UNSPSC 51143100: Salicylates

The salts or esters of salicylic acids, or salicylate esters of an organic acid.

UNSPSC 51143100 Salicylates, a Class code, covers chemical treatment products for water and wastewater processing, specifically sourcing liquid aluminum sulfate (alum) and related coagulants used in municipal treatment systems. State and local water utilities and wastewater treatment authorities issue solicitations under this code to procure the specialized chemicals required for phosphorus removal, clarification, and other treatment stages in activated sludge and potable water systems. Issuing bodies are predominantly municipal water departments and standalone water authorities managing treatment facility operations.

Activity appears concentrated in Texas, where the City of Austin's Utilities Department posted IFB 2200 CSH1061 in July 2026 seeking liquid aluminum sulfate at 47%-49% concentration for delivery to its wastewater facility, with bids due August 25, 2026. The Austin solicitation specified 179,200 gallons annually, required NSF approval and AWWA B403 compliance, mandated three current Texas municipal references, and offered local and small business preference discounts (5% and 3% respectively on varying bid thresholds). Price adjustments are permitted annually on the anniversary date, capped at 25% per line item based on Producer Price Index movements. A second opportunity, Tampa Fire Rescue's ITB 25-P-00157 posted in April 2026, appears misaligned with the salicylates code and involves first aid and medical supplies rather than water treatment chemicals, suggesting tagging inconsistency. The salicylates code shows limited recent state and local activity; procurement under this class is episodic and driven by municipal treatment facility budgets and annual chemical replenishment cycles.
