European Medicines Agency schedules Simethicone in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Indices SUB45207 and SUB04403MIG. Simethicone bears US NLM identifiers UMLS ID C0037138 and NCI Concept Code C29453. SMILES: CO[Si](C)(C)O[Si](C)(C)C.O=[Si]=O.

UNSPSC 51171505 Simethicone is a Commodity code for a pharmaceutical ingredient with minimal relevance to the recent state and local procurement activity tagged under it. The single posted opportunity — Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services — concerns laboratory testing infrastructure, staffing, and confirmatory analysis methodologies (immunoassay screening with LC/MS/MS or GC/MS confirmation, oral fluid and hair testing) rather than procurement of simethicone itself or any pharmaceutical product. The scope encompasses operating two collection sites in Plano and McKinney, running an Interactive Voice Response system for randomized testing notifications, and providing electronic result reporting, with annual testing demand of approximately 25,031 tests across five-panel and six-panel screens and ancillary testing.

The Collin County RFP due July 23, 2026 carries an estimated contract value of $600,000 over a two-year term with three optional one-year renewal periods (five years maximum) and requires the successful vendor to maintain lab certification from SAMHSA, TX DPS, or CAP. Pricing is submitted on a per-test basis with three service models (screening only, confirmation after screening, or screening with automatic confirmation of positives), and all costs must include freight, delivery, insurance, and staffing with no additional surcharges. Evaluation weighs vendor understanding (30 points), firm qualifications (25 points), client references (15 points), and cost (30 points), with optional Phase 2 demonstrations and interviews worth up to 30 additional points. The code shows no other recent state and local activity, indicating this Commodity classification does not map to active procurement demand in the state and local market.
