UNSPSC 51191503 Metolazone is a Commodity code covering pharmaceutical and chemical products used in water treatment and healthcare settings. State and local procurement activity under this code reflects divergent use cases: municipal water pollution control facilities source treatment chemicals like sodium bisulfite for operational processes, while state cooperative purchasing alliances procure generic pharmaceuticals and over-the-counter products for distribution across government health and social service facilities. The issuing bodies include city water departments, state departments of administration overseeing cooperative purchasing vehicles, and multi-state procurement consortia coordinating supply chains across member jurisdictions.

Recent opportunities show activity in Connecticut and Minnesota. The City of Meriden issued an IFB (solicitation B02715) for sodium bisulfite chemical supply to its Water Pollution Control Facility with a response date of July 29, 2026, requiring $1,000,000 to $2,000,000 in General Liability coverage and performance and payment bonds. The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by the Minnesota Department of Administration's Office of State Procurement, issued an RFP (S1070000015802) to establish multiple contracts for generic multi-source pharmaceuticals and OTC products effective July 1, 2026, with responses due March 26, 2026; the RFP specifies mandatory distribution through three authorized wholesalers (AmerisourceBergen Drug Corporation, Cardinal Health, and Morris & Dickson Co., LLC), requires cGMP and Drug Supply Chain Security Act compliance, and weights price competitiveness at 75 percent of the evaluation score.
