Customs officials are government employees responsible for monitoring and regulating the flow of goods and people across national borders. They ensure that all items entering or leaving a country comply with laws and regulations, including tariffs, taxes, and safety standards. Their work helps prevent illegal activities, such as smuggling and trafficking. These officials inspect luggage, cargo, and vehicles at ports, airports, and border crossings. They may also conduct interviews with travelers to assess the legitimacy of their declarations. By enforcing customs laws, they play a crucial role in protecting national security and the economy while facilitating international trade and travel.
