A good commodity means that the commodity can maintain its original quality and function, including the commodity itself, accessories, attached trademark tags and instructions for use. The customer opens the package of the goods based on the inspection needs, or makes a reasonable and appropriate trial to confirm the quality and function of the goods, without affecting the integrity of the goods; However, the use of goods beyond the needs of inspection and trial, resulting in a substantial depreciation of the value of goods, should be regarded as poor condition of goods. In JD.COM, as long as the original quality and function can be maintained and the goods, accessories and trademarks are intact, unpacked goods can be returned. Within seven days from the date of receipt of the goods (counting from the second day after receipt), the goods are in good condition and can be returned for seven days without reason. It should be noted that if the returned gift is lost, the refund will be deducted from the gift fee. Due to the attribute problems of some commodities, 7 days unreasonable return is not supported.
