UNSPSC 31200000: Adhesives and sealants

UNSPSC 31200000 Adhesives and sealants is a Family code that encompasses protective coating systems, sealant materials, and surface preparation services for infrastructure maintenance — including concrete sealants applied to pavements and transportation facilities, tank coating rehabilitation, specialty tapes and adhesives for industrial and municipal use, and miscellaneous bonding and sealing products purchased by state and local agencies. State and local governments under this code source both ready-to-apply materials (water-based and solvent-based acrylic sealers, epoxy and polyurethane systems, fusion tapes) and full-service application contracts requiring labor, surface preparation, material supply, and waste disposal. Issuing bodies span transit authorities, municipal public works departments, county governments, and special-purpose cooperative purchasing vehicles; transit authorities and cities are the primary recent buyers.

Recent activity clusters in California and Connecticut, with one transaction recorded in Texas. The Orange County Transportation Authority (OCTA) issued IFB 250318 in October 2026 for concrete sealant services at twelve facilities plus sixteen OC Streetcar platforms throughout Orange County, with an estimated contract value of $250,000 and bids due October 14, 2026; the work required California Contractor's License classification C-8, C-61, or D-06 and compliance with South Coast Air Quality Management District VOC requirements. The City of Meriden, Connecticut solicited rehabilitation of the Merimere Water Storage Tank under IFB B02710 in August 2026, encompassing removal of existing coatings, surface preparation, and application of NSF-certified coating systems, with bids due October 7, 2026 and federal Davis-Bacon Act and Build America, Buy America (BABA) requirements in effect. Dallas County, Texas posted an IFB for fusion tape 1 inch by 0.020 inch by 30 feet with a response date of October 1, 2026; the Connecticut municipalities of Torrington and Naugatuck posted broader construction and maintenance supply contracts that include adhesives and sealants among line items. Set-asides or preferences do not appear in the recent posting abstracts except for Connecticut's standard affirmative action encouragement of MBE, WBE, and SBE participation.
