BABA manufactured products: the 55% component-cost test

Buyers often treat every fixture, cabinet, pump, and precast unit as a construction material — or run a 55 percent spreadsheet on rebar. 2 CFR Part 184 does neither. A manufactured product is its own category, with a two-part “produced in the United States” test: manufactured in the United States, and the cost of U.S. components greater than 55 percent of all components.

This briefing is for buyers and suppliers who have to classify an item before the shop-drawing fight. Use the BABA / Buy America applicability check for a funding-type sketch, then read the award. It is educational, not legal advice and not official OMB or agency guidance. See BABA basics for infrastructure projects for the three-category map and BABA construction materials: what counts for the closed list that this category is not.

What counts as a manufactured product

Under 2 CFR 184.3, a manufactured product is an article, material, or supply that has been processed into a specific form and shape, or combined with other articles to create a product with different properties than the individual inputs.

That definition is the residual bucket. If the item is already classified as an iron or steel product, a construction material, or a section 70917(c) material, it is not a manufactured product. A manufactured product may still contain iron or steel, listed construction materials, or 70917(c) materials as components. The preference then follows the manufactured-product test for the item as a whole — not a second, separate test on each input as if that input arrived at the site alone.

2 CFR 184.4(e) says an article should fall into one category only:

• Iron or steel products
• Manufactured products
• Construction materials
• Section 70917(c) materials (cement, cementitious materials, aggregates, aggregate binders)

Classification is made on the item’s status when it is brought to the work site for incorporation — generally the project location, not the mill, the warehouse, or a line on a bill of materials. Do not classify the same delivery as both a construction material and a manufactured product.

A control cabinet, a pump, a generator, a precast structure, and a factory-assembled lighting pole are the usual manufactured-product facts. A stick of lumber, a coil of rebar, and a bag of cement are not — those sit in the construction-material, iron-or-steel, or 70917(c) buckets if they arrive that way.

The two-part produced-in-the-U.S. test

For manufactured products, “produced in the United States” is not an all-processes test. 2 CFR 184.5 requires both of the following, unless another law or regulation sets a higher domestic-content bar for that award:

1. The product was manufactured in the United States. Final manufacture — the processing or combination that makes the item the manufactured product — happened here.
2. 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 of that manufactured product.

Greater than 55 percent means 55.0 percent fails. The domestic content threshold helper runs that “greater than” arithmetic and the all-processes screens used for iron, steel, and construction materials. It does not classify your item, and it does not turn a FAR Buy American 65 or 75 percent figure into a BABA finding. Those percentages are a different statute. Do not drop a FAR number onto a BABA award unless the award itself does.

How 2 CFR 184.5 counts component cost

A component is an article, material, or supply — manufactured or not — that is directly incorporated into the manufactured product.

The cost of a component is:

• Purchased components. Acquisition cost, including transportation to the place of incorporation into the manufactured product, and any applicable duty.
• Components the manufacturer makes itself. All costs associated with manufacturing that component, including that transportation, plus allocable overhead — excluding profit. Do not fold in the cost of manufacturing the end product.

The denominator is the total cost of all components, domestic and foreign. Assembly labor, manufacturer profit on the end product, and other end-product manufacturing costs are not component costs. A supplier who only has a sales price, or a buyer who only has a lump-sum quote, does not yet have the 184.5 math.

Keep invoices, freight to the incorporation point, and a written good-faith allocation when a component is close to the line. The regulation is a cost test, not a weight test and not a “feels mostly American” test.

How this differs from iron or steel and construction materials

The practical split:

• Iron or steel product — wholly or predominantly iron or steel (the iron and steel content exceeds 50 percent of the total cost of all components). Test: all manufacturing processes from the initial melting stage through the application of coatings in the United States. That is the mill-and-coat rule desks already know from FHWA 23 U.S.C. 313.
• Construction material — one item on the closed 184.3 list (non-ferrous metals, plastic and polymer-based products, glass, fiber optic cable, optical fiber, lumber, engineered wood, drywall), with only minor additions. Test: all manufacturing processes in the United States under 2 CFR 184.6. There is no 55 percent component-cost percent.
• Manufactured product — processed or combined, and not in the other three buckets. Test: U.S. manufacture and greater than 55 percent domestic component cost (184.5).
• Section 70917(c) — cement, cementitious materials, aggregates, or aggregate binders. Outside the BABA preference unless another program says otherwise.

Do not run a pump through melt-through-coating. Do not run a steel beam through the 55 percent spreadsheet. Do not run a drywall panel through 184.5. Highway lettings can still be FHWA Buy America jobs and BABA jobs; manufactured-product coverage and FHWA’s own manufactured-product phase-in are the pieces that change with letting date. The applicability tool flags the overlay. It does not date your bid. See FHWA Buy America nonavailability waivers.

A manufactured product that contains steel, PVC, or cement as components is still one manufactured product at the work site. Apply 184.5 to that product. Do not re-test each input under 184.6 or melt-through-coating unless that input is what actually arrives for incorporation.

What buyers and suppliers should check

Before you write a spec note, a bid exception, or a waiver request, walk the item — not the CSI division.

• Funding. Federal financial assistance for an infrastructure project in the United States is the BABA on-ramp. Direct FAR procurement is a different statute. The applicability check sketches the regime; the assistance agreement controls.
• Category at the work site. One of four: iron/steel, manufactured product, construction material, or 70917(c). Not two. Not “construction materials” as a synonym for the jobsite pile.
• If it is iron or steel. Melt through coating. Predominantly iron/steel is a cost test (exceeds 50 percent of component cost), not a vibe.
• If it is on the 184.3 construction-material list. Apply the matching 184.6 process window. See what counts as a construction material.
• If it is a manufactured product. Confirm U.S. manufacture and run the 184.5 component-cost math. Collect invoices and freight to the incorporation point. Separate purchased-component acquisition cost from self-made-component manufacturing cost. Exclude end-product profit and end-product manufacturing cost from the component pool. Use the domestic content helper for the greater-than-55 percent arithmetic — then keep the workpapers.
• If it is cement, aggregate, or an aggregate binder. Treat it as 70917(c) unless the award or another statute says otherwise. Once those items are combined into a manufactured product that arrives as that product, the preference follows 184.5, not 184.6.
• Waivers. Agencies can still waive manufactured products for public interest, nonavailability, or 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 FHWA Buy America nonavailability waivers. The comment-deadline countdown and batch helper count Eastern Time calendar days; they do not replace the cutoff on the notice. The keyword note builder is for one-off research strings, not a filing.

Buyers: put the preference in the bid documents, flow it to subcontractors, and classify before procurement locks a foreign assembly. Suppliers: know whether you sell a manufactured product or a listed construction material, and keep the invoices that match the test you are actually under. A good-faith cost file is cheaper than a mid-letting reclass.

None of this is a coverage opinion. Confirm 2 CFR Part 184, the agency’s implementing guidance, and the award clause. The articles are background. The tools hub is arithmetic. A Flagcup desk emails the official notice when a matching waiver posts.
