What BAA says:
The Buy American Act of 1933 (BAA) restricts the Federal government from purchasing non-domestic goods by establishing a preference for “domestic end products” and use “domestic construction materials”. Generally, the BAA applies to Federal acquisitions that exceed the micro-purchase threshold and that are below the applicable dollar threshold for Trade Agreement Act (TAA) applicability.*
The recipient of the funding, rather than Signify, has the ultimate responsibility of identifying the applicable domestic preference requirement, e.g., BAA, TAA or Buy America. The applicable requirement is typically identified in the RFP/project documentation.
