Import duty and taxes are due when importing goods into Thailand whether by a private individual or a commercial entity. The valuation method is CIF (Cost, Insurance and Freight), which means that the import duty and taxes payable are calculated on the complete shipping value, which includes the cost of the imported goods, the cost of freight, and the cost of insurance. In addition to duty, imports are subject to sales tax (VAT), and in some cases to excise, interior tax and a surcharge.
