According to the express delivery company's mailing time statistics, the goods purchased from JD.com and Taobao are expected to be delivered to Hainan within 2-7 working days, depending on the distance and specific express delivery methods.

Among them, SF Express has a shorter delivery time, generally delivering within 2-3 days; other express delivery companies such as Yunda, Zhongtong, and Postal Service take 3-7 days. Due to the complexity of express delivery services, the specific delivery time needs to be inquired according to the order status. It is recommended to pay attention to express information and logistics updates when purchasing, and plan the delivery time in advance.
