UNSPSC 12164102: Acid additives

UNSPSC 12164102 Acid additives is a Commodity code covering specialized chemical inputs for municipal water and wastewater treatment operations. State and local governments procure under this code primarily calcium oxide (quicklime), hydrated lime, hydrochloric acid (muriatic acid), citric acid, and related acids used in treatment processes — purchased as bulk liquids, slurries, or powders and typically delivered to water plants, treatment facilities, or reclamation plants on recurring, contract-basis schedules. Recent solicitations show issuing bodies acquiring these materials both through competitive bidding (IFB, ITB, RFQ) and sole-source procurement when OEM compatibility or proprietary service ties apply. The mix of jurisdictions is diverse: Florida cities (Holly Hill, St. Petersburg, Cocoa), Georgia municipalities (Cartersville, Griffin, Valdosta, Gwinnett County), Arizona (Phoenix), Oregon (Clean Water Services district), Connecticut (Meriden), and school districts (Pinellas County, Florida). Water departments and treatment plants dominate as end users, with occasional activity from special districts and school pool maintenance budgets.

Recent representative opportunities include the City of St. Petersburg's IFB for calcium oxide (quicklime) delivery to the COSME Water Treatment Plant at approximately 1,800 dry tons annually with a response date of October 29, 2026; the City of Phoenix's five-year IFB for 31.45% hydrochloric acid and 50% citric acid in bulk totes with questions due October 9, 2025 and proposals due October 16, 2025; the City of Cartersville Water Department's line-item IFB for aluminum sulfate, liquid lime slurry, chlorine, hydrofluosilicic acid, sodium hypochlorite, and sodium bisulfite with bids due October 30, 2026; and the Pinellas County School Board's RFQ for swimming pool chemicals including calcium hypochlorite, muriatic acid, and sodium hypochlorite with a February 11, 2026 deadline. Geographic activity concentrates in Florida and Georgia with secondary presence in the Southwest, Pacific Northwest, and Northeast. NSF 60/61 certification, AWWA standards compliance, and bulk delivery logistics (72-hour lead times, specific facility access requirements) are consistent procurement mandates. Business Enterprise participation requirements appear in several 2026 solicitations; local preference thresholds (5 percent in Cocoa) apply in some jurisdictions. Contract terms typically run one to five years with renewal options. No dollar values are disclosed in the available summaries.
