Tips for Travellers
DO NOT BE TEMPTED TO CARRY GOODS FOR OTHERS
You will be held liable if the goods are, or contain prohibited, controlled, restricted or taxable items.
THE RED AND GREEN CHANNEL SYSTEM
The Red and Green Channel System is a self-elective system. The decision as to which channel to use is, therefore, entirely up to the traveller. By electing the Green Channel, you are deemed to declare that you do not have anything to declare to the authorities. It is an offence under the law to proceed to the Green Channel with taxable goods which exceed the GST/duty-free allowance or any goods which no GST/duty-free allowance is granted.
A TRUE AND COMPLETE DECLARATION
Making an incorrect declaration is an offence under the law. The offender may be fined up to $5,000. Please therefore declare any goods which you think may fall under the category prohibited or controlled and any item in excess of your GST/duty-free concessions or any item that is not granted GST/duty-free concession. If in doubt, always refer to the Red Channel.
BAGGAGE EXAMINATION
Under the law, you are required to produce, open, unpack your baggage for Customs examination and to repack it thereafter. You may be directed to the X-ray machine for scanning of your baggage. Please declare any duitable/taxable goods or goods in excess of your GST/duty-free concession to the officer thereat before your luggage is scanned.
BRINGING IN MEDICINE FOR PERSONAL USE
If you need to bring in medicines (especially sleeping pills, depressants, stimulants, etc.) for your physical well-being while travelling, you must possess a physician’s prescription certifying so.
PETROL THREE QUARTER TANK RULE
Singapore registered cars must have at least ¾ tank of petrol when departing Singapore. Failure to do so constitutes an offence.
CONTROLLED AND RESTRICTED ITEMS
Certain goods are allowed entry into Singapore only when you produce the import permit or authorisation from the relevant authorities. If you do not have the import permit or authorisation, the item will be detained and referred it to the relevant authority for approval.
Enjoy your travel.
