NextFin news, On Thursday, September 25, 2025, the US Court of Appeals for the Federal Circuit upheld the legality of the tariffs imposed on Chinese imports by the Trump administration during its first term. The court ruled that the tariffs, challenged by importers as unlawful, were authorized under existing trade laws.
Judge Todd Hughes, writing for a three-judge panel, stated that Section 307(a)(1)(C) of the Trade Act authorizes the United States Trade Representative (USTR) to take escalatory and modified trade actions. The court found that the USTR’s remand redetermination complied with the procedural requirements of the Administrative Procedure Act (APA), thereby affirming the trial court’s decision to sustain the challenged tariff lists, known as Lists 3 and 4A.
The tariffs in question were part of a broader set of trade measures implemented by the Trump administration aimed at addressing trade imbalances and unfair trade practices by China. These tariffs targeted a wide range of Chinese goods and were a central element of the administration’s trade policy.
The ruling came after importers and other stakeholders contested the tariffs, arguing that they were imposed without proper legal authority. The appeals court’s decision rejects these claims, confirming the administration’s authority to impose such tariffs under the cited statutory provisions.
This decision is significant as it reinforces the legal framework supporting the use of tariffs as a tool in US trade policy, particularly in disputes involving China. It also provides clarity for businesses and policymakers regarding the scope of the USTR’s authority.
The case was heard by the US Court of Appeals for the Federal Circuit, a specialized court with jurisdiction over trade and patent matters. The ruling was issued on September 25, 2025, and is expected to influence ongoing and future trade litigation involving tariffs and trade remedies.
