Mojave,
You’re missing a pretty fundamental point; you can increase the number of items with tariffs (the number of Harmonized Tariff Schedule codes), but decrease the rate of all existing tariffs such that the total tariffs paid are lower.
Essentially, if I double the number of tariffs but cut all the tariff rates by a factor of four, I cut the total tariff revenue in half.
So I’ve satisfied those who demand “we need tariffs!” by adding tariffs, and I satisfy those who demand “we should eliminate tariffs!” by reducing the total tariff taxation.
Did that happen?
