Promote electronic manifest systems and real-time tracking technology to ensure real-time sharing of cargo information around the world. This helps reduce information lags and improve the responsiveness of freight services.

Door-to-door air freight is an all-inclusive logistics service that covers all transportation links from the departure point of the goods (such as factories, warehouses) to the final destination (such as customers or retail stores).

Air freight rates fluctuate according to the time of year and the departure and destination countries. For popular routes such as China to the United States, as of May 24, about $4.5 per kilogram of cargo was paid. This means that air freight costs are about $4,500 per ton.

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.

Customs inspection can ensure that the goods do not contain prohibited or restricted items. These items may cause harm to the safety, health or environment of the destination country and therefore need to be intercepted and processed.

The disadvantages of air transport are mainly: high cost, flight delays or cancellations, need to pay taxes and surcharges, need to pay fuel and currency surcharges, and last mile problems.

Express services usually provide the fastest delivery and may take 1-3 days. Air freight is a fast method of international freight, usually taking 5-10 days. Ocean shipping usually takes longer and may take 20-45 days or even longer.

Cargo usually refers to items transported by various means in commercial trade, including sea transportation, air transportation, land transportation, etc. Freight mainly focuses on the transportation method and process of cargo, including the loading, transportation and unloading of cargo. Freight also involves cargo logistics planning, route selection and cargo tracking. In addition, Freight also has direct contact with the financial aspects of cargo transportation, such as freight calculation and insurance.

The three main types of freight are air freight, ocean freight, and trucking. Air freight is the fastest way to ship, sea freight takes longer, and trucking offers flexibility. Each method has its own characteristics and advantages, and plays different roles in different scenarios.
