In those days, dated back to the reign of King Rama IV, a “Tax House” was established to collect Customs duties and taxes on imported goods. Later, the Government in the reign of King Rama V recommended a tax collection system which was first governed by the public sector. The Customs House was later founded and accountable for the collection of all kinds of duties and taxes. The House is presently known as the Customs Department.

      Since its founding, the key role of the Thai Customs Department has been collection of duties and taxes used as national incomes. Now new roles and functions are emerging and long term plans to meet new objectives are being set. The Department, besides maintaining the former roles and functions, has come to a turning point with need to provide faster and better service to public. Emphasis on the export promotion and the need to adhere to the commitments and obligations under international agreements effect the overall structure and administration of the Department. This leads to restructuring and attempts to achieve its new goals.
