1. Tax-free goods in checked luggage
If your tax-free goods are in a suitcase that you will be checking in, please go to the customs office before you check in (arrival level/level 0). You can check in your luggage containing tax-free goods after you have clarified the formalities with the customs. You may be accompanied by customs officers to the baggage return so they can ensure that the good are actually physically exported.
2. Tax-free goods in hand luggage
If your tax-free goods are in your hand luggage, first check in your checked baggage and then go to the customs office (arrival level/level 0) with your hand luggage.
The customs office can be found on the arrivals level/level 0, to the left of the exit in the baggage return hall. You will receive an export confirmation from the customs office two hours before departure. The goods are randomly compared there with the accompanying invoices and certificates, stamped upon compliance with and fulfilment of all conditions, and returned to you.
