UNSPSC 51172332 Acetohydroxamic acid is a Commodity code that captures chemical reagents and testing materials used in laboratory and clinical diagnostic environments. Recent state and local procurement activity shows the code applied to offender drug testing operations, where acetohydroxamic acid and related screening reagents support immunoassay and confirmatory testing workflows. State and local buyers under this code include county supervision and corrections departments operating specimen collection and drug screening programs. The scope of work spans procurement of testing reagents, collection supplies, and associated laboratory materials needed to execute drug screening protocols — typically five-panel, six-panel, and ancillary test formats — along with confirmatory testing methodologies including LC/MS/MS and GC/MS analysis.

Collin County Community Supervision and Corrections Department (Texas) posted RFP 2026-327 on September 25, 2026, for offender specimen collection and drug testing services with a response deadline of July 23, 2026. The county is soliciting services to support approximately 25,031 annual tests across two collection sites in Plano and McKinney, with an estimated contract value of $600,000 over an initial two-year term plus three optional one-year renewal periods. The successful vendor must maintain SAMHSA, Texas DPS, or CAP lab certification and deliver screening, confirmation, and ancillary testing with pricing submitted on a per-test basis under three service models. Award is anticipated August 10, 2026, to the responsible contractor whose proposal represents the best evaluated offer based on vendor understanding, firm qualifications, client references, and cost.
