The Customs Department was founded when Singapore was the British Empire's
Straits Settlements and later
Crown Colony. Established in 1910 under the name Government Monopolies Department, Customs is one of the oldest tax-collecting organisations in modern Singapore to increase the country's state coffers to help fund national programmes. Revenue collection began in December 1909 when the first import duty was imposed on hard liquors. In 1916, the tariff was extended to include tobacco and cigarettes. The collection of duty on petroleum was introduced in 1934. Motor vehicles are also subject to tax and excise duties. Effective 1 January 2012,
compressed natural gas (CNG) for motor vehicles is subject to tax and excise duty. The department has gone through many transitions, mergers, and re-organizations in the last century under the government of Singapore. The department's responsibilities in securing Singapore's future are affected by worldwide globalization, market forces and changes in laws, tariffs, trading and traveling trends. On 1 April 2003, the department was re-constituted as Singapore Customs - a government agency transferred to the Ministry of Finance of Singapore - providing essential services for revenue collection and enforcement, trade documentation, trade facilitation, and security functions as Singapore’s single authority on customs and trade regulatory matters. On 15 November 2019, the new Customs Operations Command building was officially opened at Bulim Drive off
Jalan Bahar in
Jurong West. This will allow for intelligence, investigation and compliance-related functions to come under the command. On 1 January 2025, Singapore Customs unveiled a refreshed logo. ==Primary roles and functions==
