UNSPSC 51173233: Potassium bitartrate/sodium bicarbonate

This classification denotes a combination drug defined by the U.S. Department of Veterans Affairs in its (VA's) National Drug File (NDF), which falls under VA Drug Class RS300. This VA Drug Class (RS300) classifies this compound as belonging to the group LAXATIVES, RECTAL.

UNSPSC 51173233 Potassium bitartrate/sodium bicarbonate is a Commodity code showing minimal alignment with recent state and local procurement activity. The code nominally describes a specific chemical compound used in pharmaceuticals and food processing, but the three most recent opportunities posted under or near this classification involve offender drug testing services, direct-to-manufacturer pharmacy initiatives, and generic multi-source pharmaceutical distribution — none of which directly procure potassium bitartrate or sodium bicarbonate as a discrete product. The mismatch suggests either miscoding by issuing bodies or that this code has limited contemporary relevance in state and local procurement.

The single opportunity closest to testing-related chemistry is Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services, posted July 9, 2026, with proposals due July 23, 2026. The county seeks approximately 25,031 annual tests (primarily five- and six-panel immunoassay screens with LC/MS/MS or GC/MS confirmation) under a two-year contract commencing September 1, 2026, estimated at $600,000, with optional renewals through five years total. The other two opportunities — Texas HHS Commission's RFI on direct-to-manufacturer prescriptions and Minnesota's MMCAP cooperative purchasing RFP for generic pharmaceuticals and OTC products, posted January 20, 2026 with responses due March 26, 2026 — involve pharmacy benefit program management and multi-state distribution, not the potassium bitartrate/sodium bicarbonate commodity itself. No recent state or local solicitations directly procure this chemical compound, and pursuit under this code would require clarification of actual material specifications from issuing bodies.
