Section 1605 of the Recovery Act prohibits use of recovery funds for a project for the construction, alteration, maintenance, or repair of a public building or public work unless all of the iron, steel, and manufactured goods used in the project are produced in the United States. The law requires that this prohibition be applied in a manner consistent with U.S. obligations under international agreements, and it provides for waiver under three circumstances:
Iron, steel, or relevant manufactured goods are not produced in the United States in sufficient and reasonably available quantities and of a satisfactory quality;
Inclusion of iron, steel, or manufactured goods produced in the United States will increase the cost of the overall project by more than 25 percent; or
Applying the domestic preference would be inconsistent with the public interest.
