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, a Commodity code, sees state and local procurement activity dominated by antifreeze and related maintenance fluids rather than cement-specific additives. The City of Detroit's recent RFQ for ethylene glycol antifreeze in bulk and 55-gallon drums illustrates the practical scope: state and local governments under this code are buying fully formulated, inhibited antifreeze for vehicle fleet maintenance, with specifications for both concentrate and premixed formulations, delivery within three business days, and hazmat transportation and liability compliance from vendors. The City of Detroit RFQ also required samples with spectrochemical analysis and infrared scan reports prior to award. A broad San Bernardino County ITB for facility maintenance parts and supplies that includes chemicals among over 500 line items suggests the code captures some procurement of maintenance fluids and related supplies across county operations, though that opportunity does not detail cement-additive-specific content. Issuing bodies include city and county procurement offices managing fleet and facilities operations; no school districts, transit authorities, or state departments appear in the recent record.

Recent activity concentrates in Michigan and California. The City of Detroit's antifreeze RFQ (due October 9, 2026) targets an estimated annual volume of approximately 24,000 gallons across concentrate and premixed formulations, with awards subject to Detroit-based business equalization credits of one to five percent and potential small-business set-asides if three or more certified firms compete. San Bernardino County's ITB 6391 for parts and supplies (due June 19, 2026) applied a 5 percent local vendor preference for suppliers headquartered within County boundaries. The code shows limited recent opportunities and appears misaligned with its nominal scope — cement additives per se do not surface in the posted records, and the actual buying pattern reflects automotive and facilities maintenance fluids rather than concrete-related chemistry.
