Customs agents are government officials responsible for enforcing laws related to the import and export of goods. They work at borders, airports, and seaports, inspecting cargo and luggage to ensure compliance with regulations. Their duties include collecting tariffs, preventing smuggling, and ensuring that prohibited items do not enter or leave a country. These agents play a crucial role in protecting national security and public health. They also help facilitate legitimate trade by ensuring that businesses follow the rules. Customs agents often collaborate with other agencies, such as the Department of Homeland Security and Border Protection, to maintain safety and security.
