>it wasn't even remotely the same
I think everyone can agree that in both 2018 and 2025: 1) Donald Trump announced sweeping tariffs on major trade partners - among which China, Mexico and Canada; 2) most media predicted a large-scale disaster; 3) large parts of the tariffs were later cancelled entirely, delayed, or scaled back.
I'm not sure what part of that "isn't even remotely the same." You highlight the low average tariff rates by country despite the (large) first Trump tariffs. This is _exactly_ my point: when you account for all exemptions, changes, agreements, rerouting of trade etc, the marquee double-digit numbers shrink dramatically.

As for the exact number, obviously it is impossible to know, and there are many ways to measure it. It's not uncommon for two estimates of tariff revenue, both calculated in honest ways, to be widely at odds. This is one reason why I qualified my numbers as "very rough", but I did lay out my reasoning above. To make it simple: most groups (CRFB, Tax Foundation, etc) estimated the tariffs we were discussing (China +10, Canada/Mexico +25) to sit - very roughly - at 100B of revenue raised plus or minus a few tens of billions. Current US tariff revenue is approximately 100B. So, in other words, we're talking about an approximate doubling of mean tariffs, which stand at around 1.5-2% today depending on who you ask and how it is measured.
