Just circling back - it's almost certain that the administration conflated trade deficits and tariffs. I found a good breakdown, reposting the receipts here:
These "tariff" numbers provided by the administration are just ludicrous. They don't reflect any version of reality where real tariffs are concerned. I was convinced they weren't just completely made up, though, and their talk about trade balances made me curious enough to dig in and try to find where they got these numbers.
This guess paid off immediately. As far as I can tell with just a tiny bit of digging, almost all of these numbers are literally just the inverse of our trade balance as a ratio. Every value I have tried this calculation on, it has held true.
I'll just use the 3 highest as examples:
***Cambodia: 97%***
US exports to Cambodia: $321.6 M
Cambodia exports to US: 12.7 B
Ratio: 321.6M / 12.7 B = ~3%

***Vietnam: 90%***
US exports to Vietnam: $13.1 B
Vietnam exports to US: $136.6 B
Ratio: 13.1B / 136.6B = ~10%

***Sri Lanka: 88%***
US exports to Sri Lanka: $368.2 M
Sri Lanka exports to US: $3.0 B
Ratio: ~12%

What the Administration appears to be calling a "97% tariff" by Cambodia is in reality the fact that we export 97% less stuff to Cambodia than they export to us.
