The advantage of customs data is naturally to provide a factual basis for foreign trade, after all, this is not an era of relying on experience to do business, and everything must be based on facts.
So the role of customs data (which must be real customs data) is first to understand the foreign market of the product. For example, if a company wants to do foreign trade with a new product, it must first look at the market where the demand for the product is relatively high and how the price is. Then we will take a look at some companies that are interested in their peers, take a look at the market situation of their peers, and then understand their prices and customers. Finally, there are foreign customers that we all pay close attention to. When we see foreign buyers directly, we can contact them directly. However, some of the customs data I know is basically without any contact information, and it's useless to find them. We basically have to rely on ourselves to find them, but the reference price for quantity and price is still quite large.
There must be some drawbacks, but many countries do not have customs data, such as the European Union, the Middle East and Africa, where there is no good data. The market there is still quite envious. And then there are many data companies that provide data that is not entirely fake. Previously, there were still useful data that was reported to have results before buying, but later it was discovered that it was not the transaction details at all. It's too pitfalls. Please be careful not to step on the pitfalls and learn a painful lesson.
