So, when I paid my tariff, I received some additional detail and the amount was a little lower. The tariff was $44 plus fees of $97 for a total of $141. So, the tariff was roughly 12% of the invoice. However, fees were more than double the amount of the tariff. And I have no idea what the fees were for, were they merchandise processing fees or customs clearing fees or brokerage fees or some other fee? They don't tell you.
I actually had a little sympathy for UPS in the beginning of this whole process. I could imagine if I were running a shipping business and suddenly had to worry about being secondarily liable on tariffs, and needed to set up systems to collect a tax immediately, with no small dollar exemption, no time to plan, and constantly changing requirements, that would be a real pain in the ass. I can even understand the decision to make it as painful as possible for the consumer, in the hopes this would diminish the popularity of the tariffs. Again, as a business person, I can see the strategy here.
That said, I'll henceforth be looking for alternatives to UPS.
