NIGP 775: Salt (Sodium Chloride) (see Class 393 for Table Salt)

NIGP 775 Salt (Sodium Chloride) is a Class code under which state and local governments procure ice-control materials—primarily calcium chloride and rock salt in liquid, granular, and pelletized forms—for winter road and facility maintenance. Recent solicitations show municipalities and school districts buying de-icing compounds for street maintenance, parking areas, sidewalks, and school grounds, with specifications tied to purity, gradation, moisture content, anti-caking treatment, and safety claims for vegetation and concrete compatibility. Issuing bodies span city public works departments (Detroit, Wichita, Lubbock), school districts operating cooperative purchasing agreements (Huron Valley Schools through CoPro+), and county agencies. The code also captures vendor-supplied ice-melt products marketed through statewide cooperative frameworks. Scope varies between direct-delivery contracts with per-unit pricing and framework agreements establishing prequalified vendor pools for as-needed ordering, with typical contract terms of one to three years and automatic renewal options.

Recent activity concentrates in the Midwest and South. The City of Detroit's RFQ (due October 14, 2026) seeks 300,000 gallons of liquid calcium chloride for ice control on city streets, with vendor-site loading or delivery to DPW storage; bidders must demonstrate three years' experience and maintain a facility within twenty miles of Detroit with 24/7 accessibility, while Detroit's equalization credit policy applies pricing adjustments of 1% to 5% for Detroit-based vendors. Huron Valley Schools, through the CoPro+ cooperative purchasing vehicle managed by the Public Procurement Institute of Michigan, has issued multiple RFQs (most recent due September 28, 2026) for ice-melt supply to Michigan school districts and counties, requiring three customer references and three-year statewide cooperative terms with optional renewals; award anticipated October 2026. The City of Wichita issued separate procurements for rock salt (due May 29, 2026), salt-and-sand mixtures (due August 7, 2026), and calcium chloride pellets (due May 15, 2026), all for Public Works operations. The City of Lubbock, Texas solicited granular road maintenance salt under ITB (due June 10, 2026) with local vendor preference under Texas Local Government Code 271.9051. Pricing structures typically quote F.O.B. delivered with firm rates guaranteed 60–90 days from contract effective date, and vendors commonly absorb all transportation and labor costs in per-unit or per-gallon quotations.
