UNSPSC 31201616: Liquid adhesives

UNSPSC 31201616 Liquid adhesives is a Commodity code that encompasses concrete sealants and specialized adhesive tapes used by state and local transportation and public facilities agencies. The recent state and local opportunities tagged under this code show divergent scope: the Orange County Transportation Authority's concrete sealant services solicitation reflects the code's core adhesive-products application, while a Dallas County fusion-tape bid and a Sourcewell law-enforcement-equipment RFP appear misaligned with the adhesive-products category and likely represent tagging errors. Issuing bodies pursuing genuine adhesives under this code include transportation authorities and county procurement offices; the concrete sealant work at OCTA represents preventive maintenance on high-traffic transit infrastructure, while smaller-scale industrial adhesive procurements (such as tape for unspecified application) arrive episodically across county systems.

Activity under the code concentrates in California and Texas, with additional multi-state reach through cooperative purchasing vehicles such as Sourcewell. The Orange County Transportation Authority's IFB 250318 for concrete sealant services, posted October 7, 2026 with bids due October 14, 2026 at 11:00 a.m., is the most representative recent opportunity—a $250,000 one-year prevailing-wage contract covering surface preparation and application of penetrating, acrylic, epoxy, and polyurethane sealers across twelve OCTA facilities and sixteen OC Streetcar platforms. Dallas County issued a straightforward IFB (2100758) for fusion tape (1 inch by 0.020 inch by 30 feet) with an October 1, 2026 due date, details otherwise limited. The code shows low recent-activity volume; the concrete-sealant work and tape procurement represent distinct use cases, and the law-enforcement-equipment RFP suggests misclassification rather than adhesive-product demand.
