UNSPSC 12163502: Cement additives

Chemicals and materials are added to a cement slurry to modify the characteristics of the slurry or set cement. Cement additives for oil wells may be broadly categorized as accelerators, retarders, fluid-loss additives, dispersants, extenders, weighting agents, lost circulation additives, and special additives designed for specific operating conditions. Cement additives are commonly available in powder or liquid form, enabling some flexibility in how the cement slurry is prepared.

UNSPSC 12163502 Cement additives is a Commodity code that shows minimal relevant recent state and local procurement activity. Of three recent opportunities tagged under the code, only one—Salt Lake City Corporation's Request for Bid SLCI26071 for surface treatment chip and slurry aggregate—relates substantively to the code's nominal scope; the other two are unrelated (Williamson County's notice of a purchasing department relocation and San Bernardino County's broad parts-and-supplies ITB spanning HVAC components, electrical supplies, plumbing materials, and tools). The Salt Lake City solicitation calls for Grade A chip seal aggregate and Type II slurry seal aggregate, each at approximately 1,250 tons annually, with strict APWA specifications, compatibility testing to WYDOT and AASHTO standards, and delivery to a municipal stockpile location. State and local buyers using this code appear to be primarily public works and facility management departments within individual municipalities and counties, focusing on materials for pavement treatment and surface sealing rather than chemical cement additives per se.

The recent activity that maps to the code is concentrated in the Western states, with Salt Lake City, Utah the only jurisdiction showing a substantive competitive solicitation under the code in the past year. The Salt Lake City RFB, posted January 23, 2026 with a response deadline of February 5, 2026, is a five-year renewable contract with award to the lowest responsive and responsible bidder, pricing on a per-ton basis with firm costs for year one and annual adjustments capped at three percent or the Producer Price Index increase, whichever is lower. No set-asides or vendor restrictions are noted. Given the narrow recent activity and the mismatch between the code's abstract name and actual procurement (materials for surface treatment rather than cement chemical additives), this code warrants monitoring rather than active pursuit unless your firm has specialized offerings in municipal aggregate supply and pavement materials.
