Last updated: August 2026 dataCalcium chloride is a hygroscopic salt with major commercial applications in road deicing, dust suppression on unpaved roads, oil and gas well completion fluids, concrete acceleration, and food processing as a firming agent. Its high exothermic heat of dissolution makes it more effective than sodium chloride for low-temperature deicing, driving seasonal import demand spikes ahead of winter in northern markets. Food-contact and food-additive grades must meet FDA purity requirements, and importers of those grades should ensure the foreign manufacturer's facility is registered with FDA.

Demand for deicing-grade calcium chloride peaks in late summer and autumn as distributors build inventory ahead of winter road maintenance contracts in northern US states and Canada. Importers and logistics providers need to plan vessel bookings and warehouse capacity well in advance of the season, as spot availability tightens significantly from September onward.
Yes. Calcium chloride is commercially available in flake, pellet, liquid (solution), and powder forms, with purity levels ranging from roughly 77% to over 94% on an anhydrous basis. Deicing and dust-control grades tolerate lower purity, while food-additive (FCC) and pharmaceutical (USP) grades require higher purity and lower heavy-metal limits. The physical form and concentration affect freight costs and storage requirements, and should be specified precisely in purchase contracts.
