UNSPSC 51171708 Diphenoxylate is a Commodity code representing pharmaceutical active ingredients and their use in drug testing and criminal justice supervision contexts. State and local governments buy diphenoxylate primarily as a component within broader offender drug screening and testing programs. The work solicited under this code involves substance-testing services delivered by corrections departments, community supervision agencies, and related criminal justice entities that require standardized immunoassay and confirmatory testing (LC/MS/MS or GC/MS) to support probation, pre-trial, and parole monitoring. Issuing bodies are limited to county corrections and supervision departments, typically operating under state criminal justice appropriations or CSCD (Community Supervision and Corrections Department) funding structures rather than municipal or school-district procurement.

Collin County, Texas represents the principal recent activity, having posted RFP 2026-327 on September 25, 2026 for offender specimen collection and drug testing services with a response deadline of July 23, 2026 and an estimated contract value of $600,000 across a two-year base term plus three optional one-year renewals. The scope encompasses staffing two collection sites in Plano and McKinney, immunoassay screening with confirmatory analysis, oral fluid and hair testing methodologies, and approximately 25,031 annual tests. The contract funds from Texas Department of Criminal Justice appropriations and requires vendors to hold SAMHSA, Texas DPS, or CAP lab certification. Pricing is structured on a per-test basis across three service models (screening only, screening with confirmation, or automatic confirmation of positives), with cost representing 30 of 100 evaluation points alongside vendor qualifications, client references, and compliance review criteria. No other recent state or local opportunities appear under this code.
