UNSPSC 51171722 Diphenoxylate hydrochloride is a Commodity code for a controlled pharmaceutical used in medical and forensic settings. State and local governments procuring under this code are primarily criminal justice and community supervision agencies that require drug-testing supplies and services to support offender monitoring and compliance programs. The work encompasses specimen collection logistics, laboratory testing services using immunoassay and confirmatory methodologies (LC/MS/MS or GC/MS), and multi-panel drug screening with alternative modalities such as oral fluid and hair testing. Issuing bodies include county community supervision and corrections departments, which typically operate through RFP or IFB vehicles and may award to multiple vendors to meet distributed collection-site demand across jurisdictions.

Collin County Community Supervision and Corrections Department posted RFP 2026-327 in September 2026 for offender specimen collection and drug testing services, with an estimated contract value of $600,000 over two years with three optional one-year renewal periods. The scope covers staffing two collection sites in Plano and McKinney with approximately 25,031 annual tests delivered under three pricing models (screening only, confirmation after screening, and screening with automatic confirmation of positives), with laboratory certification required from SAMHSA, Texas Department of Public Safety, or CAP. The evaluation weighed 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 anticipated award date was August 10, 2026, with the contract term beginning September 1, 2026. Texas activity dominates the recent opportunity pool for this code.
