In terms of policy this is a truly massive gift to importing companies. They had to pay massive amounts of tax to import goods. Analysis shows most (but not all) of the tariffs were passed on down the line to consumers of the imported goods or their derivatives.
And now they get it all back! If they can figure out the paperwork. Which I expect most will, because if you import things and pay tariffs, you have to be good at govt paperwork.
Wow. I don’t know what this means. But it’s a huge windfall to a very specific horizontal slice of the economy - cutting across industries and supply chains. Just whoever happened to be doing the importing gets a giant present. So bizarre. Economists will write about this case study for decades.
