The U.S. Court of International Trade has ruled that former President Donald Trump's global 10% tariff on imports is illegal, following the Supreme Court's earlier decision to strike down his emergency tariffs. This leaves Trump with diminished leverage just days before a scheduled meeting with China's President Xi Jinping, who appears to have the upper hand in negotiations. The court's ruling jeopardizes Trump's trade policy, which has relied on tariffs to encourage domestic manufacturing. While the ruling does not impose a universal injunction against tariffs, it limits refunds to only those importers who challenged the tariffs in court. This could lead to additional lawsuits from other importers and customers affected by the tariffs. Trump has indicated he will appeal the ruling and criticized the judges involved. Meanwhile, the administration faces pressure to expedite investigations into other potential tariff options, a process that could take weeks or months.
