A tariff is a charge paid by the domestic purchaser to the government. Like when you order something from across a border and get a surprise duty. Goods are purchased from abroad because they are not available domestically, or are cheaper produced abroad. To instantly tax companies and families on essentials that are not available domestically or are drastically more expensive when they are, of course there is going to be hardship but that's what a tariff is.

If this is obvious to someone remembering it from economics 101 (and didn't get an A,) I am not sure why people believed the foolishness that other countries would pay the tariffs?
