UNSPSC 12161703: Other buffers

UNSPSC 12161703 Other buffers is a Commodity code under which state and local governments procure water treatment, pool, and wastewater chemicals—primarily alkaline and acidic compounds used to adjust pH, sanitize, and support coagulation in municipal treatment systems. The scope spans calcium hypochlorite, sodium hydroxide (caustic soda), hydrochloric acid (muriatic acid), aluminum sulfate, sodium permanganate, sodium fluoride, phosphate blends, sodium hypochlorite, potassium permanganate, soda ash, and specialized acid products for landfill leachate treatment. Issuing bodies include municipal water and wastewater utilities, county environmental departments, city public works offices, school districts with aquatic facilities, and county parks and recreation departments. Cities of Meriden, Jackson, Griffin, Salem, St. Petersburg, Lubbock, Holly Hill, and Orlando; Sarasota County; Hillsborough County; Greenville County; and the Pinellas County and School Board of Pinellas County School District appear as recent solicitors, with water departments as the dominant buyer category.

Activity concentrates in the Southeast (Florida, Georgia, South Carolina, Connecticut) and extends to Texas, Oregon, and beyond. Representative recent opportunities include the City of Meriden ITB B026-55 for water treatment chemicals (due June 25, 2026), covering seven line items with NSF and AWWA certification requirements and Build America Buy America Act compliance for select products; the City of Griffin Invitation to Bid 26-008 for FY2027 water treatment chemicals (due May 28, 2026), seeking sixteen chemical products with delivery to six facilities and line-item award structure; Sarasota County Quick Quote 2026QQ704 for industrial-grade muriatic acid (due May 12, 2026), specifying twelve 55-gallon drums for membrane cleaning; and Greenville County RFP #26100 for pool chemicals and maintenance services (due May 5, 2026), bundling chemical supply with routine and emergency maintenance across twelve county aquatic facilities. Contracts typically run one year with two to four optional renewal periods, with NSF/ANSI/CAN 60 certification and AWWA standards nearly universal for potable-water applications. Award methodology favors lowest responsible bidder on line-item or aggregate basis, with firm pricing for initial terms and CPI-indexed escalation permitted thereafter.
