This kind of transaction is unacceptable. If the goods are delivered in China, the buyer must be required to pay RMB, and the price must be calculated according to the domestic sales price, because the goods are not exported and cannot enjoy the preferential tax refund.
If dollars must be paid from abroad, the goods must be exported. Because if the goods are not exported and there is no foreign exchange verification form, foreign exchange funds cannot be recorded and must be returned.
