Factory-level sellers, brand owners, and online sellers.

Factories have production capabilities and even certain R&D capabilities, and they generally focus on making their own products;

Brand owners hold brands, especially overseas brands, and look for factories to process hot-selling products and sell them overseas based on market conditions and the categories to which their own brands belong;

Online sellers generally source their goods from online, and they do not accumulate inventory too much, and only purchase when an order is placed. There are many sources of goods for sellers, mainly concentrated in two categories. The first category is domestic e-commerce websites, such as Taobao, 1688, JD.com, Amazon China, etc.; the second category is e-commerce websites that mainly do distribution, such as Alibaba, Banggu and other bulk sales platforms.
