BRUSSELS, Jan 27 (Reuters) - Tesla has joined

BMW and Chinese producers in filing a challenge at the Court of

Justice of the European Union (CJEU) against EU tariffs on

China-made electric vehicles, according to a filing on the

court's website on Monday.

The challenge will open a new front in Brussels' conflict

with Elon Musk, Tesla CEO and ally of U.S. President Donald

Trump. Earlier this month, the EU stepped up its probe into

Musk's social media platform X over content moderation.

The EU imposed tariffs on China-made EVs at the end of

October after an anti-subsidy investigation. The rate for Tesla

was 7.8%, lower than any of its competitors.

The court document showed the U.S. automaker lodged its

complaint at the General Court, the lower of two CJEU chambers,

last Wednesday, the deadline for filing challenges. Proceedings

at the General Court last on average 18 months and can be

appealed.

No further details of the cases were given.

BMW, Chinese electric vehicle makers BYD, Geely

and SAIC, and auto sector body CCCME have

also challenged the EU's import tariffs at the court.
