Ok.

I think that the idea that the VAT (and maybe tariffs) are collected at the seller is good. It does it make it easy for the customer and the total cost is transparent from the beginning. It is the way I am used to it. In Germany, all prices are shown with all tax etc. It is forbidden to present prices without tax. I.e. for me it will be then this way everywhere, when I buy online.

I have not noticed that some people had complained about that. I noticed that people complained about the Trump's claim that the seller would pay for the tariffs, which is simply not true.

And there is in the US apparently a lot of chaos. Rules are introduced without any tools to implement them - and the rules themselves are constantly in change. And imports of small articles in the US appear to be very expensive because of the very high handling fees.

All the reports for 2028 state that the EU's goal is to make IOSS easier to use. I have no idea if that will work, or if using platforms such as eBay and Amazon will remain easier to use. If IOSS remains complicated and expensive for small businesses, that would certainly be problematic (because that would strengthen the large platforms). However, IOSS makes it possible to pay tax (and potentially customs duties in the future) without incurring any handling fees. This would make it easier and cheaper for customers.

IOSS is a way to make easier for customers without changing the basic rules.

Trump claims that he want to bring production back to the US, he propagates protectionism, he want to change the international trade networks. I do not see any similarity in the goals or the approach.
