President Donald Trump is set to unveil the details of his tariff plans at 4 pm ET on Wednesday, April 2. He has vowed to impose reciprocal tariffs on all nations that he claims disadvantage American products through trade, tax, or regulatory policy.Trump has already imposed tariffs on steel and aluminum made outside the US, all products made in Canada or Mexico, all Chinese goods, and all foreign-made cars, among other things, claiming these moves will strengthen the economy long-term while downplaying concern theyll lead to a recession.
