Earlier this summer, the Chinese government implied that it might halt exports of rare earth elements to the United States as its next step in the ongoing trade war. These minerals serve as crucial elements in the manufacturing of a wide range of technology products, and American leaders worry that if China follows through on its threat, it will cripple the US economy and threaten national security. But these fears are misguided — there are other available sources for rare earth materials and components made from them, like Australia and Japan, that can be tapped into if China follows through on its threats.

Rare earth elements are like technology “fairy dust.” Very small amounts of these materials — including neodymium, dysprosium and yttrium — contribute to many signature products of the modern world, such as cell phones, electric cars, wind turbines and precision weapons.

In the face of this supposed threat to national security resulting from China’s potential cutoff of rare earth supply, politicians are racing to do something. Unfortunately, in their panic they are showing willingness to compromise the American business ethos.

Some in the Trump administration generally lean toward protectionism, and in late 2017, the president signed an executive order seeking to “increase activity at all levels of the supply chain, including exploration, mining, concentration, separation, alloying, recycling and reprocessing critical minerals.” And recently, using the Defense Production Act, originally enacted in 1950, the Pentagon has begun making inquiries to assess domestic processing and manufacturing capacity for rare earths, likely to begin the process of offering subsidies for rare earth production.

Additionally, US legislators, including some generally considered friendly to free trade, have introduced bills to give special treatment to the US rare earth industry. Senator Marco Rubio of Florida introduced a bill to exempt the rare-earth processing industry from antitrust law; others, like Alaska’s Senator Lisa Murkowski, have sought to relax permitting requirements for companies seeking to open new mines.

But the government doesn’t need to step in. There are plenty of sources for rare earth materials that US tech manufacturers can tap into.

The Mountain Pass mine, located in Mountain Pass, California, had been producing rare earth minerals since the 1950s when it closed in 2002. But now, under new ownership, the mine is operating profitably at commercial scale as MP Materials.
