UNSPSC 51242011: Salicylic acid/sodium thiosulfate

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 DE500. This VA Drug Class (DE500) classifies this compound as belonging to the group KERATOLYTICS/CAUSTICS, TOPICAL.

UNSPSC 51242011 Salicylic acid/sodium thiosulfate is a Commodity code that in recent state and local procurement shows little activity aligned with its nominal scope. The single clearly on-code opportunity posted under this designation is the City of Austin's IFB 2200 CSH1061, issued July 27, 2026 with bids due August 25, 2026, for liquid aluminum sulfate (alum) — a chemical coagulant used in municipal wastewater treatment to remove soluble phosphorus during the activated sludge process. Austin Water estimated annual demand at 179,200 gallons of unpackaged liquid aluminum sulfate at 47–49% concentration, FOB destination. A second opportunity in the recent-opportunities block — the City of Tampa Fire Rescue Department's ITB 25-P-00157 for medical aid supplies — appears misclassified under this code and does not reflect actual commodity-code activity. The Austin procurement shows state and local governments buying treatment chemicals for wastewater operations under this code when it is used, with specific requirements around NSF approval, AWWA B403 standards compliance, manufacturer or authorized-reseller status, minimum inventory maintenance, and geographic proximity of distribution facilities.

The Austin opportunity represents the primary recent signal for this code in state and local procurement. Austin applied local business and small business preference discounts (5% for local businesses and small businesses separately, potentially combined, on awards up to $50 million) and required bidders to hold commercial general liability and workers' compensation insurance with specified minimum limits, maintain three municipal wastewater treatment references from Texas facilities, and submit certified Certificates of Analysis, Safety Data Sheets, and proof of NSF approval. Unit pricing remained firm for 12 months with price-adjustment requests capped at 25 per line item annually based on the Producer Price Index for chemical product manufacturing. The code shows limited recent volume across state and local jurisdictions; absent additional intelligence beyond the Austin solicitation, this remains a narrow, infrastructure-focused opportunity concentrated in municipal water and wastewater operations.
