Then after you pay the foreign exchange, the new monitoring system will record the payment. If the difference between your payment time and customs clearance time (that is, the time shown on the customs declaration form) is more than 30 days (including 30 days), you need to declare the payment record in the new monitoring system (the operation process should be in the operation manual) without verification.
If the time period is within 30 days ... you don't have to do anything, just keep the customs declaration form.
Again, this is the situation in Shanghai. I suggest you consult the Beijing Administration of Foreign Exchange (but the monitoring platform is called the State Administration of Foreign Exchange ... I think it should be universal).
