The Preferred Warehouse is an important part of the infrastructure of the cross-border logistics supply chain. It can be regarded as the "forward warehouse" of the cross-border logistics route, and is usually set up near the domestic customs clearance port. The Preferred Warehouse can provide "full logistics trusteeship" services for merchants. Merchants only need to prepare the goods here, and the subsequent delivery, customs clearance, and fulfillment will all be completed by Cainiao and AliExpress.

Compared to merchants shipping by themselves, Preferred Warehouse delivery can save more than 20% of warehouse rent and labor costs. In addition, because the Preferred Warehouse is located in China, the stocking cost will be much lower than that of overseas warehouses, which can greatly reduce the financial pressure on small and medium-sized merchants. Goods from the Preferred Warehouse can be shipped to more than 200 countries around the world. Compared with goods in overseas warehouses, the coverage is also wider, which is particularly suitable for testing new products and stocking potential explosive products.
