①When the actual weight of the items to be delivered is greater than the volume, the calculation formula for international express delivery is: first weight freight + (weight (kg) x2-1) x additional weight freight
For example: 5kg of goods are calculated based on the first weight of 150 yuan and the additional weight of 30 yuan, the total freight is: 150 + (5×2-1) x30 = 420 yuan
②When the actual weight of the items to be delivered is small and the volume is large, the freight needs to be charged according to the volume standard, and then the total freight is calculated according to the above formula. The formula for calculating the volume is as follows:
UPS, DHL, TNT, Fedex: length (cm) x width (cm) x height (cm) ÷ 5000 = weight (kg)
③International express delivery sometimes adds a fuel surcharge.
For example, when the fuel surcharge is 9%, it is also necessary to add the result of formula ① (i.e. the calculation formula for international express delivery): freight x 9%
④Hong Kong and China Post registered parcel freight.
This method generally includes basic freight, handling fees, registration fees, etc.
