Before the development of cross-border e-commerce, foreign end users can only be achieved through cooperation with foreign retailers or logistics providers, after the development of cross-border e-commerce, the company's goods will be distributed to consumers as soon as possible after arriving in Hong Kong by sea. Because it can directly face foreign end users, it will effectively reduce intermediate links, save costs, and at the same time, it can also broaden the business space and provide services for more merchants. In addition, cross-border e-commerce business also allows enterprises to group multiple orders within a certain period of time into one customs declaration, and regularly declare them in a centralized manner by enterprises or individuals, which not only reduces the cost of enterprises, but also facilitates tax rebates and foreign exchange settlement quickly and conveniently.
