BYD, the world's largest electric vehicle manufacturer, has filed a lawsuit against the U.S. government challenging tariffs imposed under the International Emergency Economic Powers Act, marking the first legal action by a Chinese automaker over U.S. trade policy.
Four of BYD's U.S. subsidiaries filed the case on Jan. 26 in the U.S. Court of International Trade, case number 26-00847, according to court documents reported by Reuters. The plaintiffs argue that IEEPA does not authorize the president to impose tariffs, stating that the law "does not employ the word 'tariff' or any term of equivalent meaning."
The lawsuit seeks to void nine tariff executive orders, halt their enforcement, and recover all duties BYD has paid since April 2025, plus interest.
Why it matters for collision repair
The case joins thousands of lawsuits challenging IEEPA tariff authority, and the outcome could affect far more than one Chinese automaker. Collision repair shops have absorbed tariff-driven cost increases throughout 2025, with parts prices rising more than 6% in the second and third quarters, according to CCC Intelligent Solutions.
If courts ultimately strike down IEEPA tariffs, the relief could extend to a broad range of imported auto components. About 44% of all OEM collision parts sold in the U.S. are manufactured overseas, according to PartsTrader. But any such relief remains distant: the legal timeline stretches well into 2026 or beyond, and even a favorable ruling would face implementation challenges.
The legal landscape
BYD's case is now stayed, along with thousands of similar lawsuits, pending a U.S. Supreme Court decision in V.O.S. Selections v. Trump and Learning Resources v. Trump. Both the Court of International Trade and Federal Circuit Court of Appeals ruled that IEEPA does not authorize the president to impose tariffs, findings the government appealed.
The Supreme Court heard oral arguments on Nov. 5, 2025. U.S. Trade Representative Jamieson Greer said the court is taking its time given the "enormous" stakes involved, according to Reuters. Legal analysts expect a ruling in early 2026, though timing is not guaranteed.
BYD stated it filed an independent complaint to preserve its ability to receive refunds for tariffs already paid, a common strategy among importers navigating the legal uncertainty.
BYD's U.S. presence
While BYD does not sell passenger vehicles in the United States, the company has significant operations here. Its Lancaster, Calif., truck plant employs approximately 750 workers and produces electric buses for municipal transit agencies. BYD's U.S. business also includes commercial vehicles, batteries, energy storage systems, and solar panels.
The company has become the world's leading EV seller after overtaking Tesla in global battery-electric sales. The National Automobile Dealers Association has warned that Chinese OEMs could undermine fair competition due to state-backed industrial advantages, according to Autoblog.
What shops should do
The BYD lawsuit doesn't change the current tariff landscape for collision repair shops, but it signals continued legal volatility in trade policy.
For shops tracking the tariff outlook, the Supreme Court ruling in the V.O.S. Selections case will be the key development to watch. If the court invalidates IEEPA tariffs, importers who filed protective claims could receive refunds, and the broader tariff structure affecting automotive components could shift.
In the meantime, the pattern shops have navigated throughout the last year continues: monitor quarterly tariff inclusion windows under Section 232, track OEM guidance on pricing changes, and maintain documentation for insurer discussions when tariff-related cost increases affect repair estimates.
