Mercedes-Benz Group AG is joining a Geely lawsuit against European Union tariffs on electric cars imported from China, adding to a flurry of legal cases targeting the duties.

Mercedes-Benz has joined its Chinese joint venture partner Geely's legal challenge at the Court of Justice of the European Union (CJEU) against EU tariffs on China-made electric vehicles, a company spokesperson said on Tuesday.

Chinese EV makers BYD, Geely, and SAIC contested EU's import duties at Court of Justice. Tesla excluded from tariffs, gaining only 7.8% tax.
