UNSPSC 51191923 Tretinoin is a Commodity code that in recent state and local procurement activity covers pharmaceutical and chemical supplies for healthcare and municipal operations rather than the dermatological agent the code name suggests. State and local governments soliciting under this code are issuing requests for parenteral products including intravenous and nutrition solutions, chemical supplies for water treatment facilities, and specialized valve components for wastewater systems. The issuing bodies include state departments of corrections, county purchasing offices, and municipal utilities. The Washington State Department of Corrections and the City of Meriden are among the recent buyers, each with distinct supply chains — the DOC procuring parenteral nutrition, intravenous solutions, and controlled substances for eight correctional facilities statewide, and the City of Meriden acquiring sodium bisulfite for water pollution control operations.

Recent activity spans Washington, Florida, and Connecticut. The Washington State Department of Corrections issued an RFQ for parenteral products, services, and equipment with responses due October 7, 2026, anticipating multiple awards across three regions with an initial contract term through June 30, 2030 and set-aside goals for small, minority-owned, women-owned, and veteran-owned businesses. The City of Meriden posted an IFB for sodium bisulfite chemical supply for its Water Pollution Control Facility with a due date of July 29, 2026. Broward County, Florida issued an RFI on September 18, 2026 (responses due September 29, 2026) to determine whether DeZurik/APCO valves and repair services are available from multiple providers or whether sole-source designation to Controls Specialties, Inc. is justified, with technical requirements including SCADA compatibility for remote monitoring in wastewater treatment. The code shows active procurement across different commodity families — parenteral healthcare supplies, industrial chemicals, and specialized equipment — each with distinct delivery, compliance, and technical requirements.
