Problematic Rare Earths

Since early April, Chinese customs officials have blocked shipments of rare earth magnets at numerous ports. This halt comes as Beijing drafts a new regulatory framework for export licensing, a move interpreted as retaliation for the US government’s latest round of tariffs.

The materials in question are indispensable for the manufacture of high-performance electric motors used in electric vehicles (EVs), and robotics; vital to vehicle production. Even conventional combustion-engine vehicles rely on electric motors with rare earth magnets for vital functions such as steering.

Industry observers say it’s critical for the Detroit automakers a deal is reached.

And as usual, the United States is late to the game and playing catchup.
