UNSPSC 51242000: Combination keratolytics/caustics

This classification denotes combination drugs and preparations that a) soften, separate, and cause desquamation of the cornified epithelium layer of skin, or KERATOLYTICS, and so named because they contain keratin, constituient skin proteins; or b) combination drugs and preparations that constitute alkaline chemicals that destroy soft body tissues resulting in a deep, penetrating type of burn, called CAUSTICS, so named because they cause burns. collodion, Typical combination keratolytic/caustic constituents are lactic acid, phenol, podophyllin, propane, resorcinol, salicylic acid, sodium thiosulfate, sulfur, sulfurated potash, urea, and zinc oxide.

UNSPSC 51242000 Combination keratolytics/caustics, a Class code, does not align with the recent state and local solicitations tagged under it. The City of Austin's IFB for liquid aluminum sulfate (alum) used in wastewater treatment phosphorus removal and the City of Tampa's ITB for medical aid supplies (antiseptic sprays, hydrogen peroxide, bandages, first aid kits) represent chemical water treatment and medical supplies respectively—neither falls within the keratolytic or caustic scope the code nominally describes. The mismatch suggests either misclassification in the issuing bodies' tagging systems or a divergence between the code's intended use and state and local procurement practice.

The recent activity spans two municipalities—Austin and Tampa—with no geographic concentration or repeat issuing bodies evident in the opportunities block. The Austin Water solicitation (IFB 2200CSH1061, due August 25, 2026) specifies 179,200 gallons of 47%-49% concentration unpackaged liquid aluminum sulfate delivered annually, with local and small business preference discounts available. The Tampa Fire Rescue solicitation (ITB 25-P-00157, originally due April 9, 2025) covered 32 medical and first aid supply line items with a $100,000 total department budget and set-asides for City-certified Small Local Business Enterprises and Underutilized Woman and Minority Owned Business Enterprises. Absent clearer alignment between the code definition and the goods actually being procured, this code merits review for proper classification before pursuing opportunities under it.
