Every contract for the construction, alteration, or repair of any public building or public work in the United States shall contain a provision that in the performance of the work the contractor, subcontractors, material men, or suppliers shall use only—

(1) unmanufactured articles, materials, and supplies that have been mined or produced in the United States; and

(2) manufactured articles, materials, and supplies that have been manufactured in the United States substantially all from articles, materials, or supplies mined, produced, or manufactured in the United States.

This section does not apply—

This section does not apply—

(A) to articles, materials, or supplies for use outside the United States;

(B) if articles, materials, or supplies of the class or kind to be used, or the articles, materials, or supplies from which they are manufactured, are not mined, produced, or manufactured in the United States in sufficient and reasonably available commercial quantities and are not of a satisfactory quality; and

(C) to manufactured articles, materials, or supplies procured under any contract with an award value that is not more than the micro-purchase threshold under section 1902 of this title.

(2) Particular article, material, or supply.— If the head of the department or independent establishment making the contract finds that it is impracticable to comply with subsection (a) for a particular article, material, or supply or that it would unreasonably increase the cost, an exception shall be noted in the specifications for that article, material, or supply and a public record of the findings that justified the exception shall be made.

(3) Inconsistent with public interest.— Subsection (a) shall be regarded as requiring the purchase, for public use within the United States, of articles, materials, or supplies manufactured in the United States in sufficient and reasonably available commercial quantities and of a satisfactory quality, unless the head of the department or independent establishment concerned determines their purchase to be inconsistent with the public interest or their cost to be unreasonable.

If the head of a department, bureau, agency, or independent establishment that has made a contract containing the provision required by subsection (a) finds that there has been a failure to comply with the provision in the performance of the contract, the head of the department, bureau, agency, or independent establishment shall make the findings public. The findings shall include the name of the contractor obligated under the contract. The contractor, and any subcontractor, material man, or supplier associated or affiliated with the contractor, shall not be awarded another contract for the construction, alteration, or repair of any public building or public work for 3 years after the findings are made public.
