UNSPSC 10191522: Chlorpyrifos

Chlorpyrifos is an organophosphate insecticide, acaricide and miticide used primarily to control foliage and soil-borne insect pests. In August 2021, EPA released a final rule revoking all "tolerances" for chlorpyrifos, which establish an amount of a pesticide that is allowed on food.

UNSPSC 10191522 Chlorpyrifos is a Commodity code covering a narrow pesticide product family with limited documented recent state and local activity. The single clear match in recent solicitations is the Galveston County Mosquito Control Department's procurement of Permethrin 31% & 66% Piperonyl Butoxide (posted May 19, 2026), which represents chemical pest management supply—not chlorpyrifos specifically but the same active-ingredient procurement category. Beyond that one relevant record, the remaining opportunities tagged to this code span aerial mosquito control services, herbicide spraying, vegetation management supply contracts, golf course chemical masters agreements, and facility pest control services—all distinctly different from a single-ingredient pesticide commodity. The mismatch suggests either tagging inconsistency in the state and local procurement platforms or that chlorpyrifos appears as a line item within broader pest management or vegetation control solicitations rather than as a standalone contract driver.

State and local governments purchasing under this code appear to be primarily county mosquito control and parks departments, along with city and county maintenance divisions managing turf, vegetation, and structural pest control. Recent activity appears most concentrated in Florida (Valencia College statewide pest control across eleven campuses in an ITB; Pasco County herbicide and pesticide on an as-needed basis; Pinellas County aerial larvicide application; Orange County aerial mosquito control; Galveston County permethrin supply), with secondary activity in Texas (City of McKinney pest control ITB; Hillsborough County herbicide spraying and planting for three years at an estimated $544,532.50), Arizona (City of Tucson pest and termite control RFP across three service groups), Kentucky (Department of Parks golf course chemical master agreements), Washington (Department of Enterprise Services statewide vegetation management and related products RFP with four-year cumulative spending of approximately $7.77 million), and Georgia (DeKalb County reconstruction project). No recent solicitation is exclusively or primarily focused on chlorpyrifos procurement as a named product, and activity under the code does not support material near-term pursuit signals.
