UNSPSC 51171525: Magnesium oxide

This classification denotes a nutritional supplement and laxative, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 3A3U0GI71G, chemically known as oxomagnesium, but generally known as magnesium oxide, which bears US NIH Compound Identifier 14792. European Medicines Agency schedules Magnesium oxide in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB14436MIG. Magnesium oxide generally arises in the molecular formula MGO.

The term MAGNESIUM OXIDE is a United States Homeopathic Pharmacopoeia Name designation. As of Q4 2014, MAGNESIUM OXIDE remains the US FDA Preferred Term for this commodity. Magnesium oxide bears US NLM identifiers UMLS ID C0024477 and NCI Concept Code C29242. SMILES: O=[Mg].

UNSPSC 51171525 Magnesium oxide is a Commodity code that in recent state and local procurement appears to be mistagged — the single recent opportunity under the code is Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services, which involves no magnesium oxide procurement and falls outside the code's nominal scope of chemical raw materials. The opportunity instead calls for staffing two collection sites in Plano and McKinney, operation of an Interactive Voice Response system for randomized testing notifications, immunoassay screening with LC/MS/MS or GC/MS confirmation, electronic result reporting, and alternative testing methodologies including oral fluid and hair testing. Annual testing demand is approximately 25,031 tests comprising five-panel and six-panel screens plus ancillary testing. The successful vendor must maintain lab certification from SAMHSA, TX DPS, or CAP, and pricing is submitted on a per-test basis with three service models: screening only, confirmation after screening, and screening with automatic confirmation of positives. All pricing must include freight, delivery, insurance, and staffing costs with no additional surcharges permitted. The estimated contract value is $600,000 over two years commencing September 1, 2026, with three optional one-year renewal periods not to exceed five years total.

This code shows little relevant recent activity aligned with its stated commodity classification. The Collin County opportunity posted September 25, 2026 with a response deadline of July 23, 2026 (a historical due date that predates the posting) and an anticipated award date of August 10, 2026, represents drug testing services procurement rather than chemical materials sourcing. No other recent state or local solicitations under UNSPSC 51171525 are present in the source, and the geographic and issuing-body mix cannot be characterized from a single misaligned opportunity. Business development professionals should verify whether this code is actively used for magnesium oxide procurement in their target jurisdictions, as current market signals suggest minimal or no relevant activity.
