UNSPSC 51191802: Potassium chloride

This classification denotes an electrolyte replacement agent, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 660YQ98I10. European Medicines Agency schedules Potassium chloride in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB12559MIG. Potassium chloride generally arises in the molecular formula CLK. The term 'potassium chloride' is a United States Homeopathic Pharmacopoeia Name designation. As of Q4 2014, POTASSIUM CHLORIDE remains the US FDA Preferred Term for this commodity.

Potassium chloride bears US NLM identifiers UMLS ID C0032825 and NCI Concept Code C47679. SMILES: [CL-].[K+].

UNSPSC 51191802 Potassium chloride is a Commodity code representing chemical supplies for municipal water and wastewater treatment operations. State and local governments procure potassium chloride and related inorganic chemicals—including sodium bisulfite and similar treatment compounds—for water pollution control facilities, municipal water systems, and public health infrastructure. The issuing bodies include municipalities and municipal utilities (represented by water pollution control facilities), state health and human services departments, and cooperative purchasing alliances administering multi-jurisdictional chemical supply contracts. Procurement typically occurs through competitive bid solicitations (IFB or RFQ format) with unit-cost evaluation, firm pricing periods, and insurance and bonding requirements standard to public works chemical supply.

Recent activity appears concentrated in the Northeast and Upper Midwest. The City of Meriden, Connecticut issued IFB B027-15 for sodium bisulfite supply to its Water Pollution Control Facility with a bid due date of July 29, 2026, requiring General Liability and Auto Liability coverage of $1,000,000 to $2,000,000 and a performance bond. The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by the Minnesota Department of Administration's Office of State Procurement, issued RFP S1070000015802 in January 2026 for generic multi-source pharmaceuticals and OTC products distributed across participating state and local government facilities including Oregon, with proposals due March 26, 2026—though this latter opportunity appears tagged to this UNSPSC code despite its pharmaceutical rather than potassium-chloride focus, suggesting the code may capture a broader range of chemical and pharmaceutical supply beyond its nominal name.
