UNSPSC 12170000: Colorants

A substance that colors materials.

UNSPSC 12170000 Colorants is a Family code that encompasses chemical additives and pigments used across a broad range of state and local operations, though recent solicitations under this code show limited direct alignment with the nominal scope. The recent opportunities posted against this code include janitorial and operational supplies (Hillsborough County), water laboratory testing services (City of Meriden, City of Santa Monica), custodial equipment and supplies (Harlingen Consolidated ISD), copper sulfate for water treatment (Pasco County), herbicides and fertilizers for grounds maintenance (Pasco County), and hazardous waste collection and disposal (City of Lubbock). Of these, only the copper sulfate solicitation from Pasco County maps cleanly to colorants or chemical treatment products; the others appear misclassified. Issuing bodies include county commissions, independent school districts, municipal utilities departments, and special-purpose water authorities, with Florida counties (Hillsborough, Pasco) and Texas jurisdictions (Harlingen ISD, City of Meriden) appearing most frequently in the recent block.

Geographic concentration in recent activity centers on Florida and Texas, with secondary activity in Connecticut and California. Representative solicitations include Pasco County's June 2026 RFQ for large copper sulfate crystals and liquid copper sulfate on an as-needed basis (proposals due June 26, 2026) and Hillsborough County's February 2026 ITB for technical-grade hydrochloric acid (HCL) at 31.5–33.1% concentration for a landfill leachate evaporator facility, estimated at $412,957.50 over three years (bids due March 4, 2026). The code shows actual procurement activity in chemical treatment and maintenance supplies but with significant classification noise—many of the posted opportunities are janitorial and facility services with only tangential relationship to colorants proper. Vendors should verify scope alignment at RFQ or RFP release and focus pursuit efforts on water treatment, landfill operations, and grounds maintenance chemical supply categories where the code sees genuine demand.
