Upon arrival in Thailand, foreign citizens must hold a valid passport with at least six months validity, a valid Thai visa, and proof on onward travel. However, visitors from ASEAN or Western countries, including most European, Commonwealth, and North American citizens, are not required to have a Thai visa for visits less than 30 days in Thailand.  They will be granted access through Thailand immigration with a 30 Thai visa waiver, provided upon arrival. After such time, a Thai visa extension from an immigration office or a Thailand visa from an embassy or consulate outside of Thailand is required. Immigration policies are subject to change: check with a Thai Embassy or The Ministry of Foreign Affairs (www.mfa.go.th) for the latest information.

Duty Free 

Thailand customs allows visitors to enter Thailand with personal effects, the value of which does not exceed 80,000 Baht, without paying import fees as long as: 1) the items are specifically for personal or professional use; 2) the amount of goods are reasonable; and 3) the items are not subject to restriction or prohibition.  

There are restrictions on the amounts of alcohol and tobacco products; only the following amounts may be transported into Thailand under duty free regulations: 

   * 250 grams of cigars or smoking tobacco, or 200 cigarettes 
   * 1 liter of wine or liquor. 

Prohibited and Restricted Goods The Thailand Customs Department is responsible for stemming the illegal transport of illicit drugs into and out of Thailand.  Consequently, Thailand Customs officials do occasionally ask to search passengers’ bags.  If you have nothing to declare, simply walk through the Green Channel, stopping only if asked to do so by a customs agent. 

If you have goods to declare, you should hand a customs form to the Thailand Customs Department agent at the Red Channel marked “goods to declare”. 

It should be noted that plants and animals, as well as products made from such, may be subject to restrictions and quarantine.

Departure Tax 

International departure taxes are now included in the cost of air tickets when they are purchased from an airline or travel agent.  There are no official domestic departure taxes, although privately owned and operated airports, such as Koh Samui Airport, has levied a small domestic “departure tax” in the past and may still do so depending on their current policies.
