UNSPSC 30121501: Coal tar

UNSPSC 30121501 Coal tar is a Commodity code that covers bituminous materials and asphalt binders used in road construction, pavement maintenance, and infrastructure rehabilitation. State and local governments procure this material primarily through county transportation departments and sanitation districts as part of broader pavement rehabilitation, road resurfacing, and sewer infrastructure repair projects. The material appears in solicitations as a component within larger construction or rehabilitation scopes rather than as a standalone purchase, typically bundled with labor, equipment, and other construction materials needed to complete roadway or utility work.

Santa Clara County has emerged as a recent active buyer, issuing multiple infrastructure rehabilitation bids in 2026 that encompass asphalt and bituminous work. The Central Expressway Pavement Rehabilitation Project Between Bowers Avenue and Scott Boulevard (ITB ITBRDAFY260694, due May 21, 2026) included hot mix asphalt overlay and pavement repairs as core work elements. While the Sanitation District No. 2-3 Structural Defect Repair Project Phase 2 (ITB ITBRDAFY270088, due September 17, 2026) focused on sewer mainline replacement using PVC and HDPE pipe rather than asphalt materials, the prevalence of pavement rehabilitation activity in Santa Clara County signals active procurement of bituminous materials in that jurisdiction. Geographic activity is concentrated in California, specifically the San Francisco Bay Area, based on recent solicitation postings. Bidders should monitor Santa Clara County procurement notices for recurring infrastructure rehabilitation work and coordinate with county transportation and utility departments to stay informed of emerging pavement and road maintenance opportunities.
