WASHINGTON - A U.S. trade court on Thursday ruled against the 10 percent global tariff imposed by President Donald Trump's administration earlier this year, dealing another blow to a pillar of his economic agenda.

The tariff took effect in February to replace Trump's so-called reciprocal duties targeting almost all U.S. trading partners, as well as fentanyl-related levies he applied to goods from China, Canada and Mexico, after the Supreme Court invalidated them.
