The U.S. Embassy in Belgium intends to establish a Blanket Purchase Agreement for Plumbing Fixtures and Accessories, which is not a standard contract but an overarching agreement for future service requests. Companies must specialize in this field and provide indicative pricing. Performance of services is specified for Belgium. A mandatory requirement is registration in the SAM.gov system for any business valued over $40,000, which involves obtaining an NCAGE code at no cost. Interested parties must submit their pricing information by a specified deadline via email.
