General freight calculation formula:

a) When the item to be delivered is actually larger than the volume, the freight calculation method is:

First freight + (weight (kg) × 2-1) × continued freight

For example, if a 7kg product is calculated based on the first weight of 20 yuan and the additional weight of 9 yuan, the total freight is:

20＋(7×2-1)*9=137 (yuan)

b) When the actual weight of the item to be delivered is small and the volume is large, the freight shall be charged according to the volume standard, and then the total freight shall be calculated according to the above formula. The volume formula is as follows:

Regular items: length (cm) × width (cm) × height (cm) ÷ 6000=weight (kg)

Irregular items: the longest (cm) × widest (cm) × highest (cm) ÷ 6000=weight (kg)

c) International shipments sometimes add fuel surcharges

For example, the fuel surcharge at this time is 9%, and the result of formula (a) needs to be added: freight × 9%

Fuel surcharges are generally discounted with freight
