What to know about Trump’s new tariffs on more than 80 countries

Tariffs ranging from 10%-12.5%, taking effect on Friday, are US president's latest effort to circumvent Congress

Just before a temporary levy on global imports was set to expire, the Trump administration issued a fresh wave of tariffs on more than 80 countries late on Thursday, ranging from 10% to 12.5%. The new tariffs take effect Friday morning.

It's Donald Trump's latest effort to continue imposing global levies without congressional approval, despite the supreme court ruling in February that found the US president had illegally used his executive power to implement his global trade policies. Trump has long maintained that the US has been paying more than its fair share in tariffs, and that increased duties are necessary to boost American manufacturing and jobs.
