About UNSPSC 51363302

UNSPSC 51363302 Methyprylon, a Commodity code, does not reflect the work actually being solicited under this classification in recent state and local procurement. The single recent opportunity tagged to this code—Seminole County, Florida's IFB for naloxone and drug deactivation systems—involves emergency response and public health supplies entirely unrelated to methyprylon, a sedative-hypnotic pharmaceutical. The mismatch suggests either a data-entry error in the opportunity's UNSPSC coding or a fundamental misalignment between the code's pharmaceutical scope and the county's actual procurement need.

Seminole County, Florida posted IFB60459723LAS on June 30, 2026, seeking 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 response deadline was July 26, 2023, with bidders required to submit unit costs, comply with drug-free workplace certification and E-Verify requirements, and maintain workers' compensation, commercial general liability, and professional liability insurance. The contract carried a two-year initial term with a one-year renewal option and included a three-month probationary termination period. No set-aside designations were specified, and the procurement was potentially FEMA-funded. The code shows little relevant recent activity beyond this single misclassified solicitation.
