I have changed the title of this thread to "Importing Nepenthes into Malaysia from Singapore" instead of "The Convention on International Trade in Endangered Species" to better describe this thread.
To find out more about CITES you can check out the article in Resources Page on the homepage
here.
To find out about importing plants from Singapore to Malaysia, check out the articles in the Resource page
here and
here. I am not sure if what hongrui says about the laws is an update to what is in the archive. If it is I will need to update the article.
Please note that there are penalties if you are caught breaking the law and please remember that this is an open forum. Hope everyone understands the seriousness of this matter and that PetPitcher does not encourage unlawful behaviour.
