# How To Calculate The Reasonable Number Of Products Installed In The Cabinet In Foreign Trade Busines

In the actual foreign trade business, it is very important to calculate the packing quantity and container quantity of products, especially in the case of diversified product packaging types and container types, then how to calculate the most reasonable container quantity? Let’s have a look! First of all, let's have a look at the container. What are the factors that determine the volume of the product? Conventional loading volume The following types of containers are commonly used, including 20 feet container, 40 feet container, 40 feet tall container, 45 feet tall container, etc. Different cabinet, its size and size are not the same. Usually when we pack a container, the main consideration is the loading volume of the container. The content volume and volume comparison of various containers are shown in the following figure: From the internal dimensions, we can calculate the maximum theoretical capacity of the corresponding container, that is, the loading volume. However, in the actual loading process, it is often impossible to load so many goods, which involves the utilization of the content space of the container. Normally, except for materials such as air and liquid that can fill the entire volume of the container, other goods can only achieve a volume utilization rate of 85% -90% at most. So let's calculate that 85% to 90% of the shipping volume of the container is between 28.1 and 29.7. In fact, the quantity of most goods loaded depends on the size and shape of the boxes. Factors affecting the number of containers In actual foreign trade business, the theoretical loading volume of different cabinet types is different from the actual normal loading volume. Normal loading volume of various types of containers: 20-foot flat cabinet, the loading volume is generally 28 cubic meters; 40-foot flat cabinet, the loading volume is generally 58 cubic meters; 40-foot high cabinet, the loading volume is generally 68 cubic meters; 45-foot high cabinet，the loading volume is generally 68 cubic meters. Normally, different cabinet types basically have a theoretical average value in the foreign trade industry, and the actual number of boxes depends on the following three main factors: First, the volume of a single carton is large; Second, the shape of the carton; The third is the number of varieties of goods. If there are more varieties, there may be many types of outer box sizes, which will also have a certain impact on the actual packing volume. Then let's take a look at the issues that need to be paid attention to and recommendations for loading containers in different cases. Precautions and suggestions for cabinet loading In the first case, the cargo boxes packed in the cabinet are small in size and single in variety. It is recommended to calculate a little more for a single variety of goods in a whole cabinet. For example, a 20-foot flat cabinet can be installed to 28.5 cubic meters; a 40-foot cabinet can be installed to 58.5 cubic meters. The smaller the volume of the box is, the higher the space utilization is. In the second case, the loaded cargo boxes are large in size and single in variety. Such a single large box needs to be cautious when calculating estimates. Establish a larger amount of container loading, for example, a 20-foot flat cabinet can be counted as 25 cubic meters; a 40-foot cabinet can be counted as 54 cubic meters. In practice, this treatment is generally more guaranteed. There will be no situation where the goods cannot be loaded, resulting in a backlog of warehouses and the goods are deformed / damaged. It is also important to note here that when the containerized goods are large boxes of a single variety, they cannot be generalized. We have to look at the shape of the carton. Among them, the closer to the square box, the lower its space utilization is. A rectangular box, although large in volume, has a low value on a single side, and when the box is nearly flat, its space utilization rate is higher than that of a square box. When loading, you can lay it horizontally or sideways to fill the remaining loading space as much as possible. In the third case, multiple types of goods are mixed. Because there are many kinds of box sizes and different kinds of box shapes, it depends on the situation. One is that the number of small boxes is large, and the packing amount can be calculated slightly. The other is that the number of large boxes is large, and the size is also large. Actual loading is a waste of space, so it is recommended to leave a little more margin and count less.
