Importing from China to Denmark
Im from Denmark so I will make a short explanation on how to manage customs and taxes on imports from China and especially Aliexpress. You will probably be able to make use of this, no matter what country you live in.
In Denmark you have to pay 25% vat if you buy for more than around 14$ (80 DKK). In addition to that fee, all companies who do the customs declaration claim a fee ranging from 25-30$ ( 150-180 DKK). This makes cheap products rather expensive. Normally the Aliexpress sellers write a low value on the commercial invoice for the products send with HK- or Chinapost. Many times the products will still be checked in Danish customs upon arrival (Post Danmark manages that). Clothing tend to be the easiest to get through without paying any vat or other fees, even if opened, they dont bother herrassing you.
If they do, you have to send them a product receipt and a link to the place you bought it. If the products are counterfeit, nothing really happens as long as it is for your own use.
