Solutions to consumers purchasing substandard commodities

In case commodities or services provided by business operators fail to meet the quality requirements, consumers may return them in accordance with the provisions of the state or as agreed upon by the parties, or require business operators to fulfill their obligations of replacement or repair, among others. In the absence of such provisions of the state or agreements between the parties, consumers may, within seven days of receiving the commodities, return them; and consumers may, if the statutory conditions for rescission of a contract are met after the seven-day period, return them in a timely manner, or, if not met, require business operators to fulfill their obligations of replacement or repair, among others. For the return, replacement, or repair as mentioned above, merchants shall reimburse consumers for freight and other necessary expenses.
