UNSPSC 51191553: Indapamide

This classification denotes a thiazide diuretic with the molecular formula C16H16ClN3O3S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier F089I0511L, chemically known as 4-chloro-n-(2-methyl-2,3-dihydroindol-1-yl)-3-sulfamoyl-benzamide but generally known as indapamide, which bears US NIH Compound Identifier 3702. European Medicines Agency schedules Indapamide in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08169MIG.

UNSPSC 51191553 Indapamide is a Commodity code that captures pharmaceutical procurement by state and local governments, though recent solicitations under this code show a mismatch between the code's nominal scope and the work actually being bought. The City of Meriden's July 2026 bid for sodium bisulfite chemical supply and the Minnesota Multistate Cooperative Purchasing Alliance's January 2026 RFP for generic multi-source pharmaceuticals and OTC products both carry this code, yet sodium bisulfite is a water-treatment chemical unrelated to pharmaceutical supply. The pharmaceutical RFP is the work most consistent with the code name; MMCAP seeks manufacturers to provide generic drugs and over-the-counter products distributed across participating state and local government facilities in Minnesota and Oregon, requiring suppliers to maintain relationships with three authorized wholesalers (AmerisourceBergen/Cencora, Cardinal Health, and Morris & Dickson) and comply with current Good Manufacturing Practices and the Drug Supply Chain Security Act. The issuing bodies span state procurement offices administering cooperative purchasing vehicles and municipal utilities, reflecting the fragmented buyer base typical of state and local procurement.

The code shows limited recent activity. MMCAP's pharmaceutical RFP, due March 26, 2026, represents a multi-state cooperative purchasing contract with a two-year term and optional extensions through June 30, 2028, with price competitiveness weighted at 75 percent of the evaluation and all vendors required to pay a 3 percent administrative fee. The City of Meriden's solicitation (B027-15) for sodium bisulfite closed July 29, 2026, as an IFB for water treatment chemical supply with General Liability insurance of $1,000,000 to $2,000,000 required. The geographic footprint is limited to Minnesota, Oregon, and Connecticut in recent postings. The code's sparse activity and the apparent mismag between the nominal pharmaceutical scope and the water-treatment chemical solicitation suggest either misclassification by issuing bodies or low procurement frequency under this specific code; business development professionals should verify actual pharmaceutical buying patterns at target jurisdictions rather than relying on this code alone.
