Practical advice
Declare cash, traveler's cheques, or monetary instruments above the local threshold to Thai Customs on arrival or departure. Use the dedicated currency-declaration channel; undeclared amounts above the threshold are subject to seizure and an administrative fine of 25-50% of the undeclared sum.
