UNSPSC 51393004 Piquizil hydrochloride is a Commodity code that nominally covers a specific pharmaceutical agent, but recent state and local procurement activity under this code shows a significant mismatch with its abstract scope. The sole identified opportunity—Seminole County, Florida's IFB for naloxone and drug deactivation systems—involves naloxone (an opioid antagonist used to reverse opioid overdose) and deactivation equipment, not piquizil hydrochloride. This suggests either a tagging error in the county's procurement system or a misalignment between the code's intended pharmaceutical scope and how the jurisdiction actually applied it. State and local governments soliciting under this code are limited in the visible record to county-level public health departments seeking emergency-response pharmaceuticals and harm-reduction equipment, though the single opportunity does not support broader issuing-body characterization.

Seminole County, Florida represents the only recent state and local activity identified under this Commodity code. In June 2026, Seminole County issued IFB 60459723LAS seeking annual procurement of 1,900 units of naloxone and 800 safe drug deactivation systems, with quarterly deliveries to the Seminole County Community Health Building in Sanford. The bid deadline was July 26, 2023, and the contract included a two-year initial term with an optional one-year renewal, fixed-fee pricing, E-Verify compliance, drug-free workplace certification, and federal compliance requirements tied to potential FEMA funding. Vendors were required to submit electronic bids including all shipping and delivery costs. The procurement shows no explicit set-aside designations for disadvantaged enterprises. The sparse activity level under this code suggests either low demand for piquizil hydrochloride specifically within state and local procurement, or systematic miscoding in jurisdictional procurement systems.
