In international shipping, container ships, bulk carriers, tankers and ro-ro ships are the most common types of cargo ships, and their carrying capacity ranges from several thousand tons to hundreds of thousands of tons.

Legally and technically, shippers can choose to ship goods independently without using a freight forwarder. That is, companies or individuals can be responsible for all aspects of the goods, such as transportation arrangements, document processing, customs clearance, etc.

In the process of international cargo transportation, goods will go through complex logistics links, including loading and unloading, warehousing, customs inspection, navigation or flight, etc. These links are full of unpredictable risks, and cargo insurance exists to prevent these risks.

The maximum size of standard air freight is 2.44 x 3.18 meters (96 x 125 inches). This size limit is to ensure that the goods can be safely loaded and transported and can pass through the door and cargo space smoothly. Goods exceeding these dimensions require additional arrangements and handling.
