UNSPSC 51191800: Potassium salts

This classification denotes inorganic compounds that contain potassium as an integral part of the molecule.

UNSPSC 51191800 Potassium salts is a Class code that encompasses chemical supply for municipal water treatment and facility operations, based on recent state and local solicitations. The City of Meriden, Connecticut is actively procuring sodium bisulfite—a chemical directly related to potassium salts in function and application context—for water pollution control facility operations under IFB B027-15, due July 29, 2026. State and local governments soliciting under this code are primarily municipal water authorities and utility departments responsible for treatment and pollution control operations. Chemical supply for potassium salts and related compounds serves core water treatment, disinfection, and facility maintenance roles in municipal infrastructure. Contractors must carry General Liability coverage of $1,000,000 to $2,000,000, Auto Liability of $1,000,000, and Umbrella/Excess Liability; the City of Meriden must be named as Additional Insured on a primary and non-contributory basis. Performance and labor/material payment bonds are required, and bid prices must remain firm for the period specified in the bid documents.

Recent activity centers on Connecticut, with the Meriden water facility procurement representing concrete municipal demand. A parallel January 2026 RFP issued by the Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by the Minnesota Department of Administration's Office of State Procurement, tagged this code but solicited generic multi-source pharmaceuticals and OTC products for state and local government facilities across participating jurisdictions including Oregon—a scope mismatch that signals the code shows limited consolidated activity in pharmaceutical supply. The Meriden IFB is the clearest signal of actual potassium salt or related chemical procurement; the MMCAP RFP demonstrates the code receives incidental tagging for unrelated commodities. Geographic concentration appears limited to Connecticut in the current opportunities window.
