UNSPSC 51172168 Difenoximide hydrochloride is a Commodity code for a pharmaceutical substance, but state and local procurement activity under this code does not reflect direct purchasing of the chemical itself. Instead, Collin County Community Supervision and Corrections Department has posted RFP 2026-327 for offender specimen collection and drug testing services, a program that may employ immunoassay and confirmation testing methodologies as part of routine urinalysis screening but does not solicit difenoximide hydrochloride as a line-item pharmaceutical input. The scope encompasses staffing collection sites in Plano and McKinney, operating an Interactive Voice Response notification system for randomized testing, conducting five-panel and six-panel immunoassay screens with LC/MS/MS or GC/MS confirmation, electronic reporting, and alternative testing methods including oral fluid and hair analysis. Vendors must hold lab certification from SAMHSA, TX DPS, or CAP. The issuing body is a single county-level community corrections department; no repeat buyers appear in the recent opportunities block.

The contract is located in Texas (Collin County, with collection sites in Plano and McKinney). Collin County's RFP 2026-327 with a due date of July 23, 2026 and estimated contract value of $600,000 represents the only recent state or local opportunity tied to this code. The contract term runs two years from September 1, 2026, with three optional one-year renewals, and pricing is structured per-test basis across three service models (screening only, confirmation after screening, and screening with automatic confirmation of positives). The anticipated award date is August 10, 2026. This code shows minimal recent activity and no clear pattern of state or local government procurement of difenoximide hydrochloride as a standalone chemical product.
