UNSPSC 51312200: Antihistamine or H1 blocker dibenzocycloheptenes

Antihistamine or H1 blocker drugs made from a family of tricyclic hydrocarbons.

UNSPSC 51312200 Antihistamine or H1 blocker dibenzocycloheptenes is a Class code that nominally covers histamine-antagonist pharmaceuticals, but recent state and local procurement activity under this code does not align with that scope. The single recent opportunity tagged to this code—Seminole County, Florida's IFB60459723LAS for naloxone and drug deactivation systems—represents emergency response supplies rather than antihistamine medications. Naloxone is an opioid antagonist used in overdose reversal and is unrelated to H1-receptor blockers or antihistamines, suggesting either a classification mismatch in the county's procurement system or a broader pharmaceutical-supply code that state entities are using to tag mixed medical commodities.

The Seminole County procurement, posted June 30, 2026 with a response deadline of July 26, 2023, sought 1,900 units of naloxone and 800 safe drug deactivation systems annually through quarterly deliveries to the Seminole County Community Health Building in Sanford, Florida. The IFB required electronic bid submission through the county's e-procurement portal, with all shipping and delivery costs included in pricing. The contract carried a two-year initial term with a one-year renewal option and a three-month probationary termination clause. Bidders had to meet E-Verify requirements, drug-free workplace certification, and maintain workers' compensation, commercial general liability, and professional liability insurance. The procurement faced potential FEMA funding and corresponding federal compliance obligations under the Clean Air Act and Federal Water Pollution Control Act. No explicit set-aside designations were named. The code shows minimal recent relevant activity for antihistamine procurement; this appears to be the only recent opportunity, and it represents a category misalignment rather than typical Class-code purchasing patterns.
