UNSPSC 12164302: Iron sequestering agent

A specialized additive for preventing the precipitation of metal compounds in oil well formations.

UNSPSC 12164302 Iron sequestering agent is a Commodity code under which state and local governments procure water treatment chemicals, specifically iron-removal and sequestering compounds used in municipal water treatment plants, water reclamation facilities, and public works operations. The recent solicitations indexed under this code reveal a broader pattern of water treatment chemical procurement across multiple Florida municipalities and regional water authorities, though the code's nominal scope (iron sequestering agents) does not align consistently with the chemicals actually being procured in recent competitive opportunities. The issuing bodies are primarily city water departments and municipal utilities (City of St. Petersburg, City of Holly Hill, City of Cocoa, City of Phoenix, City of Valdosta, City of Cartersville, City of Meriden, City of Griffin, City of Jackson, Sarasota County, Gwinnett County, and a water resource recovery district in Oregon), supplemented by school districts procuring pool chemicals for facilities maintenance. Representative recent opportunities include the City of St. Petersburg's IFB-26-344 (October 29, 2026 response date) for calcium oxide delivery to the COSME Water Treatment Plant with estimated annual consumption of 1,800 dry tons at approximately 25-ton bulk orders; the City of Cartersville Water Department's October 30, 2026 ITB seeking aluminum sulfate solution, liquid lime slurry, chlorine, hydrofluosilicic acid, sodium hypochlorite, and sodium bisulfite across two municipal treatment facilities; and Clean Water Services in Oregon's September 30, 2026 ITB for hydrated lime bulk delivery to three water resource recovery facilities.

The geographic spread clusters heavily in Florida (St. Petersburg, Holly Hill, Cocoa, Sarasota County, Jackson, Valdosta) and Georgia (Cartersville, Griffin, Gwinnett County), with activity also in Arizona (City of Phoenix), Oregon (Clean Water Services), and Connecticut (City of Meriden). Recent solicitations consistently require NSF 60 or NSF 60/61 certification for potable water chemicals, AWWA standards compliance, bulk delivery within 72 hours of order, FOB destination pricing with no fuel surcharges, and proof of commercial general liability, pollution liability, and workers' compensation insurance. Sole-source notices posted October 19, 2026 by the City of Holly Hill for proprietary lime slaking systems from Chemco Systems LP and Belt Press separator components from Andritz Separation Inc. illustrate the equipment-maintenance subset of the market, though these represent restricted awards rather than competitive opportunities. The School Board of Pinellas County's RFQ (due February 11, 2026) for swimming pool chemicals across five schools and the City of Tucson's RFP for pool supplies and related services reflect demand from non-municipal water treatment entities. Set-asides and local preferences appear selectively; the City of Cocoa applies a 5% local preference for Brevard County contractors, the City of Phoenix mandates DBE and small business participation reporting under Department of Transportation requirements, and the Pinellas County school district requires E-Verify and background screening compliance. Price adjustment mechanisms typically track the Consumer Price Index, Producer Price Index for Chemicals and Allied Products, or require mutual written agreement, with initial contract terms of one to three years and renewal options extending to five years. No incumbent vendor names appear consistently across multiple solicitations, indicating fragmented supply across jurisdictions.
