Take note of Singapore Customs and Prohibited Items as the country has very tough laws with regards what you can and cannot bring in. There is a mandatory death penalty for trafficking (that includes bringing in, even if it is found within your urine sample) controlled drugs.
The following are items which you must not bring into Singapore:
Controlled drugs and psychotropic substances.
Liquors and cigarettes marked with the words "Singapore duty not paid"
Chewing tobacco and imitation tobacco products.
Chewing gum.
Any form of firearms, any imitation firearm, any toys looking like firearm, even cigaratte lighters that look like pistols.
Endangered wildlife and things made from them.
Firecrackers.
Obscene articles and publication in any form.
Pirated software, DVDs and music CDs.
Seditious and treasonable materials.
You can bring in food items such as chicken, seafood and beef up to 5 kg for your own consumption, above which you need a permit. Medicine that require a prescription under Singapore laws must be accompanied by a doctor's prescription. If you are on medication, it is best to bring along your doctor's prescription.
Dear visitor, thank you so much for reading this page. My name is Timothy Tye and my hobby is to find out about places, write about them and share the information with you on this website. I have been writing this site since 5 January 2003. Originally (from 2003 until 2009, the site was called AsiaExplorers. I changed the name to Penang Travel Tips in 2009, even though I describe more than just Penang but everywhere I go (I often need to tell people that "Penang Travel Tips" is not just information about Penang, but information written in Penang), especially places in Malaysia and Singapore, and in all the years since 2003, I have described over 20,000 places.
While I try my best to provide you information as accurate as I can get it to be, I do apologize for any errors and for outdated information which I am unaware. Nevertheless, I hope that what I have described here will be useful to you.
