From there, the package moves through Cainiao's high-efficiency logistics network, ensuring continuous monitoring and rapid transit to its destination country. Once it arrives, it is either handed over to a local Cainiao subsidiary or entrusted to a major national carrier for smooth final delivery. This process guarantees secure, fast, and well-tracked shipping, providing the same level of efficiency as major global retailers.
