As for the taxation part of your comment that is again an incorrect statement in fact it’s categoriclaly false.
If I as say a Brazillian company want to sell goods to an EU resident I do not perform any tax collection other than the local taxes in my country.
In fact it likely means that I can forgoe some local taxes like VAT or sales tax due to export.
You as the customer are obliged to pay all taxation related to this purchase which is usually paid when the item clears customs as the customs duty.
The only cases when one would collect tax on behalf of another country is when there is an explicit tax agreement to do so and process to support it. This is extremely rare and usually only happens within shared customs unions.
As a non-EU entity I legally can not collect VAT on behalf of EU customers because I have no way of paying that tax on their behalf.
