UNSPSC 51191500: Diuretics

This classification denotes agents or substances that promote excretion of urine by influencing human kidney function, commonly known as DIURETICS. The major diuretic types include osmotic (diuretics that increase urine volume by increasing osmotically-active urine solute); potassium sparing (diuretics that limit potassium secretion in urine); sodium chloride symporter inhibitors; and sodium potassium chloride symporter inhibitors.

Diuretics, that is, operate by stimulating he nervous system, by alleviating kidney congestion, by increasing blood pressure, or by increasing or improving liquid transport.

UNSPSC 51191500 Diuretics is a Class code that in recent state and local procurement activity encompasses pharmaceutical and chemical products for healthcare, correctional, and municipal water-treatment operations — a scope that diverges markedly from the code's nominal pharmaceutical focus. State and local health systems, correctional departments, and water utilities are the primary buyers. The Washington State Department of Corrections solicited parenteral products, services, and equipment including parenteral nutrition solutions, intravenous solutions, and controlled substances for incarcerated individuals; the City of Meriden sought sodium bisulfite chemical supply for water-treatment operations; and Broward County, Florida issued a Request for Information on industrial control valves and repair services for wastewater treatment facilities. The code's recent activity spans correctional healthcare delivery, municipal water and wastewater treatment, and chemical supplies — a functional mix broader than the code name suggests, indicating that state and local procurement offices are tagging diverse chemical and supply-chain work under this Class designation.

Geographic activity centers on Washington State, Florida, and Connecticut based on recent postings. The Washington State Department of Corrections RFQ for parenteral products, services, and equipment (RFQQK13020) closes October 7, 2026, with a pre-bid conference on September 23, 2026; bidders are encouraged to participate as small businesses (25%), minority-owned businesses (10%), women-owned businesses (6%), and veteran-owned businesses (5%), with DOC anticipating multiple awards of up to three bidders per region across eight facilities spanning West, Central, and East regions, with an initial contract term running November 26, 2026 through June 30, 2030. Broward County's RFI on DeZurik/APCO valves, parts, and repair services (BLD6232026F23) closed September 29, 2026, seeking to determine sole-source justification for wastewater treatment control systems. The City of Meriden's sodium bisulfite bid (B027-15) had a due date of July 29, 2026 for municipal water pollution control operations.
