Are you a class A enterprise? If yes, there is no need to extend the registration within 90 days, which means that the remittance within 90 days can be ignored according to the export date. However, payments over 90 days should be registered within 30 days after the export date. If you don't register, the amount will turn red relative to the company's indicators, then SAFE will focus on monitoring your enterprise and will be audited. Oh, if security doesn't bother you, you don't have to worry.
