UNSPSC 47101609: Microbiocides

UNSPSC 47101609 Microbiocides is a Commodity code covering chemical additives and treatments used in water and wastewater infrastructure to control corrosion, odor, biological growth, and chemical buildup. State and local governments procure microbiocides—including ferrous iron salts, ferrous chloride, sodium hypochlorite, hydrogen peroxide, dewatering polymers, flocculants, and specialized treatment chemicals—for drinking water plants, wastewater treatment facilities, collection systems, cooling towers, and reclaimed-water systems. Recent solicitations show municipalities purchasing both routine operational chemicals and specialized biocides for targeted treatment objectives. Issuing bodies span city water departments, county water authorities, regional water reclamation facilities, school districts, and special-purpose water and sewer districts. Repeat buyers include the City of Waco (Texas), Collier County (Florida), Gwinnett County (Georgia), and Clean Water Services District (Oregon), each soliciting multiple chemical supply contracts. Suppliers typically deliver in bulk totes, drums, cylinders, or intermediate bulk containers with NSF-60 and AWWA certification mandatory for potable-water chemicals and FDA or environmental-compliance documentation standard across applications.

Geographic activity concentrates in the Southeast—Florida, Georgia, North Carolina, and adjacent states—with secondary activity in Texas, the Pacific Northwest, and scattered municipal systems nationwide. Recent representative opportunities include Collier County Procurement Services Division requesting countywide water and wastewater chemicals including sodium hydroxide, polymers, sodium hypochlorite, and ammonia for four treatment plants under ITB 268705, bids due November 13, 2026; Rockland County Sewer District #1 soliciting a solvent-based degreaser for wastewater wet wells under RFB RFBRC2026067, bids due November 12, 2026; the City of Waco issuing multiple RFBs in July 2026 for liquid chlorine, sodium hydroxide, sulfur dioxide, aluminum sulfate, polyaluminum chloride, and dewatering polymers across its water and wastewater treatment plants; and the City of Cocoa requesting liquid sodium hypochlorite for water reclamation under ITB B2617COC with a 5 percent local preference, bids due September 23, 2026. Contracts typically run one to four years with renewal options, price-firm periods of one to two years, and evaluation weighted toward lowest responsive and responsible bidder with occasional local-vendor preferences (Collier County, City of Cocoa, City of Dublin) and SBE participation goals (Dallas ISD, Dallas Water Utilities). NSF and AWWA certifications, E-Verify compliance, performance and payment bonds, and liability insurance are universal requirements; many solicitations require 72-hour to five-business-day delivery windows and prohibit post-award surcharges.
