To be fair, it probably doesn't affect a lot of individuals in the US, since our de minimis is $800 [1]. Compare to e.g. Canada ($20 CAD).

Let's say after 2019-01-01 I want to purchase a $500 gadget that's being hit with the 25% tariff. I can either:
1. Buy it from Amazon or a local retailer and pay $500 x 1.25 x 1.085 (state and local sales tax) = $678
2. Buy it online from AliExpress/BangGood and pay $500 + shipping
It does become a loophole if the duty is much higher than the price of shipping.
