Understanding the US Department of the Interior Critical Minerals List
The US Department of the Interior (DOI) Critical Minerals List identifies mineral commodities vital for America's economic prosperity and national defense capabilities. Updated triennially as mandated by the Energy Act of 2020, this list serves as a strategic roadmap guiding federal policies, investment priorities, and permitting decisions with the ultimate goal of reducing foreign dependency and strengthening domestic supply chains.
The list originated from a 2017 Executive Order that initiated comprehensive analysis of supply chain vulnerabilities for critical minerals. The 2025 draft list represents the second formal iteration since this process was established and includes 54 mineral commodities deemed essential for American economic and national security interests.
According to Secretary of the Interior Doug Burgum, "This draft List of Critical Minerals provides a clear, science-based road map to reduce our dependence on foreign adversaries, expand domestic production and unleash American innovation." This statement underscores the strategic importance the administration places on securing reliable mineral supply chains.
How Does the DOI Determine Which Minerals Are Critical?
The New Economic Impact Assessment Framework
The 2025 draft list introduces a revolutionary approach to evaluating mineral criticality. Moving beyond traditional supply disruption risk analysis, the US Geological Survey (USGS) now employs a comprehensive economic impact assessment framework that offers unprecedented insight into vulnerabilities across the entire US economy.
This sophisticated methodology evaluates over 1,200 potential trade disruption scenarios, analyzing how 84 different mineral commodities might affect 402 individual US industries if supply chains were compromised. The framework weighs economic consequences against the probability of each disruption scenario occurring, providing policymakers with clear economic metrics that can be directly compared with other national priorities.
This approach represents a significant advancement over previous assessment methods, which often relied more heavily on qualitative factors rather than quantitative economic impact calculations.
Supply Chain Vulnerability Analysis
The assessment examines multiple vulnerability factors to create a holistic picture of risk:
- Concentration of global production in single countries
- Technical limitations in finding substitute materials
- Current recycling rates and recovery challenges
- US import reliance percentages for each mineral
- Processing capacity bottlenecks across supply chains
- Geopolitical stability concerns with supplier nations
By combining these factors with probability-weighted economic impact calculations, the USGS provides a nuanced understanding of which minerals truly represent the greatest vulnerabilities to American economic security.
