A.We already paid tax to our logistics when keep all goods stock in Poland in advance,so after customer placed order,we can ship directly to customer via our Poland warehouse.
B.If E.U stock sold out & stock data not updated,we need to ship new stock from China to Poland via railway,you can choose that:
1.Wait for our warehouse stock arrive Poland,then can proceed order.
2.We ship goods directly to E.U customer by railway DDU channel.
