Amazon Haul.. what does that imply?

7

While checking my Amazon account today an announcment came up having to do with Amazon Haul. This seems to be designed to compete with Temu et al. As you can see from the screenshot this lists YOU as the importer (I haven’t used Temu so I’m not sure how they classify you).
enter image description here
Under the “learn more” link it says you are responsible for the fees, customs etc. Does this mean you’ll get stuck with a bill for any tariffs (which are generally paid by the importer)? Will you come back and get re-billed (at a different price) in order to cover that fee? How would you know what it’s going to be before you place your order? Will it be paid through your Amazon account or directly to a billing from the US government?
So many questions!
