The Royal Customs and Excise Department previously known as Customs and Bea Department is one of the oldest government departments. It was established in April 1906.

It was set up in 1906 and was then known as The Royal Customs and Excise Department (RCED). RCED is under the Ministry of Finance since 1984.The establishment of the Customs Department was as a result of the introduction of Customs Regulation on imports and exports for the purpose of administrative cost under the control of British Resident.

The role and responsibility of the Customs Department were not only focussed on collection of the imports and exports duties and control of the smuggling activities but also to include financial matters (treasury) following it's unification with the Treasury Department in 1915.

After Brunei Darussalam achieving independent in 1984, RCED had undergone various changes and reformation in line with current development as a result of RCED's committment with the international Customs Organizations such as in ASEAN, APEC, ASEM, WCO and BIMP-EAGA.
