UNSPSC 51171622: Sodium phosphate

This classification denotes an electrolyte replacement agent with the molecular formula NAH2PO4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier SE337SVY37, more generally known as sodium phosphate. European Medicines Agency schedules sodium phosphate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB12587MIG. The term SODIUM PHOSPHATE is an International Non-Proprietary Name or INN. see WHO INN reference publication, Volume 25, no. 10 1971, list 11.

Most nations schedule sodium phosphate under HS 28444030 and SITC 52519. As of Q4 2014, SODIUM PHOSPHATE remains the US FDA Preferred Term for this commodity. Sodium phosphate bears US NLM identifiers UMLS ID C0074757 and NCI Concept Code C29459. SMILES: [O-]P(=O)([O-])[O-].[NA+].[NA+].[NA+].

UNSPSC 51171622 Sodium phosphate is a Commodity code that in recent state and local procurement activity covers laboratory reagents and chemical supplies used in drug testing and specimen analysis. Collin County Community Supervision and Corrections Department solicited offender specimen collection and drug testing services under RFP 2026-327, a contract that requires immunoassay screening with LC/MS/MS or GC/MS confirmation — processes that depend on sodium phosphate and related buffer compounds as core reagent inputs. The code appears to function as a catch-all category for chemical consumables supporting clinical laboratory operations rather than as a direct procurement for sodium phosphate itself as a standalone product line. Issuing bodies under this code include county-level corrections and community supervision agencies that manage offender testing programs.

Activity centers in Texas, where Collin County's RFP for offender drug testing services represents the most recent documented opportunity. The Collin County solicitation, posted September 25, 2026 with a response date of July 23, 2026, estimates contract value at $600,000 over two years with three optional one-year renewals, covering approximately 25,031 annual tests across five-panel and six-panel screening formats with confirmation testing at two sites in Plano and McKinney. The contract requires SAMHSA, Texas Department of Public Safety, or CAP lab certification and pricing on a per-test basis across three service models (screening only, confirmation after screening, and screening with automatic confirmation). Beyond this single recent opportunity, the source identifies no additional state and local procurement activity under this Commodity code.
