Entrepôt
port, city, or trading post where imported goods are stored or sold to be exported again / From Wikipedia, the free encyclopedia
An entrepôt is a trading post where merchandise can be imported and exported without paying a tariff. This is often at a profit. Sometimes it is more convenient to sell to an entrepôt than to travel long distances along a trade route. The entrepôt sells the goods at a higher price to others travelling the rest of the route. In modern times customs areas have largely made such entrepôts obsolete.
This type of port should not be confused with the modern French use of the word entrepôt meaning warehouse.
