UNSPSC 31211800: Paint solvents and thinners

UNSPSC 31211800 Paint solvents and thinners is a Class code covering paint-related chemicals and preparation materials that state and local governments procure for facility maintenance, transit operations, and general fleet upkeep. Recent solicitations show state and local buyers requesting mineral spirits, paint reducers, epoxy primers, and related coating preparation supplies alongside broader maintenance and painting inventories. School districts, county sheriffs' offices, transit authorities, and public works departments are the primary issuing bodies, with San Antonio Independent School District (SAISD) appearing repeatedly across multiple as-needed maintenance RFPs issued since February 2026. The work spans routine maintenance material procurement (mineral spirits for departmental use), specialized marine and automotive painting supply contracts (epoxy primers, reducers, brushes, masking materials), and transit-fleet paint systems (OEM-approved bus coatings and preparation materials).

Activity clusters in California and Texas. The County of Orange, California (Public Works and Sheriff-Coroner) has issued two competitive IFBs since February 2026 covering traffic and graffiti paints, thermoplastic markings, and marine hardware with painting supplies, with the public works contract carrying a $1.375 million not-to-exceed value over five years and a February 13, 2026 bid deadline. Hillsborough County, Florida solicited mineral spirits in June 2026 with a July 6 due date and no small local business enterprise set-aside. The City of Charlotte issued an RFP for bus paint and related materials with a July 17, 2026 proposal deadline. SAISD has posted continuous, open-ended RFPs for general maintenance services (including painting supplies) multiple times since February 2026, with versions due March 31, May 15, June 15, July 15, and August 15, 2026, structured as multiple-award contracts with no guaranteed minimum and contingent on district funding availability. Orange County offers five-percent local small business and disabled veteran business enterprise price preferences on eligible paint and coatings procurements.
