Arrive 2 hours in advance and follow the signs for “Detax / VAT refunds / Customs” before checking-in any luggage.
If you are departing from France or Belgium, you do not need to print your tax free form as all the international airports, rail stations and sea ports have electronic validation means.
Simply scan the tax free form barcode from your phone at a self-service kiosk or see a customs officer on duty who will validate the refund document electronically on their terminal.
Make sure to have all your shopping still unused and in its original packaging as listed on the tax-free form.
Customs will invalidate the entire refund if you part consume or fail to show any of the items listed on your tax form.
