UNSPSC 12164301: Iron control additives

UNSPSC 12164301 Iron control additives, a Commodity code, covers water treatment chemicals that state and local water utilities and related public bodies procure to support drinking water and wastewater treatment operations. Recent solicitations show this code actually encompasses a broader range of water treatment chemistry than the narrow "iron control" framing alone suggests — municipalities are buying calcium oxide (lime), sodium hypochlorite, hydrochloric acid, liquid lime slurry, aluminum sulfate solution, sodium bisulfite, and related compounds used across treatment plants and water reclamation facilities. Issuing bodies include municipal water departments, city public works agencies, county water utilities, school districts managing pool operations, and regional water resource recovery districts. City of St. Petersburg, City of Phoenix, City of Cocoa, City of Cartersville, City of Griffin, Gwinnett County, Clean Water Services (Oregon), and multiple Florida municipalities appear across recent postings. The work involves supply and delivery of bulk chemical inventories — typically 25 to 1,800 tons annually depending on the facility and use case — with firm NSF or AWWA certification requirements, hazmat compliance, strict delivery windows (often 24 to 72 hours), and multi-year contracts with optional renewals.

Recent activity concentrates in Florida (St. Petersburg, Holly Hill, Cocoa, Sarasota County, Jackson, Valdosta, Tucson, Cartersville, Griffin, and Meriden), with additional recent solicitations from Arizona, Georgia, Connecticut, and Oregon. Representative opportunities include the City of St. Petersburg's IFB-26-344 for calcium oxide delivery to the COSME Water Treatment Plant (bids due October 29, 2026), requiring approximately 1,800 dry tons annually with SBE/MBE/WBE participation mandates; the City of Phoenix's five-year IFB-26-0104 for hydrochloric and citric acid with DBE and small-business participation tracking requirements (proposals due October 16, 2025); the City of Cocoa's ITB B2617COC for liquid sodium hypochlorite with a 5% local preference for Brevard County contractors (bids due September 23, 2026); and the City of Cartersville's solicitation for multiple water treatment chemicals delivered to two facilities on a line-item award basis (bids due October 30, 2026). Sole-source procurements for OEM replacement parts and service from specialized suppliers like Chemco Systems and Andritz Separation also appear in recent Florida notices (Holly Hill, posted October 19, 2026), reflecting the operational lock-in typical of municipal water infrastructure. Bid bonds, performance bonds, insurance thresholds (often $1 million commercial general liability), and compliance documentation are standard across notices. Competition remains open and price-driven across the majority of postings, though local vendor preferences and Business Enterprise participation requirements are active in several jurisdictions.
