Calculation of freight has a very important relationship with the traders, for example, a transaction in accordance with CIF or C & F price of the transaction, whether the freight is how much the price structure account for much in the proportion of cost accounting for the export side is at stake. Even with the FOB price of stock at the time, master ocean freight information, the terms for the calculation of the difference between the various price, good parity work is also very important.

Freight is based on the designated freight liner's table calculation. At present, the national shipping companies of the tariffs set by the table, its format is not exactly the same, but the basic content is relatively close.

Price list shipping companies, generally based on the different types and nature of goods, as well as ease of loading and storage, but divided into several grades. In the same route, as a result of goods at a different level, shipping companies charge a basic rate is different. Thus, the commodity level and the level of freight a great relationship.

Second, the freight calculation standards vary, for example, generally based on the weight of heavy goods received tons of freight, light Paohuo-ton total income according to size, and some high-value goods by a certain percentage of FOB value of total income, some companies by a mixture of total income, for example, press the weight tons, or tons of revenue size, and then add a number of ad valorem freight costs, reflected in the tariff table is:

1, by weight of tons of income, known as the weight of tons, the table set out in "W", on a per tonne or per long ton unit for calculating.

Second, by cargo volume in income, known as the size of t, the table set out in "M", generally based on 1 cubic meter or 40 cubic feet for the size of t as a unit.

3, by volume or weight, calculated from the ship choice, the table as a "W / M".

4, according to the FOB value of goods a percentage of total income, known as the ad valorem freight (Ad Valorem), the table set out for the Ad Val, or AV.

五. Mixed standard terms according to income, such as W / M plus AV and so on. Namely, by weight tons, or size plus the ad valorem freight tons. In addition, there are some goods are by the piece (per unit) or head (per head) total income, the former, such as vehicles, the latter, such as live animals. For bulk commodities such as grain, ore, coal and so on, due to traffic large, lower prices of goods, easy loading and unloading and other reasons, shipping companies in order to fight for supply that can be agreed upon with the owner of freight.

According to calculation of freight tariff table is a relatively complex task, not only familiar with the basic content of tariff tables, but also need to work carefully in the calculation of freight rates, in addition to routes and commodities, according to grade, start with a basic rate (Basis Rate) calculated the basic freight, and also to identify various additional costs of the project and will require a surcharge of 11 spending account.

More of these additional cost items, for example, due to the different products, the port is different from, or other reasons, there may be additional charges, but also keep abreast of its movements.

Surcharge to the following categories:

First, characteristics of different commodities increase the surcharge, such as overweight surcharges, long surcharges, washing fees.

Second, they monitor the situation and increase the port surcharge, such as port surcharges, port congestion charges, the election of Hong Kong costs, direct surcharges.

Third, due to other reasons, a temporary increase in the surcharge, such as fuel surcharge, depreciation surcharges.

Fact surcharge under various names, far more than the above-mentioned these types. It is worth noting that some additional costs, such as port congestion charges, accounting for a large percentage of freight, compared with basic freight, ranging from 10% to as many as up to 100%, even more than twice. Thus, in the calculation of freight rates can not be ignored in the calculation of the surcharge.

To give one example. A round of the shipment from Shanghai, 10 tons of a total of 11.3 cubic meters egg products to the United Kingdom Plymouth Harbor, sailing, all freight how much? Solution: The investigation of goods classification table we can see that egg products are 10 to calculate standard is W / M; check China - the Euro-Mediterranean route table of the 10 grade rates for the basic rate of the goods 116 yuan / ton; The investigation additional rate sheet we can see that Hong Kong direct surcharge of Plymouth, each accounting for 18 per ton; fuel surcharge of 35%. Therefore, all freight is: F = (116 +116 X35% +18) X11 = 1920.60 Yuanben example, 10 tons of egg products by the investigation of goods classification table, the calculation of the standard is W / M, whichever is greater as the calculation of the standard, then the size is 11 tons.
