UNSPSC 12352200: Biochemicals

UNSPSC 12352200 Biochemicals is a Class code that covers chemical inputs for municipal water treatment, wastewater management, odor control, and facility maintenance — specifically the procurement of individual chemical compounds and bulk chemical supplies by water utilities, municipalities, and special districts. State and local governments buy sodium hypochlorite, sodium hydroxide, potassium permanganate, liquid calcium nitrate, aluminum chlorohydrate, citric acid, hydrofluosilicic acid, herbicides, fertilizers, and pesticides under this code, typically in bulk quantities delivered on an as-needed or annual-supply basis. Issuing bodies span municipal water and wastewater treatment divisions, county maintenance operations, and regional water reclamation districts; the Town of Groton, Connecticut has posted multiple ITBs for water treatment chemicals, and the City of Flowery Branch, Georgia posted a five-year drinking and wastewater treatment chemical contract, indicating that mid-sized municipalities with dedicated treatment infrastructure are repeat buyers under this code.

Recent activity concentrates in Connecticut, Georgia, California, and Florida. Representative solicitations include the Town of Groton's ITB 26-12 (potassium permanganate, due May 1, 2026), ITB 26-13 (sodium hydroxide, due May 1, 2026), ITB 26-14 (sodium hypochlorite, due May 1, 2026), and ITB 26-15 (liquid calcium nitrate biocide, due May 1, 2026); the City of Flowery Branch's IFB 26-007 for a five-year, multi-chemical supply contract (due April 21, 2026); Pasco County, Florida's IFB-SP-26-074 for herbicides, fertilizers, and pesticides on an as-needed basis (due June 16, 2026); Eastern Municipal Water District's RFP HH3950 for biofilter rehabilitation at the Perris Valley Regional Water Reclamation Facility (due July 24, 2026); and Norwich Public Utilities' ITB 2668 for bulk chemicals (due June 11, 2026). Most procurements use ITB or IFB notice types with firm pricing on a per-unit or per-gallon delivered basis, typically with local vendor preference provisions allowing qualified local vendors within 5 percent of the low bid to match and compete for award. Contract periods range from annual to five years, with as-needed purchase volumes and no guaranteed minimums.
