NSF waiver requests: Build America, Buy America Act


This page includes all of NSF's waivers for the domestic procurement requirements of the "Build America, Buy America Act," and the status of the waivers.

The "Build America, Buy America Act" requires that NSF make a proposed waiver available for a 15-day public comment period before it issues any waiver. Once the public comment period has closed, NSF will consider any comments it received in its evaluation of the waiver request and make a final decision based on guidance from the Office of Management and Budget’s Made in America Office.
