UNSPSC 12163601: Oil production corrosion inhibitors

UNSPSC 12163601 Oil production corrosion inhibitors (Commodity) describes chemical products state and local governments buy for wastewater and water treatment corrosion and odor control, particularly hydrogen sulfide mitigation and residual chlorine reduction at municipal treatment plants and lift stations. Recent solicitations show corrosion inhibitor chemistry being deployed under this code includes magnesium hydroxide slurry for hydrogen sulfide control in sewer collection systems, sodium bisulfite solution for chlorine dechlorination before effluent discharge, and hydrogen peroxide with Peroxide Regenerated Iron Sulfide Control (PRISC) formulations at pump stations and force mains. Water utilities also source treatment chemicals with corrosion-inhibiting properties such as sodium hypochlorite, aluminum sulfate, sodium permanganate, and phosphate blends; while these are nominally classified elsewhere in UNSPSC, they appear in corrosion-inhibitor procurement contexts when deployed specifically to reduce corrosion and extend asset life in aged pipe networks and treatment infrastructure. Issuing bodies include city water departments and authorities (Cartersville, Atlanta-area Gwinnett County, Tallahassee, Griffin, Austin, Temple, Meriden, Lubbock, Macon Water Authority, and Orlando), independent school districts (Dallas ISD), and regional water and wastewater utilities operating hundreds to thousands of miles of sewer main and multiple pump stations serving populations from tens of thousands to hundreds of thousands.

Geographic activity concentrates in the Southeast and South, with recent opportunities posted from Georgia (Cartersville, Gwinnett County, Macon, Griffin), Florida (Tallahassee, Orlando), Texas (Dallas, Lubbock, Temple, Austin), and Connecticut (Meriden). The City of Cartersville Water Department issued an IFB for water treatment chemicals with an October 30, 2026 response date specifying NSF-60-approved aluminum sulfate, liquid lime, chlorine, hydrofluosilicic acid, sodium hypochlorite, and sodium bisulfite across two treatment plants on a renewable one-year term. The City of Austin, Texas solicited bids under IFB 2200 BYS1051REBID for 330-gallon totes of 38% sodium bisulfite solution for as-needed delivery to wastewater treatment plants, with a June 9, 2026 deadline and local-business evaluation discounts of up to 5 percent. The City of Tallahassee issued a firm-fixed-price requirements contract IFB-067-26-CPW for magnesium hydroxide slurry meeting stringent specifications (8.0–7.0 lb/gallon magnesium hydroxide content, ANSI/NSF Standard 60 certification) for a five-year initial term with optional two-year renewals, with bids due June 16, 2026 and local vendor preference available for Leon County–area businesses. Dallas ISD released an RFP for district-wide water treatment services on an as-needed basis with a three-year initial term and two one-year renewal options, with an October 15, 2026 proposal deadline and mandatory SBE evaluation weighting up to 20 percentage points.
