A Customhouse is a government office located at a port, airport, or border crossing where customs officials oversee the clearance of imported and exported goods. Historically significant in major trading cities, customhouses serve as administrative centers for collecting duties, verifying documentation, and enforcing trade regulations. They may also house inspection facilities and bonded storage areas. Today, while many processes are digitalized, the term remains in use to describe official customs premises responsible for regulatory control of international cargo movements.
