Yet that law only allows tariffs of up to 15% for 150 days.

The broader point of the court’s ruling is that since Congress has the power to impose tariffs under the Constitution, it can only delegate that power to the president under specific laws the president has to follow.There are several Trump could use, including Section 301 of the 1974 Trade Act, but that does require an investigation of another country’s trade practices to establish that they either violated a trade agreement or engaged in unfair trade practices.

Another possibility is Section 338 of the Trade Act of 1930, which allows tariffs of up to 50% for countries that have discriminated against U.S. imports. It doesn’t require a government agency to investigate anything. And Section 201 of the 1974 Trade Act allows duties to be imposed of up to 50%, but only after an investigation that establishes that imports have harmed a specific U.S. industry. That law was used to slap tariffs on some solar products in 2018.If the courts uphold Wednesday’s ruling and the import taxes are struck down, the money will be refunded back to the U.S. companies that paid it.
