Home delivery. According to a query on JD.com’s official website, JD Cold Chain uses professional cold chain equipment certified by GSP standards to provide cold chain logistics services that comply with transportation specifications. Consumers place orders and have them delivered to their doorstep, and the entire cold chain process is guaranteed. Cold chain express door-to-door delivery time is 9:00-21:00. At present, the area that JD’s cold chain can cover is limited, and delivery to remote places is unavailable. Only places with cold chain warehouses nearby can enjoy door-to-door delivery, and the number of cold chain warehouses is also increasing.
