If you’re entering Hong Kong with e-cigarettes containing nicotine, you’ll need a medical prescription indicating that they’re for personal use. If the e-cigarette is nicotine-free and for personal use, no medical prescription is needed. So travelers, be aware: you should either show proof that the e-cigarette is without nicotine, or show prescription. Nicotine is considered a Part 1 poison in Hong Kong, and the possession of a nicotine e-cigarette without a prescription faces a penalty up to $100,000 fine and 2 years’ imprisonment.
This order follows recent efforts by officials, headed by Secretary for Food and Health Professor Sophia Chan, to step up on e-cigarette control and its possible carcinogens. Take note that in Hong Kong, cigarette smoking, including e-cigarettes, is banned in no smoking areas, including all indoor public areas, and some outdoor areas like school campuses and parks.
Other entry requirements remain unchanged; US citizens can visit Hong Kong for up to 6 months without a visa. If you visit mainland China via Hong Kong, you must obtain a Chinese visa before arrival at the Chinese border.
