Mineral Commodities with Net Import Reliance on China

USGS collects the Nation’s data on the global production, supply, demand and trade of minerals to inform strategic policy, trade and land-use decisions.

Gallium is used in gallium arsenide and gallium nitride compound semiconductors. There is additional production capacity for gallium outside China with the potential to produce gallium in Germany, Kazakhstan and South Korea in response to China’s gallium export ban to the U.S. 

The United States continues to rely on foreign sources for some raw and processed minerals materials, including some critical minerals. This map shows the countries that supply nonfuel mineral commodities for which the United States was greater than 50% net import reliant from 2020-2023.

USGS leads the government in developing the List of Critical Minerals. UGS is required to update the List at least once every three years. The process for developing the List of Critical Minerals is laid out in the Energy Act of 2020 (Section 7002).

Formulation and expert input

Mineral Supply Risk Analysis for the 2022 List of Critical Minerals

The USGS leads the government in developing the List of Critical Minerals, using a data-driven methodology to assess mineral supply risk.

Critical minerals are essential the Nation’s economy and security, and have supply chains vulnerable to disruption. 

Earth MRI: The First Five Years

The Earth Mapping Resources Initiative (Earth MRI) is modernizing the Nation’s mapping and geoscience data, benefitting regions, states and local communities.

By the Numbers:

40 States and Territories partnered with Earth MRI
