10%。 According to market experience and user feedback, the return rate may be limited at around 10%. The main basis of Tik Tok's purchase restriction is the user return rate. Return rate refers to the proportion of goods returned by users after purchasing them within a certain period of time. Generally speaking, Tik Tok's purchase restriction policy is triggered when the return rate of users exceeds a certain threshold. After the return rate exceeds a certain threshold, Tik Tok will restrict the user's account, which means that orders cannot be placed or restricted. Such restrictions are mainly to protect the rights and interests of merchants and maintain the normal operation of the platform. Frequent returns not only cause losses to merchants, but also reduce the trust of the whole trading environment and affect the purchase decisions of other consumers.
