Custom visa

On arrival at Thailand Immigration and Customs

Upon arrival in Thailand, foreign citizens must be in possession of a valid passport with a validity of at six months, a valid Thai visa and proof of onward travel.

Securing a visa on arrival in Thailand

The visa on arrival rule allows passport holders of about 19 countries to enter Thailand provided they meet the following requirements:

  • The visit should strictly be for tourism purposes.
  • The traveller must have a confirmed return ticket showing that he/she will be flying out of Thailand within 15 to 30 days of entry. Open tickets do not qualify in this situation. Travelling overland out of Thailand by train, bus, etc., to nearby countries like Cambodia, Laos, Malaysia (including en route to Singapore) and Myanmar is not accepted as proof of leaving Thailand.
  • When entering Thailand, you may be asked to show the flight ticket of your return journey within the stipulated period of 15 to 30 days. If you are unable to do so, you are most likely to be refused entry into Thailand.
  • Tourists are also required to provide proof to show that they have funds of a minimum of 20,000 Baht per person, during the visit to Thailand.

Declarations and Allowances

Duty Free

Thailand customs allows visitors to enter Thailand with personal effects, the value of which should not exceed 80,000 Baht, without paying import fees as long as:

  • items are only for personal or professional use;
  • amount of goods are reasonable; and
  • items are not restricted or prohibited

There are certain restrictions on the amount of alcohol and tobacco products that may be transported into Thailand under duty free regulations:

  • 200 cigarettes or 250 grams of cigars or smoking tobacco
  • 1 litre of wine or liquor

Prohibited and Restricted Goods

The Thailand Customs Department is responsible for halting the illegal transport of illicit drugs in and out of Thailand.  As such, Thailand Customs officials do frisk the luggage of passengers at the airports.  If you have nothing to declare, you can simply walk through the Green Channel, stopping only if asked to, by a customs agent.

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

Please note that plants and animals, as well as products made from them may be subject to restrictions and quarantine.
