The United States primarily imports gadolinium, a rare earth element, from China, which is the major miner and refiner, but also produces a small amount from its one American rare earth element mine at Mountain Pass in California. 

 

Here's a more detailed breakdown:

• Main Source:

  China is the dominant global supplier of gadolinium. 

   
• US Production:

  The US has a small-scale rare earth element mine at Mountain Pass, California, which contributes to a limited amount of domestic gadolinium production. 

   
• Other Refiners:

  While China is the primary source, other countries like those in the European Union, Korea, and Japan also refine gadolinium for export.
