UNSPSC 47101606: Corrosion control chemicals

UNSPSC 47101606 Corrosion control chemicals is a Commodity code that encompasses bulk chemical supply and delivery to municipal water and wastewater treatment facilities, with state and local buyers procuring specific formulations—sodium bisulfite, sodium hypochlorite, polyaluminum chloride, magnesium hydroxide, and related treatment products—for hydrogen sulfide control, corrosion mitigation, disinfection, and residual chlorine reduction in potable and reclaimed water systems. Water pollution control facilities and municipal water departments are the dominant issuing bodies, with smaller volumes from county utilities and independent water districts; the recent activity shows repeat procurement from the Town of Killingly (Connecticut), the City of Meriden (Connecticut), the City of Austin (Texas), and the City of Tallahassee (Florida), reflecting both routine annual contracting and rebid cycles when prior vendors do not renew. Solicitations require NSF/ANSI Standard 60 certification for most products, minimum five years of vendor experience in bulk chemical delivery, current HAZMAT endorsements and insurance (general liability typically $1 million per occurrence, pollution liability $1 million per claim), compliance with DOT and EPA hazmat regulations, and delivery within specified operating windows (commonly 7:00 AM to 2:00 PM weekdays). Pricing is quoted on a per-unit basis (per gallon or per pound) with fuel-cost indexing provisions, and emergency delivery with four-hour or 24-hour response times is increasingly required at premium rates.

The code sees heaviest activity in Connecticut, Texas, Florida, and Georgia, with Connecticut municipalities dominating the recent pipeline through June 2026 and Texas cities (Austin, Temple, Phoenix) showing sustained procurement on fixed-term and requirements-contract structures. Representative opportunities include the Town of Killingly's sealed-bid solicitations for sodium hypochlorite (12.5 percent, 14,000 gallons annually, due July 13, 2026), silicon dioxide defoamer (12 barrels annually, due July 13, 2026), and polyaluminum chloride (4,000 gallons annually, due July 13, 2026)—all ITBs requiring three municipal references, on-site training, and 12-month terms with two one-year renewal options; the City of Meriden ITB B026-55 covering seven line items (calcium hypochlorite, caustic soda, aluminum sulfate, sodium permanganate, sodium fluoride, phosphate blend, and ferric chloride) with a June 25, 2026 deadline and Build America Buy America Act sourcing requirements; the City of Austin rebid IFB 2200 BYS1051REBID for 38 percent sodium bisulfite in 330-gallon totes with 5 percent local-business evaluation discount and June 9, 2026 deadline; and the City of Tallahassee IFB-067-26-CPW for magnesium hydroxide slurry (five-year initial term with two optional two-year renewals, June 16, 2026 deadline, requiring NSF/ANSI Standard 60 and rigorous product specifications with field testing and three municipal references). Contracts typically run 12 months with two to four renewal options exercisable at the buyer's discretion, payment terms net 30, and bonding required when estimated annual value exceeds $250,000.
