Geopolitical Impact Analysis

Strategic Mineral Policies and Regional Sourcing Accelerating Dolomite Industry Resilience

Geopolitical uncertainty and trade disruptions have prompted governments to strengthen domestic mineral supply chains, indirectly supporting demand for industrial minerals such as dolomite used in steel, glass, refractories, and infrastructure. According to the European Commission’s Critical Raw Materials Act (2024), the European Union has set targets to source at least 10% of its annual strategic raw material consumption through domestic extraction, process 40% within the EU, and recycle 25% by 2030. Although dolomite is not classified as a strategic raw material, these policies are encouraging investment in regional mineral processing and reducing dependence on external suppliers, creating a favorable environment for industrial mineral producers.

Geopolitical diversification is also reshaping downstream industries that consume dolomite. According to the U.S. Department of Energy, the United States allocated US$6 billion in March 2024 under the Industrial Demonstrations Program to accelerate decarbonization across energy-intensive industries, including iron and steel, cement, and glass manufacturing. As these sectors expand domestic production capacity and modernize facilities, demand for refractory and flux materials such as dolomite is expected to strengthen alongside regional supply chain development.
