Tourism Refund Scheme - TRS
If you have items in your checked baggage that you would like to claim for TRS, please ensure before you check in your baggage that you cross to the TRS-branded window in the international terminal forecourt and show the items to the officer so that you may be issued with a validation certificate. Then repack your items, ensuring you keep the receipt and validation certificate on your person, and check in as normal. You will present the validation certificate and receipts at the TRS desk after you pass through passport control.
If your TRS items are on you or in your on carry on luggage, then you only need to show items and receipts as you pass through passport control.
