If the payment date of foreign exchange settlement exceeds 90 days from the date of signature on the customs declaration, it needs to be extended, and the time for applying for extension is between 90~ 120 days.

Delayed payment of foreign exchange needs to be registered in the application service platform of the State Administration of Foreign Exchange. After registration with the local foreign exchange bureau, the administrator's account password is given. After logging in, the operator is established. The operator logs in to the application service platform of the State Administration of Foreign Exchange and makes a declaration under the prepayment.
