Wuhan 3C reverse warehouse is the place where JD.COM handles returns, and it is also the spare parts warehouse. When consumers need to return goods, the goods will be sent to this inventory point for processing. JD.COM has a system for maintaining return rules, including two rules: priority return and designated return. If consumers choose to return multiple spare parts warehouses, then each province will configure its corresponding optimal returned spare parts warehouse. And if consumers only open a spare parts warehouse, then all the returns in the country will be designated to return to this only spare parts warehouse.
