Overview
- Four BYD subsidiaries filed the case on Jan. 26 at the U.S. Court of International Trade, docketed as No. 26-00847.
- The complaint argues IEEPA does not authorize tariffs, seeking declaratory relief, injunctions against enforcement, and refunds of duties paid since April 2025 with interest.
- The suit challenges nine executive orders issued since February 2025, including tariffs at the borders with Mexico and Canada and measures tied to China and fentanyl.
- BYD’s filing is the first tariff lawsuit by a Chinese automaker, and the company says it acted to preserve refund rights while tariffs remain in place.
- BYD operates U.S. businesses in buses, batteries, energy storage and solar, employing about 750 workers in Lancaster, California, as a separate Supreme Court review of the tariffs proceeds with officials noting the stakes are enormous.
