UNSPSC 12161904: Dispersing agents

UNSPSC 12161904 Dispersing agents (Commodity) covers adjuvants, surfactants, and related chemical additives that state and local governments procure alongside herbicides and other vegetation management products for highway maintenance, forestry, and landscaping operations. The code sees activity across state departments of transportation and enterprise services, counties, municipalities, and special districts managing roads, parks, and public lands. State departments dominate as direct purchasers, with counties and municipal jurisdictions as secondary users within cooperative procurement vehicles.

Washington State Department of Enterprise Services posted RFP 12225RFP on July 7, 2026 to establish a statewide contract vehicle for vegetation management products including adjuvants and surfactants, with proposals due August 20, 2026 and contracts anticipated to award October 1, 2026; the department reported four-year cumulative spend of approximately $7.77 million across state agencies (45.33%), counties (45.11%), and special districts (9.64%). Michigan's procurement activity appears tangential to the code's nominal scope—the Michigan Department of Corrections RFP 260000001172 (posted February 12, 2026, proposals due March 2, 2026) procured bulk janitorial chemicals including degreasers and disinfectants for institutional operations rather than dispersing agents for vegetation control, with awards to Arrow Chemical Products, Inc. valued at $2,193,557.10 and Austin Sales Group, Inc. at $928,732.27. Recent activity concentrates in the Pacific Northwest and Midwest, with Washington showing the most relevant current opportunity under the code's nominal scope.
