UNSPSC 12161903: Foaming agents

UNSPSC 12161903 Foaming agents is a Commodity code covering chemical additives and treatment compounds used by state and local governments for wastewater treatment, vegetation management, and institutional maintenance operations. Recent solicitations show state and local buyers procuring cationic polymers for sludge dewatering, herbicides and surfactants for vegetation control, and bulk chemicals for correctional facility operations—a scope that extends well beyond foaming agents narrowly construed to encompass a broader family of process chemicals and treatment additives. State departments, counties, and special-purpose districts issue solicitations under this code, with the Washington State Department of Enterprise Services and Michigan Department of Corrections appearing as significant recent purchasers establishing multi-year statewide or system-wide contracts.

Activity is geographically distributed across Florida, Washington, and Michigan based on recent postings. The Washington State Department of Enterprise Services issued a statewide RFP for Vegetation Management & Related Products on July 7, 2026, with proposals due August 20, 2026, establishing a contract vehicle for herbicides, aquatic herbicides, adjuvants, and surfactants serving state agencies, counties, and municipalities across Washington—historically spending $914,419 to $3.87 million annually and approximately $7.77 million over four years. Volusia County, Florida solicited cationic liquid polymer for wastewater sludge dewatering via ITB 2363ITB (posted August 11, 2026, with bids due October 26, 2026), requiring bidders to register and submit through the City of Daytona Beach's OpenGov platform with pre-qualification testing documentation. The Michigan Department of Corrections awarded bulk chemical contracts totaling approximately $3.12 million over three years to Arrow Chemical Products, Inc. and Austin Sales Group, Inc. for institutional maintenance chemicals including disinfectants, degreasers, and detergents.
