Overview
- Four U.S. subsidiaries of BYD filed the case in the U.S. Court of International Trade in January, with the filing disclosed in court records reported on February 9.
- The action marks the first lawsuit by a Chinese carmaker challenging the reciprocal tariffs imposed under the Trump administration.
- BYD seeks repayment of duties it says it has paid since April 2025 under the contested measures.
- The complaint contends the International Emergency Economic Powers Act lacks any reference to tariffs, so it cannot be used to levy them.
- The suit joins a broader wave of challenges by thousands of multinational firms, and a report says the measures’ legality is under review at the U.S. Supreme Court.
