Restrictions are placed on the import and export of the following items: drugs, firearms and pornography. Allowances are made for the export of genuine antiques, though only with authorisation (arranged through the antique dealer). Leaving Thailand with more than 50,000 baht requires authorisation. Conversely, there is no maximum on the amount of currency a tourist may import, though customs officials may enforce a minimum currency threshold.
All those entering the country are required to fill out a customs declaration document. Duty-free allowances (per person) are as follows: 200 cigarettes, one video camera, three rolls of film and one litre of alcohol.
