The term "Custom House" refers to a government building where customs duties are collected and where goods are inspected before entering or leaving a country. These facilities play a crucial role in international trade by ensuring that all imported and exported items comply with local laws and regulations. In many countries, including the United States, Custom Houses are often located near ports or borders. They serve as a hub for customs officials who assess tariffs and enforce trade laws. The architecture of some historic Custom Houses can also be significant, reflecting the cultural heritage of the area.
