This is a request for a Firm Fixed Price quote for specific items, requiring a published online price list or equivalent for price justification. The buyer, Brookhaven Science Associates (BSA) for the Department of Energy, mandates that all vendors be registered in the SAM.gov database at no cost, with specific instructions provided for registration. Products not bought directly from the manufacturer must be sourced from a franchised or licensed distributor, with documentation of that authorization required. The resulting purchase order will be subject to attached terms and conditions.
