UNSPSC 51191528 Althiazide or altizide is a Commodity code that in practice captures state and local procurement of pharmaceutical and chemical products for healthcare, correctional, and water-treatment operations. Recent state and local solicitations show the code being applied to parenteral pharmaceutical products (intravenous solutions, total parenteral nutrition, and controlled substances for correctional healthcare), industrial chemicals for water treatment (sodium bisulfite), and specialized valve components for wastewater infrastructure. Issuing bodies include state departments (Department of Corrections), county purchasing offices (Broward County), and municipal water utilities (City of Meriden). The scope reflects a divergence between the code's narrow pharmaceutical name and its application across healthcare delivery, correctional services, and municipal water-treatment operations.

Recent activity concentrates in Florida and Washington state. The Washington State Department of Corrections issued an RFQ for parenteral products and services on September 8, 2026, with responses due October 7, 2026, soliciting IV solutions, total parenteral nutrition (TPN and PPN), and controlled substances for eight correctional facilities across three regions, with contract award anticipated November 26, 2026 through June 30, 2030 and optional discretionary extension; DOC encourages participation from small businesses (25%), minority-owned businesses (10%), women-owned businesses (6%), and veteran-owned businesses (5%), and requires fixed pricing for the initial two-year term. Broward County, Florida issued a Request for Information on September 18, 2026 (responses due September 29, 2026) regarding DeZurik/APCO valves, parts, and repair services for wastewater treatment compliance, issued to determine sole-source justification prior to potential award to Controls Specialties, Inc. The City of Meriden, Connecticut solicited bids for sodium bisulfite chemical supply for water-treatment operations under solicitation B027-15 with a due date of July 29, 2026.
