Clearance Procedures for a Temporary Import of Personal Vehicles

- The importer/agent places the cash deposit or bank guarantee at a Cashier Office.
Deposit of Guarantee

However, for a temporary import of motorcycles via the Bangkok Port Customs Office and the Suvanabhumi International Airport Cargo Clearance Customs Office, the importer is allowed to offer himself as a guarantee.
- In case where the importer is unable to deposit a guarantee either in a form of a cash deposit or a bank guarantee, he/she may request the embassy to issue a letter to Customs granting approval of the importer s self-guarantee.
- The amount of a cash deposit and a guarantee calculated by Customs is determined on the basis of all liable taxes and duties to be paid to Customs.
- The importer/agent presents evidence of deposited guarantee to Customs.
- Customs inspects the vehicle and personal belongings, then, returns one copy of the Simplified Goods Declaration to the importer/agent. Please note that the importer is required to retain the copy of the Simplified Goods Declaration and return it to Customs upon exportation.
