BMW has joined Chinese producers in filing a challenge at the Court of Justice of the European Union (CJEU) against EU tariffs on China-made electric vehicles (EVs), according to a filing on the court's website.

The EU imposed tariffs on China-made EVs at the end of October after an anti-subsidy investigation. The rate for BMW, which manufactures the electric Mini Cooper and electric Mini Aceman in China, is 20.7%.

The court document showed the German automaker lodged its complaints at the General Court, the lower of two CJEU chambers, on Tuesday, a day before 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.

Chinese electric vehicle makers BYD, Geely and SAIC and auto sector body CCCME have also challenged the EU's import tariffs at the court.
