Freight is calculated according to the tariff table specified by the liner companies. At present, the freight table formulated by the national shipping companies, its format is not exactly the same, but its basic content is relatively close. Secondly, the calculation standard of freight is not the same, for example, heavy cargo is generally charged by weight tons of freight, light throw cargo is charged by foot tons, some high-value commodities are charged according to a certain percentage of the FOB value of the goods, and some commodities are charged according to a mixed approach, for example, the first by weight tons or foot tons, and then add a number of ad valorem freight rates, which are shown in the tariff table as follows: First, by weight tons, called weight tons, the table states "W", calculated per metric ton or per long ton. Second, according to the volume of goods, known as the foot of tons, the table specified "M", generally 1 cubic meter or 40 cubic feet for a foot of tons as a unit of calculation. Third, according to the volume or weight, by the ship's choice and calculation, the table is listed as "W / M". Fourth, according to a certain percentage of the FOB value of goods charged, known as ad valorem freight (Ad Valorem), the table is listed as AdVal or A.V.. V. Charged according to a mixed standard, such as W/M plus AV. That is, by weight tons or size tons plus ad valorem freight. In addition, there are some commodities are charged by piece (per unit) or head (per head), the former such as vehicles, etc., the latter such as live animals. For bulk commodities, such as grain, ore, coal, etc., due to the larger volume, lower prices, easy to load and unload, etc., the shipping company in order to fight for the source of goods, can be agreed with the owner of a separate tariff. Calculation of freight according to the tariff table, is a more complex work, not only need to be familiar with the basic content of the tariff table, but also need to work carefully, in the calculation of freight, in addition to routes and commodities in accordance with the level of the first according to the basic rate (Basis Rate) to calculate the basic freight, and then also to find out a variety of surcharges on the project, and need to be spent on surcharges one by one to be calculated. There are many surcharges, for example, surcharges for different commodities, different ports, or other reasons, and you should keep track of the changes in these surcharges. Surcharges are generally of the following types: 1. Surcharges due to different characteristics of commodities, such as overweight surcharges, extra-length surcharges, and cabin washing fees. 2. Surcharges due to different conditions of ports, such as port surcharges, port congestion charges, port selection fees, direct shipping surcharges, and so on. Surcharges added temporarily due to other reasons, such as fuel surcharge, depreciation surcharge, etc. In fact, there are many kinds of surcharges, far more than those mentioned above. It is worth noting that some surcharges, such as port congestion charges, account for a large proportion of freight, compared with the basic freight, as little as 10 percent, or up to 100 percent, or even more than twice. Therefore, in the calculation of freight, can not be ignored in the calculation of the surcharge. An example is given. A ship from Shanghai shipment of 10 tons, *** counting 11.3 cubic meters of egg products, to the port of Plymouth, England, requires direct shipping, all freight is how much? Solution: After checking the cargo classification table can be seen, egg products is 10, the calculation standard is W / M; check China - Europe Mediterranean route class rate table of 10 cargo basic rate of 116 yuan / ton; After checking the surcharge rate table can be seen, the Plymouth port direct shipping surcharge, per billable ton for 18 yuan; fuel surcharge of 35%. Therefore, all freight for: F = (116 + 116 X 35% + 18) X11 = 1920.60 yuan In this example, 10 tons of egg products by checking the cargo classification table, the calculation of the standard is W / M, take the larger of them as the calculation standard, it is 11 feet of yardage tons
