Refractories: Market Size & Forecast 2026

The global refractories market stands at approximately USD 32.5 billion in 2025 (base year), held in a structurally tight balance between structurally inelastic iron-and-steel lining demand, a magnesia-alumina feedstock cost cycle that has compressed supplier margins through 2025, and a regulatory regime that is materially shifting US and EU sourcing economics. The 3.8% CAGR we expect through 2032 gets the category to roughly USD 42.2 billion, but the consensus 4.5%+ CAGR looks aggressive because it extrapolates from a one-time steel demand surge rather than underlying parc growth. Iron and steel consumes roughly 65% of all refractory output, making the category a pure proxy for the heavy-industry capex cycle, and the next 24 months are defined by three structural shifts: CBAM definitive-phase embedded-carbon obligations on magnesia and dolomite imports from 1 January 2026, Section 301 L
