If you, or friends of yours, are planning on visiting South East Asia (and I highly recommend it) please be aware that there is no duty-free allowance for tobacco or alcohol if you are coming into Singapore from Malaysia. That means ‘zero’, ‘nada’, ‘niente’, ‘none’!
A few days ago our bus was delayed because some young backpackers were trying to bring alcohol into Singapore from Malaysia. We ended up leaving them at the border crossing in the middle of the night. I was reminded of an incident a few months ago when our bus was delayed because a middle-aged woman thought the open package of cigarettes she was carrying did not apply to the NO duty-free allowance law.
I have travelled with Singaporean friends who threw away their cigarettes before going through immigration. Trash receptacles are provided. Although most countries allow for some tobacco products to be imported without duty, Singapore does not. Some alcohol can be imported without duty but NOT from Malaysia. It doesn’t matter where you purchased the alcohol if your last port of departure was Malaysia.
Wishing everyone safe travels!
