Air cargo is transported only by airplane, while freight includes sea transportation, land transportation and railway transportation. The most suitable transportation method can be selected according to the characteristics of the cargo.

The maximum weight limit for air freight depends on the airline you choose. Generally speaking, each airline has its own regulations and restrictions. Normally, the gross weight of each shipment is between 100 and 500 kg.

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.

Flammable liquids and solids are among the most common prohibited items in air cargo. The reason these items are listed as prohibited is because they can easily ignite, potentially causing a serious fire hazard.

Ocean freight is the most commonly used method of cargo transportation in global trade and is known as the lifeblood of global trade. It excels in transporting bulky cargo and may even be the only option for some cargo that cannot be transported by other means. Maritime transportation has the characteristics of large-scale transportation, wide application range, relatively slow speed, and environmental friendliness.
