My theory would be that a lot of companies imported a ton in the first quarter knowing that tariffs were coming.
I also personally did that for expensive gear I was otherwise planning on waiting on. And now I'm not going to be buying that over the next 2-5 years like I was originally planning.
It's a big bolus of spending that will not be replicated in the future.
Last week I was looking at a proposal from a supplier that's got a ~8K "tariff" line on it and thinking... y'know, I can wait on that project.
