If the purchased goods are placed in the checked baggage, after arriving at the airport, you need to stamp the customs seal at the customs counter first, and then go through the baggage check-in procedures. It should be noted that before the customs stamps, it is necessary to ensure that the tax refund goods are intact and have not been used or opened.
The last step in the formalities is to complete the tax refund. When you finish this procedure at the airport, you will probably have to wait in line, so you must leave enough time. Cash tax refund needs to be queued and settled in local currency, but the advantage is that you can get the money right away. Credit card tax refund is also very common, and the tax refund institution will directly transfer the tax to the registered account, but it will lose a certain handling fee.
