Key takeaways
- October 1, 2026 is a new implementation phase for FHWA’s manufactured-products requirements.
- The relevant trigger is the covered project’s obligation date, not the dealer’s quote date.
- Product classification comes before a sourcing promise. Stone aggregate and a finished hardscape component should not be casually treated as interchangeable categories.
- A domestic shipping address is not evidence of domestic manufacture.
- Build the required documentation into the inquiry before releasing a material order.
“Can you quote a domestic product?” sounds like a simple purchasing question. On a covered Federal-aid highway project, it can require several separate answers: what the delivered item is, which category governs it, when the project was obligated and what evidence the recipient requires.
For Tri-State dealers supplying contractors and municipal teams, the useful response is a structured request for information. A product’s appearance, a warehouse location or a familiar supplier name cannot settle the project’s eligibility review.
What actually changed on October 1
Under 23 CFR 635.410, covered manufactured products for projects obligated on or after October 1, 2026 must meet U.S. manufacturing and a domestic component-cost threshold greater than 55 percent. “Greater than” matters: exactly 55 percent is not the stated test.
The final rule was published January 14, 2025, with an effective date of March 20, 2025. The October milestone is its phase-in, not a newly announced rule. The preceding phase began with projects obligated on or after October 1, 2025 and required U.S. manufacture for covered manufactured products.
These are Federal-aid highway requirements. They should not be presented as a universal rule for every park, private development, homeowner order or municipal purchase. Other domestic preferences may govern other contracts; the actual funding and incorporated clauses must be established.
Start with the delivered item, not the sales category
The question “Is stone exempt?” is too broad to release an order. A sales catalog groups products by use and appearance. Procurement rules classify items using different definitions.
2 CFR 184.3 addresses excluded materials including aggregate such as stone, sand or gravel. But a reference to stone aggregate does not establish how every cut, combined or processed architectural item will be classified. The FHWA Q&A explains that the item’s status when brought to the worksite matters.
Ask the recipient or authorized project reviewer to identify the governing category. Supply a precise description of the proposed delivered item, its composition and processing. Where the determination is unclear, keep the quote conditional on that review rather than inventing an exemption.
Separate four questions in the inquiry
| Question | Evidence to request | What it does not establish alone |
|---|---|---|
| Where does the order ship from? | Shipping point and freight terms | Manufacturing location |
| Where is the product manufactured? | Manufacturer’s process/location statement | Required component-cost compliance |
| What is the delivered product category? | Recipient’s determination and contract clause | Eligibility under every funding program |
| Who accepts the documentation? | Named reviewer and required certification form | Automatic acceptance of a substitute |
This table is a recommended purchasing workflow. The project’s issued requirements govern the actual submission.
Why a domestic warehouse is not enough
The January 2026 FHWA guidance distinguishes manufacturing from repackaging or relabeling imported products. This makes a supplier’s domestic address useful contact information, but an incomplete origin answer.
A dealer should ask the manufacturer for the project-required statement rather than try to recreate manufacturing history from a packing slip. Keep the manufacturer’s identity, product reference and submitted evidence connected. If a customer changes the product, plant or configuration, send the revision back through the approval process.
Keep the cost test with the appropriate evidence
The threshold concerns component cost under the regulation. It does not measure the portion of the retail invoice retained in the United States. Dealer margin, domestic freight and a final selling price cannot be casually combined into a substitute calculation.
Request the manufacturer’s determination in the form the recipient requires. Do not promise access to proprietary costing or guarantee acceptance of a particular certificate. Record who supplied the evidence and who accepted it.
A practical prequote checklist for dealers
Before turning a public-project inquiry into a firm release, request:
- Project name, recipient, funding program and applicable obligation date.
- Issued specifications, domestic-preference clauses and required submission forms.
- Recipient classification of the exact delivered product.
- Manufacturer, product reference, manufacturing location and component evidence required by the project.
- Authorized reviewer, submission deadline and approval sequence.
- Any project-specific waiver determination, with its conditions and supporting record.
- Quantity, dimensions, finish, delivery stages and substitution procedure.
The final item matters commercially. A compliant documentation package does not establish the right dimensions or finish. Conversely, an approved appearance sample does not establish domestic-preference compliance. Track the two reviews separately and join them before release.
Use a release gate instead of a vague promise
A recommended order note is: “Material release requires acceptance of the specified product and required project documentation by the authorized reviewer.” Adapt that language to the actual contract rather than using it as a substitute for legal or procurement review.
Keep an inquiry log with the requested product, pending evidence, reviewer and next decision date. When a contractor asks for an alternate, identify both the physical differences and the documentation that must be resubmitted. Confirm actual supplier availability and lead time independently; this rule does not establish either.
For dealers serving Long Island, NYC, New Jersey and Connecticut, the opportunity is to make the material conversation more complete. It is not evidence of a new purchase order, an open bid or any StoneWorks product’s eligibility.
Frequently Asked Questions
What changed in FHWA Buy America on October 1, 2026?
For covered Federal-aid highway projects obligated on or after October 1, 2026, manufactured products must be manufactured in the United States and the cost of U.S.-mined, produced or manufactured components must exceed 55 percent of total component cost. Confirm applicability with the project recipient.
Does the date a dealer quotes the order determine the phase?
No. The regulation uses the project obligation date for the manufactured-products phase-in. Ask the project recipient for that date and the governing contract requirements before assigning a documentation standard.
Does Buy America automatically apply to every municipal stone order?
No. This article concerns FHWA requirements for covered Federal-aid highway projects. Other public contracts can have different funding conditions and domestic-preference clauses. Read the actual project documents.
Are all stone products treated as excluded aggregate?
Do not assume that. The rules distinguish excluded materials, construction materials and manufactured products, and classification depends on the item’s status when brought to the worksite. Obtain the project recipient’s classification for the proposed product.
Does U.S. warehousing or relabeling establish U.S. manufacture?
No. FHWA’s Q&A explains that repackaging or relabeling an imported product in the United States does not constitute manufacturing. Request evidence of the actual manufacturing process and location.
Is the greater-than-55-percent test based on the retail selling price?
No. It is a component-cost test under the regulation, not a percentage of the dealer’s retail price. Request the manufacturer’s supporting determination and use the project’s required certification process.
