Buy American Preference Requirements
The Buy American Preferences under 49 U.S.C. § 50101 require that all steel and manufactured goods used in Airport Improvement Program (AIP) funded projects be produced in the United States. In accepting AIP funding, grant recipients must certify that all steel or manufactured products used on any portion of the AIP-funded project are produced in the United States and are of 100 percent U.S. materials.
Under 49 U.S.C. § 50101(b), FAA has the authority to waive these Buy American Preferences if certain market or product conditions exist. These are:
- Applying the Buy American Preferences would be inconsistent with the public interest;
- The steel or goods produced in the U.S. are not produced in a sufficient and reasonably available amount or are not of a satisfactory quality;
- When the cost of components and subcomponents produced in the U.S. is more than 60 percent of the cost of all components of the facility or equipment procured and final assembly occurs in the United States; or
- Including domestic material will increase the cost of the overall project by more than 25 percent.
