International air express shipping involves customs clearance and transportation by air. The main types include:

Commercial couriers: UPS, TNT, DHL, and FedEx, collectively known as the four major couriers.

International postal express: Such as China EMS, Singapore EMS, Hong Kong EMS, etc.

Dedicated line express: Transportation to foreign countries through air chartering, with final delivery handled by partner companies. Examples include the China-Russia dedicated line, Europe dedicated line, China-US dedicated line, etc.

Advantages of international air express shipping:

Fast delivery: Generally, intercontinental shipments are completed within 1-5 days, and within regions in 1-3 days. Such delivery speed is difficult to achieve with traditional air freight or postal transportation.

High security: Under the international air express shipping model, the entire process is handled within the same company. The operational procedures and service standards are consistent among branch offices. Additionally, internal communication within the same company is more convenient, ensuring better protection for high-value and fragile goods. Therefore, transportation security and reliability are enhanced.

Greater convenience: International air express shipping goes beyond air transportation alone. It is more like a combination of air and land transportation, providing door-to-door services, which greatly benefits customers. Moreover, international air express companies offer convenient online services, allowing customers to track the logistics status throughout the entire journey.

Billing standards for international air express shipping:

In international air express shipping, due to limited cargo space, placing a bulky but lightweight item in the same space incurs additional costs. Therefore, according to international standards, the weight of the shipment is divided into actual weight and volumetric weight.

After packing the items, the dimensions (length, width, height) and weight of the package (or outer packaging such as wooden crates) are measured. In most channels of air express shipping, the billing is based on the higher value between actual weight and volumetric weight. Volumetric weight (in kilograms) is calculated using the formula: dimensions of the outer packaging (in centimeters) divided by 5000.

For example, if the dimensions of the package are length (50 cm), width (40 cm), height (60 cm), the volumetric weight calculated based on these dimensions would be: 50 cm x 40 cm x 60 cm / 5000 = 24 kg (volumetric weight). If the actual weight of the package is 20 kg, the chargeable weight would be 24 kg (volumetric weight). If the actual weight of the package is 28 kg, the chargeable weight would be 28 kg (actual weight).
