A Customs House is a government building where customs duties are collected and where goods are inspected when entering or leaving a country. It plays a crucial role in international trade by ensuring that all imported and exported items comply with local laws and regulations. Customs officials work here to assess taxes and prevent illegal goods from crossing borders. These buildings often serve as historical landmarks, reflecting the architectural styles of their time. Many Customs Houses are located near ports or borders, facilitating the movement of goods. They may also house offices for various government agencies involved in trade and security.
