UNSPSC 51191560 Methazolamide is a Commodity code that encompasses pharmaceutical and chemical products used in state and local government operations, though recent solicitations under this code reflect a broader range of pharmaceutical and chemical procurement than the code name alone suggests. State and local governments solicit under this code for generic pharmaceuticals, over-the-counter products, and chemical supplies for water treatment and pollution control operations. The issuing bodies span state cooperative purchasing alliances, municipal water and wastewater utilities, and multi-state health and procurement networks. The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by the Minnesota Department of Administration's Office of State Procurement, represents a significant buyer category for pharmaceutical products distributed across participating state and local government facilities.

Recent activity shows geographic concentration in the upper Midwest and Connecticut. The Minnesota Multistate Cooperative Purchasing Alliance issued an RFP on January 20, 2026, due March 26, 2026, to establish multiple contracts for generic multi-source pharmaceuticals and over-the-counter products for distribution across participating state and local government facilities, including Oregon, with awarded vendors effective July 1, 2026 and a two-year contract term. The City of Meriden, Connecticut, posted an IFB (solicitation B02715) on July 8, 2026, due July 29, 2026, for sodium bisulfite chemical supply for its Water Pollution Control Facility, specifying unit-cost pricing evaluation and requiring General Liability coverage of $1,000,000 to $2,000,000, Auto Liability of $1,000,000, and performance and payment bonds. The MMCAP procurement requires cGMP and Drug Supply Chain Security Act compliance, products available by May 15, 2026, and contractual relationships with at least two of three authorized wholesalers; pricing is weighted at 75 percent of evaluation criteria with a 3 percent administrative fee on all purchases.
