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, a Commodity code, covers a narrow chemical pesticide product that state and local governments buy as part of broader vegetation management and pest control procurement. Recent solicitations show chlorpyrifos appearing as one line item within much larger vegetation management, golf course chemical, mosquito control, and general pest control contracts—rarely as a standalone item. Washington State Department of Enterprise Services' July 2026 RFP (12225RFP) for vegetation management and related products, due August 20, 2026, organizes liquid and dry herbicides alongside aquatic herbicides, adjuvants, surfactants, and ornamental products into a statewide contract vehicle with historical annual spending ranging from $914,419 to $3.87 million and four-year cumulative spending of approximately $7.77 million. Other recent opportunities include the Commonwealth of Kentucky Department of Parks' recurring golf course chemical RFBs (open to six manufacturer-based product groups), Pasco County Florida's as-needed herbicides and pesticides IFB (IFBSP26074, due June 16, 2026), and Hillsborough County's two-year herbicides and insecticides ITB (ITB2600146, due March 6, 2026, estimated at $53,797.50). Issuing bodies span state departments, county purchasing offices, and special districts; state agencies and counties dominate the spend, with historical Washington data showing state agencies at 45.33 percent and counties at 45.11 percent of purchases.

Activity concentrates in Washington, Florida, Kentucky, and Texas, with Washington's vegetation management RFP representing the largest single opportunity in terms of historical spend and geographic scope. Most solicitations are structured as indefinite-quantity or blanket purchase agreements on an as-needed basis, with response cycles of four to six weeks and evaluation favoring low-price bids under EPA registration and state licensing compliance. Bidders must typically hold pesticide dealer licenses, provide product labels and safety data sheets, and comply with state-specific chemical handling and environmental rules. Kentucky's golf course chemical contracts include standing preferences for Kentucky resident bidders and qualified nonprofits at 15 to 20 percent of maximum points. The Washington solicitation adds a five percent cost reduction incentive for certified PCB-free products tested to EPA Method 1668c. Set-asides are infrequent; Pinellas County's mosquito control aerial larvicide ITQ (26-0443-ITQ, April 23, 2026) included local SBE preference on an informal quote basis with a five percent price advantage for non-SBE submitters. Contract terms typically run 12 to 60 months with optional renewals, and pricing generally must remain firm for the first 12 months with CPI-indexed adjustments thereafter or no increases allowed without documented industry-wide justification. The code shows steady but fragmented demand across multiple customer departments within a single jurisdiction rather than concentrated high-volume chlorpyrifos-specific buys.
