apply to federal financial assistance obligations made on or after May 14, 2022. Projects funded earlier may fall under prior Buy American provisions instead. Check your award documents for the obligation date.
Does the project qualify as "infrastructure" under BABA?
BABA defines infrastructure broadly: roads, bridges, ports, airports, water and wastewater systems, broadband, electrical transmission, public buildings, dams, and many more. If the project produces lasting public benefit through physical assets, it likely qualifies.
Does your scope include manufactured products like cooling equipment?
Enclosure air conditioners, heat exchangers, control panels, and related electrical equipment are classified as "manufactured products" under BABA. The 55% domestic content rule applies plus final assembly in the United States.
Has your federal funding agency issued a project-specific waiver?
Some agencies grant categorical, public-interest, or non-availability waivers. Always verify in writing before assuming an exception applies. Most enclosure cooling installations do not qualify for waivers because BABA-compliant options are commercially available.
Common federal infrastructure programs that trigger BABA
- • BEAD broadband ($42.5B program)
- • EPA Drinking Water State Revolving Fund
- • EPA Clean Water State Revolving Fund
- • FHWA highway formula and discretionary grants
- • FTA transit capital grants
- • FRA rail infrastructure grants
- • USDA Rural Utilities Service loans
- • DOE grid resilience and modernization
- • FAA Airport Improvement Program
- • HUD Community Development Block Grants
- • Army Corps civil works projects
- • DOD military construction
Why It Matters
Why BABA Matters for Industrial Enclosure Cooling
Enclosure air conditioners and heat exchangers might seem like a small line item next to the bridges, fiber networks, and treatment plants that capture the headlines. In practice, they are everywhere on a federal infrastructure project, and they are nearly always classified as manufactured products under BABA. That means every cooling unit on the project needs documentation.
The Broadband Equity, Access, and Deployment (BEAD) program alone allocates $42.5 billion for broadband expansion over the next several years. Every BEAD deployment includes outdoor remote terminal cabinets, fiber distribution hubs, and access network electronics that need climate control to maintain GR-487 compliance. Each of those cooling units must satisfy BABA or be covered by an approved waiver before the federal disbursement can be drawn down.
The same dynamic plays out across the rest of the federal infrastructure portfolio:
- Federal water and wastewater funding flows through state revolving funds to thousands of treatment plants and lift stations, each with control panels, SCADA cabinets, and instrumentation enclosures that need cooling.
- DOT highway and transit grants pay for traffic signal cabinets, ITS roadside cabinets, toll-collection equipment, rail signal houses, and transit station electronics — all of which depend on enclosure climate control.
- DOE grid modernization grants fund substation control buildings, distribution automation cabinets, and reclosers that include conditioned electronics enclosures.
- DoD facility projects use BABA-compliant enclosure cooling for everything from base communications shelters to perimeter security cabinets and fuel-system control panels.
- Federally-funded public buildings and schools use enclosure cooling for building automation, fire alarm systems, and emergency power controls.
If any one of those enclosure air conditioners is not BABA compliant, the contracting officer can disallow the cost, require removal and replacement at the contractor's expense, and in some cases recover federal funds that were already disbursed. The downstream cost of a single non-compliant unit can dwarf the entire purchase price of compliant equipment.

Documentation
How to Verify and Document BABA Compliance
Most federal contracting officers require BABA compliance documentation as part of the equipment submittal package, before the equipment is ordered or installed. The exact format varies by agency, but the documentation almost always includes the manufacturer's certification, country of origin, and a description of how the product satisfies the applicable BABA category.
For enclosure cooling specifically, contracting officers typically want to see:
- A signed compliance letter from the manufacturer on company letterhead
- The manufacturer's federal Tax ID or DUNS/UEI number
- Identification of the manufactured-product category and the applicable threshold
- A statement confirming domestic component cost exceeds 55%
- A statement confirming final assembly in the United States
- The specific model numbers and serial numbers (if available at submittal time)
Sample BABA Spec Language for Enclosure Cooling
Engineers and specifiers can use this language verbatim or adapt it to project requirements. It satisfies the manufactured-product requirement under 2 CFR Part 184 (the OMB’s BABA implementing regulation):
All enclosure air conditioners and heat exchangers furnished under this contract shall comply with the Build America, Buy America Act (Pub. L. 117-58, Sections 70901-70927) and OMB Memorandum M-22-11. Equipment shall qualify as a manufactured product produced in the United States: (a) the manufacturing process for the manufactured product shall occur in the United States; and (b) the cost of components manufactured in the United States shall exceed 55 percent of the total cost of all components.
The manufacturer shall furnish a signed certification on company letterhead confirming domestic manufacturing, percentage of domestic component cost, and country of origin. Acceptable manufacturers include VoltAire (Orlando, FL) or approved equal meeting all BABA requirements.

Get It Right
Common BABA Misconceptions
“Made in USA” on the label means the product is BABA compliant.
These are different standards enforced by different agencies. The Federal Trade Commission’s “Made in USA ” rule requires that “all or virtually all” of a product be made domestically, but it is a marketing claim, not a federal procurement standard. BABA, by contrast, is a procurement compliance regime with specific category thresholds (100% for iron and steel, >55% for manufactured products) and a self-certification process tied to federal financial assistance awards. A product can technically use a “Made in USA” label without meeting BABA requirements, and a BABA-compliant product is not always eligible to make the FTC label claim.
“Our project has a BABA waiver, so we don’t need to worry about it.”
Waivers are narrow, project-specific (or category-specific), and must be formally granted by the funding agency after a public comment period. Always verify the scope of any claimed waiver in writing. A non-availability waiver for one component does not extend to other components on the same project, and a categorical waiver from one agency does not transfer to projects funded by other agencies. When BABA-compliant options are commercially available — as they are for enclosure cooling — waivers are rarely granted and difficult to defend if challenged.
“Small purchases are exempt under a de minimis rule.”
There is a limited de minimis exception under 2 CFR Part 184 for cumulative miscellaneous minor components, but it is far narrower than most contractors assume. The exception applies to the aggregate cost of small unidentified components and is capped at a small percentage of total project cost. It does not exempt enclosure air conditioners, heat exchangers, or other clearly identified equipment line items. Do not rely on de minimis to cover a significant cooling install.
“If domestic costs more, we automatically qualify for the unreasonable cost waiver.”
The unreasonable cost waiver requires a documented showing that domestic content would increase the cost of the overall project (not just the individual line item) by more than 25 percent. The waiver application must be submitted to and approved by the funding agency, then published for public comment, before the waiver takes effect. It is a high bar. For commodity products like enclosure air conditioners, the price difference between BABA-compliant and non-compliant units is usually nowhere near the threshold that would justify a waiver.
“Our equipment is TAA compliant, so we’re fine.”
The Trade Agreements Act and BABA are different regimes with different eligibility rules. TAA compliance recognizes products from designated countries that have qualifying trade agreements with the U.S., including Canada, Mexico, the United Kingdom, Japan, and others. BABA only recognizes products manufactured domestically in the United States. A TAA-compliant unit manufactured in Mexico or Vietnam is not BABA compliant. Federal infrastructure awards almost always require BABA, not TAA.
