In international trade, ports act as crucial gateways for the transportation of goods and people across nations. This section categorizes ports based on their geographical location into three main types: inland ports, which are situated away from the sea and connected via rivers or canals; out ports, which are developed deep-water ports servicing larger ships; and comprehensive ports, which handle a variety of cargo including bulk and general cargo. Examples provided include Manchester and Kolkata for inland ports, and Piraeus for out ports. Understanding the various types of ports enhances our comprehension of international trade mechanisms.
