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 GA106. This VA Drug Class (GA106) classifies this compound as belonging to the group CALCIUM/MAGNESIUM CONTAINING ANTACIDS.

UNSPSC 51172455 Calcium carbonate/magnesium carbonate/magnesium oxide is a Commodity code showing a significant mismatch between its nominal scope and recent state and local procurement activity. The single recent opportunity posted under this code — Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services — involves no chemical reagents or mineral compounds at all. The solicitation covers staffing collection sites, operating notification systems, conducting immunoassay and confirmatory testing (LC/MS/MS and GC/MS), and providing oral fluid and hair testing methodologies, with an estimated contract value of $600,000 over two years plus up to three optional one-year renewals. This procurement is fundamentally a laboratory and field services contract, not a materials procurement, and does not align with the code's chemical commodity classification.

The geographic activity supporting this code is limited to Texas, with Collin County as the sole visible issuing body in the recent-opportunities dataset. Collin County posted RFP 2026-327 on September 25, 2026, with a response deadline of July 23, 2026 (note: the due date predates the posting date in the source record, suggesting a data error or amended timeline). Evaluation will be conducted in phases, scoring vendor understanding (30 points), firm qualifications (25 points), client references (15 points), and cost (30 points), with optional Phase 2 demonstrations and interviews worth up to 30 points. The successful vendor must hold lab certification from SAMHSA, TX DPS, or CAP and deliver annual testing volumes of approximately 25,031 tests. Funding is subject to annual availability from Texas Department of Criminal Justice-Community Justice Assistance Division appropriations, with an anticipated award date of August 10, 2026. The code shows no recent relevant activity and appears to be a miscoding of the underlying procurement; business development professionals should confirm UNSPSC alignment before investing pursuit effort.
