UNSPSC 51313100: Antihistamine or H1 blocker piperazines

Antihistamine or H1 blocker drugs made from organic compounds composed of a six-membered ring containing two nitrogen atoms at opposite positions (hexa-hydro-pyrazine(s)).

UNSPSC 51313100 Antihistamine or H1 blocker piperazines is a Class code that does not align with state and local procurement activity currently tagged under it. The single recent solicitation in the dataset—Seminole County, Florida's IFB60459723LAS for naloxone and drug deactivation systems—falls outside the code's nominal pharmaceutical scope; naloxone is an opioid antagonist used in overdose reversal, not an antihistamine or H1 blocker. The mismatch suggests either a tagging error in the county's procurement system or a misclassification of the opportunity at posting.

The Seminole County procurement, posted June 30, 2026 with an IFB notice type and a response deadline of July 26, 2023 (a date that predates the post date and appears to be a data error), sought 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries to the Seminole County Community Health Building in Sanford, Florida. The contract carried a two-year initial term with a one-year renewal option, required E-Verify compliance and drug-free workplace certification, and included potential FEMA funding with associated federal compliance obligations. This code shows little relevant recent activity and the single opportunity represents a clear scope mismatch rather than authentic demand under the antihistamine classification.
