@Client:45820162 If you buy products that are shipped from outside the European Union, you have to know that they can be checked and import billing in accordance with applicable regulations. The ordered shipment may be subject to customs control. The result of such control may be the necessity to pay VAT and customs duties. More information you can find here (unfortunately full text is only in Polish).
I think it's up to your country policy to pay or not the shipment from HK 🙂
We don't know you are English, German or Japanese, so it's up to your country not ours 🙂
Allegro it's not a seller, it's a marketplace.
