Well, the U.S. gets by far the most of its aluminum imports from Canada, according to data compiled by Reuters. And on steel, Canada is also first. And there are other allies on that list, like Mexico and South Korea. You might notice that in all those countries I mentioned, Canada and Mexico feature prominently.

Trump had recently threatened tariffs on them and then paused them at the last minute. Well, with this new announcement, he's putting tariffs on those two countries anyway, just not on all of their goods. And that gets to one really important thing about these tariffs. There are no exceptions to these. And that's different from Trump's tariffs last time around.

It's also different from how Biden treated tariffs. Both of them had carve outs on tariffs for some allies, but not now.

Well, in the near term, this should be good for American steel and aluminum companies because tariffs raise the price of steel and aluminum and they protect against some foreign competition. And markets seemed to think so yesterday. Shares of Alcoa, an American aluminum company, and U.S. steel were both up. But that doesn't mean this is great for the rest of the economy.

I talked to Gary Huffbauer, a senior fellow at the Peterson Institute for International Economics. He told me that industries that use those metals, like aircraft and auto manufacturing, also bridge construction, those could lose jobs.

He's saying there that not only would prices be higher for steel and aluminum, but other countries are likely to hit back and tariff American exports, which will hurt these companies.

Well, it's unclear, but he's dribbled out a bit of information. He has said he'll be announcing what he calls reciprocal tariffs. The idea there seems to be that whatever tariff a foreign country has put on a U.S. good, he wants to impose it back in return. He also said yesterday that he'll be considering tariffs on cars, pharmaceuticals, semiconductors.

But it was unclear whether those are separate from the reciprocal tariffs. And this is one constant feature of how Trump does tariff policy. There's often not an orderly rollout. We really just don't know what's coming until he says it. I'm PR's Danielle Kurtzleben.
