Evaluating Foreign Construction Materials: FAR 25.204 Price Penalties
When federal solicitations fall under the Buy American statute, contractors face specific evaluation rules if they plan to use materials sourced outside the United States. Under FAR 25.204, contracting officers do not simply accept or reject bids containing foreign materials out of hand. Instead, they apply a structured price evaluation penalty to balance foreign and domestic options. Knowing how this math works allows trade contractors, estimators, and project managers to price proposals accurately, structure alternate bids, and prevent unexpected penalties on federal jobs.
The Standard 20 Percent Factor on Foreign Materials
For standard construction supplies that are not designated as critical items and do not contain critical components, federal agencies use a standard mathematical penalty. Under FAR 25.204(b)(1)(i), unless the head of the agency specifies a higher percentage, the contracting officer adds 20 percent of the cost of the proposed foreign construction material to the contractor's offered price. This adjustment is applied when the contractor seeks an exception based on the unreasonable cost of domestic construction materials.
This penalty is added strictly to the proposed foreign material cost, not to the entire contract price. For instance, if an interior subcontractor's bid includes foreign materials that an offeror requests an exception for, the contracting officer increases the total evaluated bid by 20 percent of that foreign material's cost. Furthermore, if applying this evaluation factor results in a tie between a foreign-inclusive bid and a domestic bid, the contracting officer must award preference to the offer that does not rely on an unreasonable-cost exception for foreign materials.
Additional Penalties for Critical Items and Critical Components
Federal procurement assigns heightened protection to specific supply chains. When the construction material involves a critical item or contains critical components listed in FAR section 25.105, the evaluation penalty increases beyond the baseline rate.
According to FAR 25.204(b)(2)(i), the contracting officer must add 20 percent plus an additional preference factor identified for that specific critical item or critical component. Estimators reviewing project specifications must check FAR 25.105 to see if any specified interior assemblies, structural products, or MEP items carry this additional evaluation factor. Just as with standard materials, any tie score involving a critical-item exception gives precedence to the offeror utilizing domestic construction material.
The 55 Percent Domestic Content Evaluation Procedure
FAR 25.204 outlines a specific fallback procedure for non-COTS construction materials that do not consist wholly or predominantly of iron or steel. This multi-step process applies when evaluating low bids:
- If applying standard evaluation factors shows domestic material cost is unreasonable, or if the agency receives no domestic offers; and
- The lowest offer proposes foreign construction material containing 55 percent or less domestic content; then
- The contracting officer must treat the lowest offer of foreign material manufactured in the United States that exceeds 55 percent domestic content as a domestic offer; and
- The officer determines the reasonableness of that offer by applying the evaluation factor to the lowest foreign offer.
Under FAR 25.204(b)(1)(iii) and FAR 25.204(b)(2)(iii), this 55 percent domestic content evaluation procedure will sunset and no longer apply as of January 1, 2030.
Protecting Bids by Submitting Domestic Alternates
Relying solely on an agency approving an unreasonable-cost exception puts a bid at risk. Under FAR 25.204(c), offerors are explicitly permitted to submit alternate offers based on equivalent domestic construction materials. Providing a compliant domestic alternative ensures your bid remains viable even if the contracting officer determines the foreign material exception does not apply. Review our guides on Buy American on Federal Construction Bids and structuring proposals and bid exclusions to document both options cleanly without making your pricing conditional.
If an agency does accept a foreign material proposed under an exception, FAR 25.204(d) requires the contracting officer to add that material to the list of excepted items in the contract clause, such as paragraph (b)(2) of FAR 52.225-9 or paragraph (b)(3) of FAR 52.225-11.
Postaward Determinations and Price Adjustments Under FAR 25.205
Contractors cannot easily switch to foreign materials after receiving an award. Under FAR 25.205(a), any contractor requesting a postaward determination that the Buy American statute does not apply must explain why the request could not be made before award or why the need was not reasonably foreseeable. If the contracting officer finds that the contractor should have identified the issue prior to award, the officer may deny the request.
When an exception is approved postaward under FAR 25.202(a), the contractor does not simply keep the material savings. Under FAR 25.205(c), the contracting officer must negotiate adequate consideration and modify the contract. If the exception is granted because domestic materials are unreasonably priced, adequate consideration is at least the differential established in FAR 25.202(a) or agency procedures, effectively returning the cost differential to the government.
