(The Center Square) – Businesses worldwide are urging caution as the U.S. Trade Representative's Office prepares for key hearings central to President Donald Trump's renewed push for higher import taxes, an effort aimed at rebuilding a protectionist tariff wall.

Trump could implement the higher tariffs as early as July under Section 301 of the 1974 Trade Act, which allows the president to impose tariffs after investigating specific trade issues. The administration launched these investigations in March, with hearings set for May 5. A major concern for businesses is the possibility of exemptions. Section 301 has no established process for exclusions, but a recent Congressional Research Service report noted uncertainty about whether the Trade Representative's Office "would establish a new exclusion process for current or future tariff actions."
