Critical Minerals Supply Chain

A critical minerals supply chain refers to the linked stages — extraction, concentration, smelting, refining, component manufacturing, and recycling — that move minerals classified as "critical" from the ground into finished technologies. Governments designate minerals as critical based on their importance to clean energy, defense, and high-tech industries, combined with the risk of supply disruption. Common entries on these lists include lithium, cobalt, nickel, graphite, manganese, and the seventeen rare earth elements, along with copper and silicon in some jurisdictions.

Each major economy maintains its own designation. The U.S. Geological Survey publishes a list of critical minerals under the Energy Act of 2020, updated periodically. The European Union's Critical Raw Materials Act, which entered into force in 2024, sets benchmarks that no more than 65% of any strategic raw material consumed in the EU should come from a single third country, alongside domestic extraction, processing, and recycling targets for 2030. Japan, Australia, Canada, and the UK maintain comparable frameworks.

Supply chain concentration is the central policy concern. According to the International Energy Agency's Critical Minerals Outlook reports, China processes a dominant share of global rare earths, graphite, and refined cobalt, while the Democratic Republic of the Congo accounts for the majority of mined cobalt and Indonesia leads in nickel.

Policy responses include:

• Friend-shoring arrangements such as the U.S.-led Minerals Security Partnership launched in 2022.
• Domestic subsidies under the U.S. Inflation Reduction Act (2022), which conditions EV tax credits on sourcing from the U.S. or free-trade partners.
• Export controls, including China's 2023–2024 restrictions on gallium, germanium, and certain graphite products.
• Stockpiling, recycling mandates, and World Trade Organization disputes over export quotas.

For MUN delegates and researchers, the file sits at the intersection of trade, climate, development, and security policy, and surfaces in committees ranging from UNEP and UNCTAD to the WTO and the IAEA.
