Custom house

Government office building for import and export of goods

A custom house or customs house was traditionally a building housing the offices for a jurisdictional government whose officials oversaw the functions associated with importing and exporting goods into and out of a country, such as collecting customs duty on imported goods. A custom house was typically located in a seaport or in a city on a major river, with access to an ocean. These cities acted as ports of entry into a country.
