Enterprise direct settlement exchange rate and tax rebate rate are two concepts, that is, not the same thing. The exchange rate is 6.874 if the settlement rate is the amount of RMB that should be obtained by converting USD into RMB.

You may be talking about foreign trade companies according to the contract price of the settlement rate or calculated according to the median price. This is an agreement between the two companies.
