It wasn't the tariff. UPS has been tacking on a ridiculously high paperwork fee for the service of processing tariff payments. Other shipping companies have also had fees, but UPS is the main one that's made it exorbitant and disproportionately higher than the tariff itself.
I'm thinking the delivery agents such as UPS, Fedex, USPS now need to sue the United States so they can pay back all the recipients the fees they charged, plus interest.
There are going to be a raft of class action suits based on this.
As one of my lawyers once said, the only winners here are the lawyers.
