UNSPSC 12165100: Chemicals for enhanced oil recovery

Engineered chemicals, usually as dilute solutions, used to improve or enhance oil recovery from the reservoir

UNSPSC 12165100 Chemicals for enhanced oil recovery is a Class code that state and local governments deploy for water and wastewater treatment chemical procurement, despite the code's nomenclature suggesting petroleum applications. Recent solicitations show municipalities buying chlorine (gas and sodium hypochlorite), aluminum sulfate, ferric chloride, magnesium hydroxide, sodium bisulfite, hydrofluorosilicic acid, potassium permanganate, and ancillary treatment compounds for potable water systems, reclamation facilities, and pollution control plants. Issuing bodies span small cities (Cocoa, Florida; Temple, Texas; Meriden, Connecticut), mid-sized municipalities (Tallahassee, Dallas, Griffin, Georgia), county water authorities (Indian River County, Florida), special districts (Clackamas County Water Environment Services, Oregon), and school districts (Clayton County Public Schools, Georgia; Colquitt County School Nutrition, Georgia). Several jurisdictions appear as repeat buyers—the City of Tallahassee and City of Griffin both posted water treatment chemical bids within the recent window, as did multiple Florida cities. The code also captures industrial facility maintenance chemicals (the Solid Waste Authority of Palm Beach County solicited truck wash soaps; Texas A&M sought aerobic hydrocarbon digesting microbe cultures).

Geographic activity concentrates in Florida (Cocoa, Tallahassee, Indian River County, Solid Waste Authority of Palm Beach County, Meriden), Texas (Edinburg, Temple, Dallas), and Georgia (Griffin, Milledgeville, Dublin, Clayton County), with secondary activity in Arizona (Tolleson), California (Santa Cruz, Milpitas), Connecticut (Manchester), and Oregon (Clackamas County). Representative recent opportunities include the City of Edinburg, Texas IFB #2027-06 (closed September 29, 2026) for an annual 12-month water plant chemical supply covering NSF chlorine, liquid aluminum sulfate, sodium chlorite, and ancillary polymers; the City of Cocoa, Florida ITB B2617COC (closed September 23, 2026) for liquid sodium hypochlorite delivered on 72-hour demand to six facilities with 5 percent local preference; the City of Tallahassee, Florida IFB-067-26-CPW (bids due June 16, 2026) for magnesium hydroxide slurry across a five-year initial term with optional two-year renewals serving approximately 1,000 miles of sewer main; and the City of Griffin, Georgia Invitation to Bid #26-008 (closed May 28, 2026) for 16 water treatment chemicals awarded on a line-item basis with options for four one-year renewals. Most contracts feature firm pricing for 12 months with CPI-capped adjustments thereafter, 48- to 72-hour delivery windows, NSF 60/AWWA certification mandates, and multiple-award structures allowing split orders.
