I would like to hi-lite a situation faced by my spouse in her recent visit to Vietnam. She and her group of 6 were stopped after immigration check-out at Ho Chi Minh Airport. The reason - they didn't declare goods bought in Vietnam. From our understanding and information there is no declaration required for goods bought (aka export out?) where the goods are keepsakes and souvenirs. The authority who stopped them threaten them a day or 2 in prison. They were inform that only allowed to purchase goods for own use - example cloth and silks. Even already went for boarding they were called again. In the end they were asked to pay USD50 per bag/luggage which afterwards change to RM50 per person. No receipt were given. The same case happened to most of the Malaysian during that trip on 16 June 2011 to KLIA via Ho Chi Minh Airport.
Upon checking with our local tour operators, there are no such regulation. I hereby would like to seek explanation, except for prohibited items which already clearly stated in Custom regulations, are there items that foreigners need to declare in terms of quantity or amount or prohibited to bring out of Vietnam. Your explanation regarding this matter is highly appreciated and thanking you in advance to clarify this matter since I am planning for another trip to Vietnam soon.
