Although Amazon's delivery is good, if Amazon sellers want to directly connect with Amazon's warehouses, there are both threshold requirements and difficulties in first-way docking. For example, Amazon's warehouses are scattered in more than 100 places in the United States, and it is difficult for even large sellers to separate their products. Sending to so many points; implementing rating access control for sellers, and increasing storage costs have all caused difficulties and obstacles for small and medium sellers on Amazon. Therefore, in addition to the early international log of Amazon warehouses, Dawei also uses its warehouse network to support its international freight and customs clearance to provide Amazon warehouse preparation and transshipment services. Its main functions are as follows:

• Finishing - receiving bulk and loose cargo, unpacking, sorting and palletizing sea containers
• Delivery - according to the customer's instructions, deliver the whole vehicle or less than a load to the designated Amazon warehouse
• Reconditioning - secondary processing of products according to customer needs: reclassification, packaging, labeling
