UNSPSC 47101607: Odor control chemicals

UNSPSC 47101607 Odor control chemicals, a Commodity code, encompasses the supply and delivery of specialty chemicals used by wastewater and drinking water treatment facilities to control hydrogen sulfide odors, manage corrosion in collection systems, and optimize treatment processes. State and local water utilities procure defoamers (silicon dioxide), biocides and ferrous-based additives (ferrous sulfate, ferrous chloride, Bioxide), polymer thickeners and dewatering agents, magnesium hydroxide slurry, and ancillary treatment chemicals including sodium bisulfite, sodium hypochlorite, polyaluminum chloride, and sodium permanganate. Recent activity spans municipalities, county utility commissions, and state water agencies, with the Town of Killingly, Connecticut appearing as a repeat buyer across multiple 2026 solicitations. The work involves bulk delivery (typically 500-gallon to 55-gallon shipment sizes), with strict delivery windows (often 7:00 AM to 2:00 PM), DOT hazmat compliance, and performance testing for alternate products. Bidders must hold five years' minimum experience in bulk chemical delivery, current hazmat endorsements, comprehensive insurance including pollution liability, and NSF/ANSI certification where required for the product supplied.

Geographic activity concentrates in the Southeast and Northeast, with recent solicitations from Connecticut (Killingly, Norwich, Waterford), Georgia (Gwinnett County, Griffin, Flowery Branch), Florida (Tallahassee, Dallas in Texas has also posted), and California (Department of Water Resources). Representative recent opportunities include the Town of Killingly's sealed-bid RFQ for silicon dioxide defoamer (Solicitation 37994, due August 3, 2026) seeking 12 to 55 barrels annually for its water pollution control facility; Sarasota County's five-year IFB 262888RM for odor control mulch bed media refurbishment and replacement at nine public utility vacuum stations (due August 7, 2026); Gwinnett County's competitive sealed-bid procurement for solids dewatering and thickening polymer (BL076-26, due July 30, 2026) requiring bench-scale and full-scale performance testing; and the City of Dallas's 36-month ID/IQ agreement for sewer odor and corrosion control services with ferrous iron salt and bioxide injection across the wastewater system (due June 26, 2026, estimated value $10 million). Most contracts run 12 months initially with optional renewal periods, and award typically goes to the lowest responsible and qualified bidder. Set-asides vary by jurisdiction; Connecticut municipalities have affirmatively committed to disadvantaged business enterprise consideration, while some Southern and Western jurisdictions embed SBE or local preferences where applicable.
