UNSPSC 12162303: Cement retarders

UNSPSC 12162303 Cement retarders, a Commodity code, shows minimal recent state and local procurement activity directly aligned with the code's scope. State and local governments typically acquire cement retarders as chemical admixtures for concrete production to extend workability and delay set time in ready-mix concrete operations, particularly in high-temperature environments or where extended placement windows are operationally necessary. However, recent opportunities tagged with this code do not reflect direct procurement of retarder products; instead, the available solicitations emphasize ready-mix concrete delivery, concrete pad construction, and concrete repair services where retarders may be specified as incidental components within larger scopes.

The issuing bodies posting opportunities with or near this code span municipal public works departments, county utilities, and independent school districts across multiple states. Pinal County (Arizona), Volusia County (Florida), Kissimmee Utility Authority (Florida), the City of Olathe (Kansas), and the City of Plant City (Florida) have posted as-needed or annual requirements contracts for ready-mix concrete supply and delivery, and the City of Jackson (Michigan) has solicited continuous delivery services for ready-mix concrete. Notably, Kissimmee Utility Authority conducted two precast concrete pad, sleeve, and post procurements (cancelled and rebid in 2026), suggesting active infrastructure maintenance cycles where retarder chemistry may be embedded in specification but not separately itemized. Geographic activity clusters in Florida and the broader Southeast, with secondary presence in the Midwest and Southwest; most recent postings are from late summer 2026. Representative opportunities include Kissimmee Utility Authority's rebid for precast concrete pads, sleeves, and posts (AR26050JG, bids due August 11, 2026), Volusia County's ready-mix concrete products solicitation (26B74JS, April 23, 2026), and the City of Olathe's ready-mix concrete furnishing and delivery contract (IFB-26-0083, bids due August 21, 2026 with a Johnson County local-vendor preference). Because cement retarders are chemical commodities typically bundled within ready-mix supply agreements rather than solicited as standalone materials, pursuit of this code should focus on ready-mix concrete suppliers and precast concrete manufacturers where retarder specifications are negotiated as part of larger product and service delivery relationships.
