UNSPSC 51313306 Promethazine sulfoxide is a Commodity code that nominally describes a specific pharmaceutical compound, but the most recent state and local solicitations tagged under it reflect procurement of naloxone and drug deactivation systems for community health and harm-reduction purposes. The code sees activity from county health and community services departments supporting opioid response and public health initiatives. Seminole County, Florida has posted recent solicitations under this code, indicating that regional health authorities are using it to categorize pharmaceutical and medical supply acquisitions even when the specific product differs from the code's formal definition.

Seminole County, Florida represents the primary recent activity under this code. The county issued IFB 60459723LAS in June 2026 (with a response deadline of July 26, 2023) seeking 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 in Sanford. The contract carries a two-year initial term with one-year renewal option, fixed-fee pricing, E-Verify compliance requirements, and potential FEMA funding. Vendors must absorb shipping and delivery costs and maintain workers' compensation, commercial general liability, and professional liability coverage. The mismatch between the code's nominal chemical definition and the actual procurement scope suggests either miscoding by the issuing body or broader state and local classification of pharmaceutical supply categories; either way, the code shows limited relevant activity for vendors in the pharmaceutical compound supply sector.
