>Try this as experiment - try to buy something like precision dowel pins from Poland or DOLD Mechatronik with shipping to Greece, Bulgaria or Romania vs the same thing from Aliexpress or Temu. Chinese costs are cheaper even if they have to fly here.
This is an awful experiment. Only consumers care about delivery costs on deliveries like these, and what you're looking at are explicitly not goods aimed at consumers.
Okay. Then buy pizza oven from Italy and see how shipping costs are 60% of the price of the oven.
Anyway - you seems to misunderstand. If transporting something from Shenzhen to Franfurt is cheaper than transporting the same thing from Krakow to Thessaloniki - means that EU has fucked up royally in its main mission - to facilitate movement of goods. WE have ungodly patch of local carriers and courier companies and a lot of friction in every kind of intra eu goods movement.
