UNSPSC 51191700: Alkalinizing agents

This classification denotes drugs or other substances that raise blood PH levels.

UNSPSC 51191700 Alkalinizing agents is a Class code that covers chemical supply for municipal water treatment and pollution control operations, including sodium bisulfite and related alkalinizing compounds used to adjust pH and manage water quality in public treatment facilities. State and local governments buy these commodities through municipal water departments and environmental agencies soliciting for ongoing operational supply needs. The work involves supplying specified chemicals in conformance with water-quality standards, meeting delivery schedules, and maintaining appropriate insurance and bonding coverage as required by municipal contracting offices.

Recent activity shows municipal water authorities as the primary issuing bodies under this code. The City of Meriden, Connecticut, issued IFB B027-15 on July 8, 2026, for sodium bisulfite supply to its Water Pollution Control Facility, with bids due July 29, 2026, requiring unit-cost pricing evaluation and performance and payment bonds. Geographic spread is limited in the recent-opportunities block; Connecticut is the only state with a directly relevant solicitation under this code. A separate Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) RFP posted January 20, 2026, was tagged to this code but addresses generic pharmaceuticals and OTC products rather than alkalinizing agents, indicating possible miscoding in the state procurement system. The alkalinizing-agents code shows sparse recent activity among state and local buyers; municipal water and wastewater treatment facilities represent the primary customer base where this code is actively used.
