I'm going to travel to Thailand for about a month. Inbound and outbound flights are through BKK.
What I want to do is a round-trip to Hong Kong for a shopping before leave Thailand. In particular I'd like to buy MacBook and iPhone, since they're much cheaper in HK than in my country.
What concerns me here is Thai customs. As I can see on their site "If you are bringing in with you the items with total combined value more than 10,000 baht, these items are subject to import taxes and duties." 10000 THB is about 285 USD at the moment.
Does it applicable if I'm going to leave Thailand on the same day or in couple of days? Does it matter if items are unboxed?
Another related question is shall I pay duties if I bring my MacBook, iPhone and iPad into Thailand on my first entry? Their total value is probably above stated limit.
Many thanks in advance.
