To some extent, the difference is "settlement deduction". It means that the amount of foreign exchange paid for import can be deducted from the amount of foreign exchange collected for export, and only the difference can be written off, so the amount of foreign exchange collected and settled by the company is the "difference" between import and export.

Full amount is the write-off management of "all in and all out", and the amount of export proceeds must be collected in full, and the bank settlement will be much larger.

Whether it is "difference" or "full amount", it is only the difference of foreign exchange settlement, and it does not change the import and export amount of enterprises, nor does it change the total foreign exchange receipts and payments of enterprises. It is understood that there is still a system of "differential settlement of foreign exchange" in some areas along the southeast coast.
