US critical minerals list expands to 60 materials

US critical minerals

The US critical minerals list has expanded to 60 materials, reshaping policy for metals, energy and agriculture. The updated US critical minerals list now adds boron, copper, lead, metallurgical coal, phosphate, potash, rhenium, silicon, silver and uranium. As a result, the US critical minerals list will guide US industrial strategy, investment priorities and supply chain risk management for years.

Why the US critical minerals list matters for industry

The new list reflects rising concern over supply chain vulnerability and geopolitical risk. US law requires the US Geological Survey to review critical minerals every three years, based on domestic manufacturing needs and import exposure. This process now captures more metals with defence, clean energy and advanced manufacturing applications.

Government agencies played a decisive role in shaping the final list. The Department of Defense pushed to keep arsenic and tellurium, citing key national security uses. The Department of Energy backed metallurgical coal and uranium because of their importance for steel, power generation and defence. These decisions show how critical mineral policy is converging with broader security and industrial goals.

Boron’s inclusion highlights growing dependence on specialised inputs for steelmaking and high-tech uses. The US relies heavily on ferro-boron imports from China, creating a strategic vulnerability. By classifying boron as critical, policymakers can prioritise domestic projects, alternative suppliers and recycling pathways.

Agriculture, fertilizers and the critical minerals agenda

Fertilizer inputs now sit squarely inside the critical minerals framework. Phosphate and potash both entered the list, reflecting their central role in food security. Industry group The Fertilizer Institute welcomed the move, expecting clearer policy support for investment and capacity growth.

Phosphate’s addition is especially significant for US farmers. Market participants and officials had campaigned for its inclusion after the draft list omitted it. The US Department of Agriculture ultimately backed phosphate as a critical mineral because crop yields and global food stability depend on reliable, affordable supply.

As a result, fertilizer supply chains may see more targeted incentives, permitting support and risk monitoring. Recognising phosphate and potash as critical could reduce price volatility and import shocks, while encouraging long-term domestic production and storage strategies.

 

The Metalnomist Commentary

Washington’s broader US critical minerals list strategy now clearly reaches beyond battery metals into steel, energy and fertilizers. By aligning national security, climate policy and food security inside one critical minerals framework, the US is quietly redrawing the map of “strategic materials.” For miners, processors and recyclers, this list will increasingly shape where capital flows and which projects move fastest through the policy pipeline.
