UNSPSC 51241248 Methoxsalen or xanthotoxin is a Commodity code, but the recent state and local opportunities tagged under it do not align with its pharmaceutical scope. The City of Tampa Fire Rescue Department posted ITB 25P00157 in April 2026 for Medical Aid Supplies — a broad procurement spanning antiseptic sprays, hydrogen peroxide, aspirin, pain relievers, bandages, first aid kits, and emergency blankets with an estimated annual budget of $100,000. The solicitation targets one-year awards with two optional one-year renewals and includes set-aside provisions for City-certified Small Local Business Enterprises and Underutilized Woman and Minority Owned Business Enterprises, offering bid discounts up to $10,000 for SLBEs and $20,000 for U-WMBEs. The code shows limited relevant recent activity; the single posted opportunity does not reflect the pharmaceutical or dermatological products the code nominally describes.

The Tampa Fire Rescue procurement is the only recent state and local opportunity under this code in the source. Geographic concentration cannot be assessed from a single jurisdiction. The mismatch between the code's intended scope — specialized pharmaceuticals for photochemotherapy — and the actual procurement activity suggests either miscoding by the issuing body or misalignment between the code taxonomy and current state and local medical-supply procurement patterns. Firms pursuing work under this code should verify directly with issuing procurement offices that opportunities are correctly tagged before investing in qualification or bid preparation.
