UNSPSC 51141520 Mephobarbital or methylphenobarbital is a Commodity code that shows a mismatch between its nominal scope—a specific barbiturate pharmaceutical—and recent state and local procurement activity. The single recorded opportunity under this code, Seminole County, Florida's IFB 60459723LAS, solicits naloxone and drug deactivation systems rather than the barbiturate the code nominally describes. The procurement seeks 1,900 units of naloxone and 800 safe drug deactivation systems annually for community health initiatives, with quarterly deliveries to the Seminole County Community Health Building. Vendors must submit bids electronically, include all shipping and delivery costs in their proposals, maintain workers' compensation and commercial general liability insurance, comply with drug-free workplace certification and E-Verify requirements, and accept a three-month probationary termination clause. The contract carries a two-year initial term with an optional one-year renewal and is potentially funded through FEMA, triggering additional compliance obligations under the Clean Air Act and Federal Water Pollution Control Act.

Seminole County, Florida represents the sole recent issuing body identified under this code. The IFB was posted June 30, 2026, with a response deadline of July 26, 2023—a date inconsistency in the source record. The code shows minimal recent procurement activity relevant to its stated pharmaceutical scope, suggesting either sparse actual buying of mephobarbital through state and local channels or chronic miscoding of opportunities under this taxonomy entry. Business development professionals should verify whether this code reflects genuine market demand for the barbiturate or whether state and local agencies are directing related pharmaceutical procurements elsewhere.
