UNSPSC 51241247 Mesulfen or mesulphen is a Commodity code that does not reflect the actual work state and local governments are soliciting under it. The recent opportunities tagged to this code show no mesulfen or mesulphen procurement; instead, they cover liquid aluminum sulfate (alum) for wastewater treatment and medical aid supplies for fire rescue operations — neither of which aligns with the code's chemical scope. The mismatch between the code designation and the solicitations it receives suggests either a data classification error or that this code sees little relevant recent activity in state and local procurement.

The City of Austin posted an IFB on July 27, 2026 for liquid aluminum sulfate delivery to its wastewater treatment facility, with bids due August 25, 2026, and the City of Tampa posted an ITB in April 2026 for medical aid supplies for its Fire Rescue Department with a due date of April 9, 2025. Neither opportunity involves mesulfen or mesulphen as described by the code name. Without additional recent solicitations tagged to this code that match its nominal scope, it is not possible to characterize issuing-body patterns, geographic concentration, or representative demand for the intended commodity itself. Firms should verify code assignments in the source procurement notices before pursuing opportunities listed under this category.
