The balance ratio refers to the detailed rules implemented by enterprises according to the Pilot Guidelines for Foreign Exchange Management of Goods Trade: "For businesses that meet one of the following conditions, enterprises should submit the expected date of receipt and payment of foreign exchange or the date of import and export to the local foreign exchange bureau through the monitoring system within 30 days from the actual date of import and export of goods: prepaid goods and prepaid goods for more than 30 days (excluding); The ratio of the total balance at the end of the month specified in "Deferred payment for more than 90 days (excluding)" to the cumulative import, export and trade foreign exchange receipts and payments of the enterprise in the last 12 months.

Total amount difference = enterprise declared import+foreign exchange collection-export-foreign exchange payment, and total amount difference rate = total amount difference/(declared import+foreign exchange collection+export+foreign exchange payment).

Trade credit balance ratio = registered trade credit amount/(customs declaration import and export+foreign exchange receipts and payments amount).
