UNSPSC 12161906: Wetting agents

UNSPSC 12161906 Wetting agents (Commodity) covers surfactants, adjuvants, and related chemical additives that state and local governments procure for vegetation management, landscape maintenance, and institutional chemical operations. Recent solicitations show wetting agents being bought as components of broader herbicide and chemical product contracts rather than as standalone items, bundled with liquid and dry herbicides, aquatic herbicides, and ornamental products for highway, park, and municipal grounds maintenance. State agencies, counties, municipalities, and special-purpose districts issue solicitations under this code; Washington State Department of Enterprise Services and the Michigan Department of Corrections represent significant institutional buyers conducting competitive procurements that span multiple jurisdictions or service areas.

The most recent activity concentrates in Washington, Arizona, Michigan, and Connecticut. Washington State Department of Enterprise Services posted RFP 12225RFP on July 7, 2026 (due August 20, 2026) to establish a statewide contract vehicle for vegetation management products including surfactants and adjuvants, with historical annual spending ranging from $914,419 to $3.87 million and primary purchasers split between state agencies (45.33%), counties (45.11%), and special districts (9.64%); the solicitation anticipates up to four Main Awards and up to one Reserved Award (restricted to Washington Small Business and/or Certified Veteran-Owned Business) per contract category. The City of Peoria, Arizona issued RFQ P260071 (due July 3, 2026) for fertilizer and chemical products including potential wetting agents for park and right-of-way maintenance. Michigan Department of Corrections through Michigan State Industries solicited bulk chemicals via RFP 260000001172 (due March 2, 2026) encompassing nineteen chemical products with a recommended total award value of approximately $3.12 million across three-year and two-year renewal periods.
