Earlier quoted context omitted.
It's not that complicated. They don't pay the tariffs. The person receiving the package does. Many carriers will slap you with the tariff charge, a brokerage fee, and then send you to collections if you don't pay it. The vendors don't care because they're making the sale and the tariffs are the other person's responsibility. Caveat emptor.
> They don't pay the tariffs. The person receiving the package does. How does that work? I am assuming it’s not US as I had never got any tariff charges or brokerage fees from the likes of FedEx or UPS.
Depending on country rules, it is sometimes possible for the sender to pay and then include the charges in their delivery fees.
