1. Charging weight of single shipment <20KG: initial weight: 0.5KG, additional weight: 0.5 KG, if the shipment is less than 0.5KG, charge as 0.5KG
2. Charging weight of single shipment≥20KG: minimum charging weight: 1KG, if the shipment is less than 1KG, charge as 1KG
3. Charge by the volumetric weight or the actual weight, whichever is higher, the volume coefficient is 5000, volumetric weight KG=weight*width*height(cm)/5,000
