UNSPSC 12164201: Acid corrosion inhibitors

UNSPSC 12164201 Acid corrosion inhibitors (Commodity) covers potable and wastewater treatment chemicals that municipal water and wastewater systems deploy to manage corrosion, odor control, and residual chlorine reduction—services state and local governments source under this code with regularity and substantial annual volumes. Recent solicitations by cities and counties show procurement of ortho/polyphosphate corrosion inhibitors, sodium bisulfite solutions, magnesium hydroxide slurry, and related treatment chemicals, with typical annual requirements ranging from 875,000 wet pounds (City of Temple, Texas) to 3,380 gallons (Volusia County, Florida) per facility system. Water and wastewater departments issue these solicitations as Invitations to Bid (ITB) and Invitations for Bid (IFB) with firm-fixed-price requirements contracts spanning one to five years, often with optional renewal periods. Issuing bodies include mid-sized city water systems (Phoenix, Austin, Tallahassee, Temple, Meriden, Griffin, Flowery Branch) and county water utilities (Volusia County, Hillsborough County), typically serving municipal populations of 100,000 to 500,000 residents. NSF Standard 60 certification is a near-universal requirement across municipal potable water treatment solicitations, and AWWA standards are standard across the sector.

Recent activity concentrates in Texas (Austin, Temple, Lubbock), Florida (Tallahassee, Volusia County, Hillsborough County), and scattered mid-Atlantic and Southeast jurisdictions (Connecticut, Georgia). The City of Meriden issued ITB B026-55 (due June 25, 2026) for seven water treatment chemicals including calcium hypochlorite, caustic soda, and sodium permanganate on a one-year contract with two optional renewal years, with Build America Buy America Act compliance mandates on certain line items and Connecticut vendor preference provisions. Volusia County Water Resources & Utilities issued ITB #26-B-60LS (due April 14, 2026) for NSF-certified liquid blended ortho/polyphosphate corrosion inhibitor across six treatment facilities on a three-year initial term with two optional one-year renewals. The City of Austin issued IFB 2200 BYS1051 REBID (due June 9, 2026) and earlier IFB 2200 BYS1051 (due March 12, 2026) for 38 percent sodium bisulfite solution delivery to wastewater treatment plants on a 24-month initial term with up to three optional 12-month renewals, with 5 percent local-business evaluation discounts available for bids under $500,000. Delivery timelines typically require fulfillment within 48 to 72 hours of order placement during standard business hours, with NSF and EPA certifications, product data sheets, and safety documentation mandatory at bid submission.
