UNSPSC 51171505 Simethicone is a Commodity code that captures pharmaceutical ingredient and finished-goods procurement by state and local health agencies, corrections departments, and cooperative purchasing organizations. State and local buyers under this code source both active pharmaceutical ingredients for institutional use and finished over-the-counter digestive aids. The issuing bodies include state health and human services commissions, county corrections and community supervision departments, and multi-state cooperative purchasing alliances administering contracts across participating jurisdictions. Recent solicitations show demand spanning both bulk pharmaceutical procurement through cooperative vehicles and direct specification of simethicone-containing products within broader generic-drug and OTC procurement frameworks.

Geographic activity centers on Texas and the Upper Midwest through multi-state mechanisms. Representative recent opportunities include Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services (due July 23, 2026, estimated value $600,000, term commencing September 1, 2026 for two years with three optional one-year renewals), the Texas Health and Human Services Commission's RFI HHS0017013 on therapeutic pharmacy initiatives and direct-to-manufacturer prescription programs (posted April 3, 2026), and the Minnesota Multistate Cooperative Purchasing Alliance's RFP S1070000015802 for generic multi-source pharmaceuticals and OTC products across participating state and local facilities including Oregon (due March 26, 2026, effective July 1, 2026 for two years with optional extensions).
