UNSPSC 51241865: Diphenhydramine/zinc oxide

This classification denotes a combination drug defined by the U.S. Department of Veterans Affairs in its (VA's) National Drug File (NDF), which falls under VA Drug Class DE900. This VA Drug Class (DE900) classifies this compound as belonging to the group DERMATOLOGICALS, TOPICAL OTHER.

UNSPSC 51241865 Diphenhydramine/zinc oxide is a Commodity code, but the recent state and local solicitations tagged under it show no activity in that product line. Instead, the posted opportunities involve liquid aluminum sulfate for municipal wastewater treatment and medical aid supplies for fire rescue departments — neither of which are pharmaceutical or topical compounds. The code shows little relevant recent activity, and the mismatch between the nominal scope (a specific pharmaceutical combination) and the actual solicitation subjects suggests the code may be misaligned with how state and local buyers are tagging their purchases, or that recent opportunities have been miscoded.

The two opportunities on record originate from the City of Austin and the City of Tampa. Austin's IFB 2200 CSH1061, due August 25, 2026, seeks 179,200 gallons annually of unpackaged liquid aluminum sulfate at 47–49% concentration for phosphorus removal at its wastewater treatment facility, with local and small business preference discounts of 5% and 3% available on bids under specified thresholds. Tampa's ITB 25-P-00157, originally due April 9, 2025, covers 32 medical and first aid supply items for the Fire Rescue Department with a $100,000 department budget and 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 and $20,000 respectively. Neither opportunity aligns with the code's stated pharmaceutical scope, limiting the utility of this code for vendors in diphenhydramine or zinc oxide product lines.
