UNSPSC 12164001: Registered microbiocides

UNSPSC 12164001 Registered microbiocides (Commodity) encompasses liquid and solid chemical additives—particularly those registered as antimicrobial agents—that state and local water and wastewater utilities procure for treatment, odor control, corrosion mitigation, and system maintenance. Recent solicitations show purchasing focused on sodium hypochlorite, chlorine, sodium bisulfite, ferrous salts, and specialty polymers for dewatering and thickening applications across municipal water treatment plants, wastewater reclamation facilities, and collection systems. The code sees activity primarily from county water authorities, city water departments, and municipal utilities; repeat buyers include Collier County (Florida), Gwinnett County (Georgia), and the City of Waco (Texas), each issuing multiple RFBs and ITBs for chemical supply. Geographic concentration is heaviest in the Southeast (Georgia, Florida, Texas, and Arizona) and Pacific regions (California, Oregon), with secondary activity in the Midwest and Northeast.

Representative recent solicitations include Collier County Board of County Commissioners requesting countywide water treatment chemicals under ITB 268705 (response due November 13, 2026) for three water treatment facilities and six aquatic recreation facilities, with estimated annual spend of approximately $4 million across 29 line items including ammonia, chlorine, sulfuric acid, sodium hypochlorite, and polymers; the City of Waco issuing thirteen separate RFBs between July 30 and August 21, 2026 for liquid oxygen, sodium hydroxide, liquid chlorine, cationic dewatering polymers, and liquid aluminum sulfate; and Clean Water Services District (Oregon) requesting bids on sodium hydroxide solution and sodium bisulfite solution under ITB format with response dates of September 30, 2026. Rockland County Sewer District #1 (New York) posted a solvent-based degreaser bid (RFBRC2026067, due November 12, 2026) with pre-approved product samples and alternate formulation evaluation requirements. Local-vendor preferences appear in Collier County (5% within lowest), City of Cocoa (5% for Brevard County), and City of DeLand (best and final offers for local bidders within 5% of lowest). All solicitations mandate AWWA and NSF 60/61 certifications, compliance with safety data sheet submission requirements, and delivery within two to five business days of order placement. Contract terms typically run twelve months with annual renewal options; pricing remains firm for the initial term with adjustments permitted annually on anniversary dates subject to cost-index documentation or procurement director approval.
