Customs data itself is a good channel to obtain information, and importers and exporters' information is an important supplement to foreign trade development and maintenance customers. Through customs data, we can directly understand the information of purchasers, suppliers, transaction dates, products, frequency, quantity and price in different regions. In view of the regulatory and policy reasons of various countries, the data of all service providers in the market are basically based on the data of North America, South America, Europe, Asia and other countries. In the process of developing customers in foreign trade, it takes a lot of time to find, screen and validate customers. Even so, the exact customer may not be found. On the other hand, writing an effective development letter requires further investigation of the customer's background, which increases the difficulty to another level. After a lot of hard work to close a deal, you still have to worry about protecting your customers, but the painful thing is that you often can't find a starting point and have to avoid being poached by competitors. In view of this situation, the International Foreign Trade Company provides users with customs data services and 40 million real import and export information. We use big data to analyze and study user needs, clean, classify and merge hundreds of millions of original customs bill of lading data, and help users improve the efficiency of development and maintenance customers from multiple scenarios.
