Rock Salt: Market Size & Forecast 2026

The global rock salt market sits at approximately USD 4.8 billion in 2025 (base year), held in a structurally stable balance between mature North American and European de-icing demand, steady industrial channel consumption, and a modest capacity-add pipeline that has not yet disturbed the supply-demand equilibrium. Road de-icing applications dominate at 58 percent of end-use volume, anchoring the category to seasonal weather patterns and public-sector budget cycles. The US Producer Price Index for Rock Salt (WPU06130271) traded in the 424-440 band across April-July 2025, indicating price firmness rather than stress. We project a 3.2 percent CAGR through 2032, reaching roughly USD 6.0 billion, with the USD 48/MT US Gulf crude benchmark serving as our directional pricing anchor. > **Analyst Take.** The 3.2 percent headline CAGR is roughly right, but the composition is wrong: most third-par
