Here's something interesting from your link:

This implies that the average US import tariff has increased by about three percentage points, to 5% or so, which does not appear excessive.
I think 5% is a little high, because the average U.S. rate before the tariffs on Chinese products was probably a tad lower than 2%. And we're not importing as much from China as we once were. Still, the USA now has by far the highest average tariff rate of any country in the developed world, if you define "developed world" as Europe, Japan, Australia, New Zealand and Canada. China's average tariff rate was only 3.83%, although it should be higher now that they've placed additional tariffs on U.S. imports. See
