For a mineral commodity (rare earths, gallium, germanium, cobalt, lithium, graphite, antimony, tungsten, nickel, platinum-group metals, and 70+ more), returns: world mine-production concentration by country (ranked top producers with share, China's share, and an HHI concentration score), US net import reliance and the major foreign sources, reserves concentration by country, and whether it is a USGS-designated critical mineral. Use it to assess supply-chain and geopolitical exposure — China/adversary control of a mineral, US import dependence, and single-country concentration — before a sourcing, policy, or investment decision.
