UNSPSC 51172306 Sodium polystyrene sulfonate is a Commodity code under which state and local governments procure drug-testing and specimen-collection services, not the chemical compound itself. Collin County Community Supervision and Corrections Department's RFP 2026-327 illustrates the actual scope: the county is soliciting staffing for two offender drug-testing sites, operation of automated randomized testing notification systems, immunoassay screening with confirmatory testing (LC/MS/MS or GC/MS), electronic result reporting, and alternative matrices including oral fluid and hair testing. The code appears in practice to span criminal justice and corrections specimen-collection work performed by county and municipal public-safety agencies. Vendors must hold SAMHSA, Texas DPS, or CAP lab certification and maintain chain-of-custody and reporting infrastructure to meet regulatory and supervisory requirements.

The recent record shows activity concentrated in Texas, specifically Collin County's two-year initial contract (commencing September 1, 2026) with three optional one-year renewals for approximately 25,031 annual tests and an estimated value of $600,000. Collin County Community Supervision and Corrections Department issued RFP 2026-327 with proposals due July 23, 2026 at 2:00 p.m.; the anticipated award date was August 10, 2026. Pricing is submitted per-test across three service models (screening only, screening plus confirmation, or screening with automatic confirmation of positives), with all costs including freight, delivery, insurance, and staffing bundled into unit price—no surcharges permitted. Price redetermination is limited to September 1 anniversaries and capped at 3.0 percent annually based on medical Consumer Price Index movement. Evaluation weights vendor understanding (30 points), firm qualifications (25 points), client references (15 points), cost (30 points), and optional demonstrations and interviews (up to 30 points). The contract was funded through Texas Department of Criminal Justice-Community Justice Assistance Division appropriations subject to annual availability.
