UNSPSC 51171522: Calcium lactate

This classification denotes a nutritional supplement with the molecular formula 2C3H5O3.Ca, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 2URQ2N32W3, chemically known as propanoic acid, 2-hydroxy-, calcium salt (2:1) but generally known as calcium lactate, which bears US NIH Compound Identifier 13144. European Medicines Agency schedules Calcium lactate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB13184MIG.

UNSPSC 51171522 Calcium lactate is a Commodity code whose recent state and local posting shows a material mismatch between the code's nominal scope and actual procurement activity. The single recent opportunity recorded under this code is Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services — a procurement centered on laboratory testing protocols, staffing, and result reporting rather than calcium lactate as a chemical ingredient or pharmaceutical input. The scope includes immunoassay screening with confirmatory testing via LC/MS/MS or GC/MS, operation of an Interactive Voice Response system for randomized test notifications, and alternative testing methodologies including oral fluid and hair analysis. The contract calls for operation of two collection sites in Plano and McKinney during weekday business hours plus five Saturdays annually, processing approximately 25,031 tests annually across five-panel and six-panel screening formats. The successful vendor must hold lab certification from SAMHSA, the Texas Department of Public Safety, or the College of American Pathologists. Pricing is per-test with three service models (screening only, confirmation after screening, and screening with automatic confirmation of positives), and all costs including freight, delivery, insurance, and staffing must be incorporated into the per-test rate with no additional surcharges permitted.

The opportunity is isolated to Texas, specifically Collin County, with a response deadline of July 23, 2026 and an estimated annual contract value of $600,000 over an initial two-year term with three optional one-year renewals. Award criteria weight vendor understanding and qualifications at 30 and 25 points respectively, client references at 15 points, and cost at 30 points, with optional Phase 2 demonstrations worth up to 30 additional points. The code shows little relevant recent activity aligned with its nominal calcium lactate scope; the single posting reflects either a classification error in the state and local procurement system or incidental mention of calcium lactate as a minor testing component rather than the primary procurement category.
