So I am far from an expert, but I saw that Capital Economics (a Macroeconomic analysis firm) put out a note saying that Trump still had power under Section 122 of the Trade Act of 1974. But there are three catches for that. First, it only lasts for 150 days unless Congress votes to approve them. Second, that it has to apply to all countries equally: meaning that it can't be used to give some countries a break if they sign a deal, so all of the deals are going to be unenforcable on America's end. Third, it caps the tariff rate at 15%.

Like with refunds, this is a mess of Trump's own making, and now we get to figure it out.

They've already voted once that a day isn't a day to avoid having to maintain some of his emergency declarations so I don't think that 150 day timer will actually end up running.
