The worry-free logistics service of the AliExpress platform, including standard logistics and priority worry-free logistics, provides users with relatively guaranteed services. Among them, if the goods are lost during transportation, the platform will be responsible for handling related after-sales issues.

The determination of whether an item is lost is mainly handled by the AliExpress platform customer service and Cainiao customer service. When a merchant chooses the worry-free logistics service, if the goods are lost during transportation, the merchant needs to file a complaint through the system within the corresponding time limit according to different complaint items.

It is worth noting that merchants who choose the worry-free logistics service do not need to worry about the losses caused by lost items, because all expenses will be fully borne by the platform. For example, the maximum compensation limit for worry-free standard logistics is 800 yuan, while the maximum compensation for priority worry-free can reach 1,200 yuan. This service not only reduces the risks of merchants, but also provides consumers with a better shopping experience.
