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. 

An infographic that highlights the ways that the Earth Mapping Resources Initiative (Earth MRI) gathers multiple types of data, including: topography, geology, geochemistry, geophysics, borehole information, hyperspectral imagery, mine waste and more.

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.
