How to calculate the freight of general logistics?

Under normal circumstances, the freight is calculated by tons for heavy goods and cubic meters for wet goods. The standard weight-to-foam ratio is = 1:4, that is, 1 ton =4 cubic meters, > = 4 is bubble goods, _4 is heavy goods, _ 1 cubic meter or _300 kilograms of goods are bulk goods, and bubble goods are priced by pieces, each piece is 0.65438.

The dividing line with bubble goods: 1 m3 =300 kg. If heavy goods 1000 yuan/ton, foam goods are almost 333 yuan/cubic meter, and the freight varies from 0.4-2 yuan/kg according to the distance.

The shipper delivers the goods to the place designated by the carrier, and the carrier transports the goods from place A to place B. The consignee should receive the goods at the place designated by place B. This freight is only charged separately.

The carrier picks up the goods from the shipper and then delivers the goods to the destination, but there is no delivery requirement. This freight is the logistics freight plus a small fare.

The shipper delivers the goods to the carrier's location, but requires delivery after arriving at the destination. Freight should be logistics transportation fee plus delivery fee. If the carrier needs to provide unloading, it should be indicated on the transport bill, and the corresponding unloading fee and upstairs fee should be added. The freight rate of special goods is higher than that of ordinary goods.
