UNSPSC 51151641 Fentonium is a Commodity code that does not match the work actually being solicited under it in recent state and local procurement activity. The single recent opportunity on file — Seminole County, Florida's IFB 60459723LAS, posted June 30, 2026 — calls for the purchase of naloxone and safe drug deactivation systems, not fentonium. The county seeks 1,900 units of naloxone and 800 safe drug deactivation systems annually through competitive bidding, with quarterly deliveries to the Seminole County Community Health Building. The mismatch between the code's nominal scope and the actual procurement suggests either a classification error in the county's notice or a code definition that does not reflect current buying patterns in state and local health and emergency-response supply chains.

The sourced opportunity provides minimal insight into issuing-body mix, geographic concentration, or market activity under this code. Seminole County's procurement is the only recent opportunity documented, making it impossible to characterize the breadth of jurisdictions engaging under this code or whether the category sees meaningful activity elsewhere. The response deadline for the Seminole County IFB was July 26, 2023 — a date that has passed — and no subsequent opportunities appear in the current record. The code shows little relevant recent activity; business development professionals should verify current code assignments and recent procurement patterns before allocating pursuit resources to this category.
