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 rock salt, solar salt, and ice melt products for winter road maintenance, snow and ice control, and facility operations. The code sees active procurement across state departments, cities, counties, and school districts, with issuing bodies ranging from state transportation departments to municipal public works departments and school districts. Recent solicitations show state highway departments and city public works divisions are the primary buyers, with activity concentrated in jurisdictions facing winter weather demands and facilities maintenance needs across multiple seasons.
