NIGP 63090: Thinners (Reducers): Alcohols, Aromatic Solvents, Esters, Ketones, Mineral Spirits, Turpentine, V M and P Naphtha, etc.

NIGP 63090 Thinners (Reducers): Alcohols, Aromatic Solvents, Esters, Ketones, Mineral Spirits, Turpentine, V M And P Naphtha, Etc. is an Item code under which state and local governments procure paint thinners, reducers, and related solvents for fleet maintenance, facility upkeep, and general maintenance operations. Recent activity shows school districts, counties, and transit authorities sourcing mineral spirits, epoxy primers, paint reducers, and finishing materials for building maintenance and vehicle refurbishment on both standalone and as-needed bases within broader maintenance service contracts. San Antonio Independent School District has posted multiple continuous, open-ended RFPs for general maintenance services, parts, repairs, supplies, and equipment—encompassing thinners and reducers among broader maintenance inventory—with repeated solicitations cycling through the market on a rolling basis (four separate RFP iterations from May through October 2026, with response dates ranging from mid-June to mid-October).

Activity concentrates in Texas and California. Hillsborough County issued an IFQ for mineral spirits in June 2026 (due July 6, 2026) with no SLBE set-aside. The County of Orange, Sheriff-Coroner, released an IFB for marine hardware and painting supplies in March 2026 (due April 16, 2026) covering epoxy primers, reducers, brushes, and masking materials across 197 line items, structured as a firm fixed-fee contract with a three-year initial term plus two optional one-year renewals, offering five percent price evaluation preferences to Certified County of Orange Local Small Business and DVBE bidders. The City of Charlotte solicited bus paint and coatings for transit fleet maintenance in June 2026 (due July 17, 2026), requiring OEM-approved products with comprehensive documentation. Issuing bodies include independent school districts, county sheriffs' offices, transit authorities, and general county purchasing departments; repeat activity from San Antonio ISD suggests ongoing demand through continuous procurement vehicles on an as-needed model.
