UNSPSC 51172138 Methylchromone or tricromyl is a Commodity code showing no recent state and local procurement activity aligned with its nominal chemical scope. The single recent opportunity tagged to this code — Collin County Community Supervision and Corrections Department RFP 2026-327 for offender specimen collection and drug testing services — involves immunoassay screening, LC/MS/MS or GC/MS confirmation, oral fluid and hair testing methodologies, and laboratory certification requirements under SAMHSA, TX DPS, or CAP standards. This is a drug-testing and laboratory certification procurement, not a procurement for methylchromone or tricromyl chemical products. The mismatch between the code's nominal substance and the actual scope of the opportunity signals either a coding error in the source or that this Commodity code does not reflect genuine state and local buying patterns for the chemical itself.

The Collin County RFP, due July 23, 2026 with an estimated contract value of $600,000, calls for operation of two collection sites in Plano and McKinney with approximately 25,031 annual tests across five-panel and six-panel screening methodologies, covering a two-year initial term with three optional one-year renewals. Pricing is required on a per-test basis with three service models (screening only, confirmation after screening, and screening with automatic confirmation), and must include all freight, delivery, insurance, and staffing with no additional surcharges. The evaluation framework weights vendor understanding and firm qualifications at 30 and 25 points respectively, client references at 15 points, and cost at 30 points, with optional Phase 2 demonstrations and interviews adding up to 30 points. Funding derives from Texas Department of Criminal Justice appropriations with annual availability. The anticipated award date is August 10, 2026. No other recent state and local opportunities under this code appear in the source.
