BYD Sues US Government Over Trump-Era Tariffs, Challenges Legal Authority

• Chinese EV giant BYD's four US subsidiaries have sued the US government over tariffs imposed under the International Emergency Economic Powers Act (IEEPA).
• The lawsuit, filed in the US Court of International Trade, targets executive orders affecting BYD's passenger vehicle sales, commercial vehicle manufacturing, and battery supply.
• BYD seeks a ruling that the US government lacks statutory authority for these tariffs, invalidation of orders, permanent injunctions, and financial relief including tariff refunds.
• This marks the first time a Chinese automaker has directly challenged US tariffs through the courts, setting a potential precedent for other Chinese companies.
• Industry observers note the tariffs are protectionist, affecting both domestic and foreign automakers and posing risks to global supply chains.
