NEW YORK — Trump’s tariffs are headed to court — again. Two lawsuits filed by small businesses are challenging Trump’s sweeping tariffs announced Thursday that impose double-digit levies on 60 trading partners. They came just as temporary 10% worldwide tariffs — that had also been challenged in court — expired. Trump used Section 301 to impose big tariffs on China in his first term, and they survived court challenges. “This suggests that no short-term path for country-wide relief from the new Section 301 tariffs will be available.’’
