UNSPSC 51431709 Diltiazem malate (Commodity) encompasses emergency and critical-care injectable medications procured by state and local health and public-safety agencies, specifically diltiazem formulations used in advanced life support protocols by fire rescue and emergency medical services. State and local purchasing offices solicit these medications through sealed-bid procurements and IFBs, requiring vendors to meet strict expiration-date thresholds, rapid delivery windows, product warranties, and compliance with OSHA and federal accessibility standards. Issuing bodies include city fire departments and municipal health procurement offices managing inventory for paramedic and emergency care units.

The City of Tampa's Purchasing Department posted an IFB (26P00188) on April 24, 2026, for Advanced Life Support Medications to supply Tampa Fire Rescue in Hillsborough County, Florida, requesting 1,020 units of Diltiazem 25mg vials alongside three related medications (Labetalol, Epinephrine, and Adenosine), with a response deadline of April 8, 2026 and an estimated contract value of $40,000. The solicitation included a 5 percent bid discount for Small Local Business Enterprise (SLBE) participation (not to exceed $10,000), required medications to maintain nine months or more shelf life from acceptance, mandated delivery within ten calendar days of order, and specified a one-year initial term with options for two additional one-year renewals plus unilateral city extension rights for up to three 30-day periods. Based on recent activity, Florida municipalities remain primary buyers of this commodity, though the narrow sample limits geographic characterization beyond Tampa Bay.
