China is the world's top graphite producer and exporter. It also refines more than 90% of the world's graphite into the material that is used in virtually all EV-battery anodes, which is the negatively charged portion of a battery.

"This bold and unexpected move by China in graphite has taken us by surprise, arriving far sooner than anyone could have predicted," says Kien Huynh, chief commercial officer at Alkemy Capital Investments, which is focused on developing projects in the energy transition metals sector.

Beijing requires the export permits at a time when many foreign governments are ratcheting up pressure on Chinese companies over their industrial practices.

The European Union is considering levying tariffs on Chinese-made EVs, arguing they unfairly benefit from subsidies. Also, the US government earlier this week widened curbs on Chinese companies' access to semiconductors, including stopping sales of more advanced artificial intelligence chips made by Nvidia.

US President Joe Biden discussed critical minerals in Washington on Friday with EU officials as part of a wide-ranging set of negotiations.

China's graphite curbs are similar to those imposed since August for two chip-making metals, gallium and germanium. The restrictions have slashed exports of those metals recently and pushed up prices outside of the country.

The action is intensifying efforts among miners outside China to bring graphite projects to fruition while efforts to find alternatives will also be ramped up.

"What China is saying to the West with this decision is that they are not going to help other countries make electric cars, as they would have to find their own way to do that," Northern Graphite CEO Hugues Jacquemin says.

China's commerce ministry said the move on graphite was "conducive to ensuring the security and stability of the global supply chain and industrial chain, and conducive to better safeguarding national security and interests".

It added that it was not targeting any specific country. Top buyers of graphite from China include Japan, the United States, India and South Korea, according to Chinese customs data.

Under the new restrictions, China will require, as of December, that exporters apply for permits to ship two types of graphite, including high-purity, high-hardness and high-intensity synthetic graphite material, and natural flake graphite and its products.

Three types of "highly sensitive" graphite items have already been under temporary controls, the commerce ministry said, and have been included in the new list.

Meanwhile, it dropped temporary controls on five less sensitive graphite items used in basic industries such as steel, metallurgy and chemicals.

With rising sales of electric vehicles, automakers are racing to lock in supplies from outside China, but shortages are looming.

"With this new graphite export curb, South Korean firms, which heavily rely on China for graphite imports, would need to seek alternatives such as mines from the United States or Australia, but it would likely increase the cost burden for many," says Kang Dong-jin, an analyst at Hyundai Motor Securities.

South Korea’s trade ministry said in a statement that it had held a meeting with battery and material makers on how to respond to the export curbs.

"The South Korean government will closely communicate... to avoid production disruptions in the lithium-ion battery sector,” according to South Korea’s industry minister, Ahn Duk-geun.

Japan's top government spokesperson, Hirokazu Matsuno, says the country plans to ask China about the "operational policies" of the new measures and will "take appropriate steps" if they violate World Trading Organization rules.

Shares in China's new energy vehicle and battery makers rose after the announcement.

Analysts said it was not clear how much impact the new measures on graphite will have in the short term.
