<h1>US delays new tariffs under 1977 law amid legal challenges and trade impact concerns</h1> The US administration delayed the implementation of new tariffs on imports from 66 countries, including the EU and Taiwan, by one week to update the tariff schedule. The tariffs, imposed under a 1977 law declaring a national emergency, face legal challenges questioning the president's authority to bypass Congress. The tariffs vary significantly among countries, with some rates increasing and others decreasing, amid ongoing trade negotiations. The measures aim to reduce the US trade deficit and boost domestic manufacturing but risk raising inflation and harming economic growth. Several countries remain uncertain about their tariff rates, and major companies warn of financial impacts. Federal judges have expressed skepticism about the legality of the tariffs, and the case may reach the Supreme Court. The tariffs have not yet resulted in increased manufacturing jobs, and inflation concerns have influenced Federal Reserve policy decisions.
