The length of Alibaba's after-sales time depends on the order type and product category. For ordinary orders, Alibaba provides 15 days of worry-free after-sales service, during which buyers can apply for a refund or exchange.

For virtual goods, such as software or services, the after-sales time is 7 days. For special goods, such as customized goods or perishable goods, the after-sales time may be shorter. The specific after-sales time will be clearly marked on the product details page, and buyers should check it carefully before purchasing.
