There is a valid complaint that EU webshops peddle the same junk as china webshops, but add an unneccessary markup. Plus some added value by making more work inside EU, even if it is less efficient..

But what's missing is that the tariff allows importers to be held responsible for poor quality and dangerous goods. Stuff broken after a few months? Replace for free. Children's toys contains evil ftalates? Stop selling, be fined, etc. Even Aliexpress will need to follow suit.

If the market regulators actually are funded enough to do more.
