The U.S. Army Corps of Engineers Baltimore District is seeking sources for the procurement of Fluorosilicic Acid 25% in bulk liquid form for the Washington Aqueduct. This pre-solicitation notice indicates that USACE is planning a re-procurement of an indefinite-delivery indefinite-quantity (IDIQ) contract, which will be structured as a Single Award Task Order Contract (SATOC). The procured fluorosilicic acid must meet the requirements of ANSI/AWWA Standard B300 and must be certified to meet NSF/ANSI Standard 60, ensuring compliance with established water treatment chemical standards. While specific evaluation criteria are not detailed in this notice, the pre-solicitation serves to gauge market interest and solicit feedback from potential contractors regarding capability and capacity. The due date for responses to this sources sought notice is November 28, 2025, providing interested parties a three-day window from the posting date of November 25, 2025 to submit their feedback.

This procurement carries no set-aside designation, meaning it is open to all qualified contractors regardless of small business status. The applicable NAICS code is 325180 (Other Basic Inorganic Chemical Manufacturing), which carries a small business size standard of 1,000 employees, indicating that firms within this category may qualify as small businesses for federal contracting purposes. The pre-solicitation notice does not identify any current incumbents or provide specific budget information or quantity requirements at this stage. The contract will have a five-year ordering period once awarded, allowing for extended supply relationships and planning stability. No specific award value or minimum purchase guarantees are outlined in this sources sought phase, as the IDIQ structure typically allows flexibility in ordering volume based on government requirements throughout the contract period.
