UNSPSC 12161904: Dispersing agents

UNSPSC 12161904 Dispersing agents is a Commodity code under which state and local governments procure chemical products that break down, suspend, or separate solid material in liquid processes—primarily polymers and adjuvants used in wastewater treatment, vegetation management, and institutional maintenance. Recent solicitations show state and local buyers acquiring cationic liquid polymers for sludge dewatering, herbicide adjuvants and surfactants for vegetation control, and bulk chemicals including degreasers and disinfectants for correctional and municipal operations. Issuing bodies span state departments of enterprise services and corrections, county utilities and public works, and city procurement offices, reflecting the distributed nature of chemical usage across infrastructure, environmental, and facility management.

Geographic activity appears concentrated in the Pacific Northwest and Great Lakes region, with recent solicitations from Washington State Department of Enterprise Services, Volusia County and the City of Daytona Beach in Florida, and the Michigan Department of Corrections. The Washington State Department of Enterprise Services RFP (12225RFP), due August 20, 2026, establishes a statewide contract for vegetation management products including adjuvants and surfactants, with anticipated spend of $914,419 to $3.87 million annually and primary purchasers across state agencies (45.33%), counties (45.11%), and special districts (9.64%). Volusia County, Florida issued IFB 2363ITB for cationic liquid polymer for wastewater sludge dewatering with a response deadline of October 26, 2026, submitted through the City of Daytona Beach's OpenGov platform; pre-qualification sheets and laboratory testing requirements indicate performance validation is a qualification threshold. The Michigan Department of Corrections procured bulk chemicals including degreasers and disinfectants through Michigan State Industries, awarding approximately $3.12 million across three-year initial terms to two vendors, with safety data sheet approval by facility fire and environmental health personnel as a compliance requirement.
