Trade court hears arguments on legality of Trump’s new global tariffs

Key points

• A three-judge panel at the US Court of International Trade heard arguments on Wednesday regarding the legality of new tariffs imposed on goods from 80 to 86 countries.
• The new tariffs, ranging from 10% to 12.5%, were imposed after the Supreme Court struck down previous global tariffs and a separate 10% duty expired.
• Plaintiffs, including the Liberty Justice Center and small businesses, argue the administration is improperly using Section 301 to achieve a predetermined global tariff policy.
• The administration claims the tariffs are justified by foreign countries' failure to address forced labor in their supply chains.
• A ruling is expected soon, but the case could be appealed to the Federal Circuit and potentially the Supreme Court, extending the legal battle for months.

Background

This legal challenge follows a series of recent tariff disputes. In February 2026, the Supreme Court struck down Trump's 'reciprocal' tariffs, leading to a $168 billion refund for importers. Subsequently, the administration imposed a 10% tariff under Section 122, which was later invalidated by a federal trade court. The current Section 301 tariffs were introduced in July 2026 as the Section 122 duties expired. Additionally, the administration has been pursuing separate tariff measures against Canada using Section 338 of the Tariff Act of 1930, which faces its own legal scrutiny.

How outlets are covering it

CNN and CNBC both report on the court arguments, but emphasize different aspects. CNN highlights the broader legal strategy, noting that the administration is using various trade laws to achieve its trade policy objectives, and mentions the potential for further legal battles. CNBC focuses more on the specific arguments made by the plaintiffs and the administration during the hearing, detailing the 'pretext' argument and the administration's defense of its country-by-country analysis. Both outlets agree that the new tariffs are a significant legal challenge for the administration's trade agenda.

Why it matters

The outcome of this case could determine the legality of a major component of the Trump administration's trade policy. If the tariffs are struck down, it could lead to significant refunds and disrupt global trade. If upheld, it could set a precedent for the use of Section 301 for broad tariff measures. The case also highlights the ongoing legal battles surrounding the administration's trade policies and their potential impact on global trade and the US economy.

What to watch

The court is expected to issue a ruling soon, but the case could be appealed to the US Court of Appeals for the Federal Circuit and potentially the Supreme Court. The administration has also indicated that it may impose additional tariffs under Section 301 and other trade laws. The legal battle is likely to continue for several months, with potential implications for global trade and the US economy.
