ICA officers deployed as cargo and baggage examination officers are empowered under the Customs Act (Cap 70) to search people and conveyances at all ports of entry in Singapore.. They can then seize any controlled items or contraband found before referring them to the appropriate Controlling Agency such as Singapore Customs or the Central Narcotics Bureau. The most common contraband are duty-unpaid cigarettes and tobacco products due to the high duties imposed on them. Other examples include narcotics, replica firearms, wild animals and unlicensed medicine.
