In 2018 Congress ordered the Pentagon to purchase only non-Chinese-made NdFeB magnets and magnet alloys but didn’t rule out raw materials from that nation. China’s share of the world’s RE mining has declined in recent years, but it still makes about 90% of NdFeB metal and magnets; Japan produces nearly all of the rest.
