Amazon's first global Smart Hub Warehouse (GWD) has opened in Shenzhen, providing sportswear sellers with one-stop warehousing and distribution services. Leveraging a "warehousing at the source" model, cross-border delivery times can be shortened by up to 7 days, and storage costs reduced by up to 30%. This model supports "small-volume, frequent replenishment," effectively solving the problems of inventory backlog and stockouts in sportswear, and reducing capital tied up costs. Amazon data shows that sellers using GWD have seen a 40% increase in the success rate of new product launches, especially suitable for high-frequency turnover categories such as quick-drying clothing and yoga wear.
