Customs Authorities are government agencies responsible for regulating the flow of goods into and out of a country. They ensure that all imports and exports comply with national laws, including tariffs, trade agreements, and safety regulations. Their main functions include inspecting cargo, collecting duties, and preventing illegal activities such as smuggling. These authorities play a crucial role in protecting a nation's economy and security. They work closely with other agencies, such as border control and law enforcement, to monitor and manage international trade. By enforcing regulations, Customs Authorities help maintain fair competition and safeguard public health.
