Practical Tips

  1. Sign in advance — Do not wait until you need to declare; complete all types of signing ahead of time
  2. Multi-port signing — If you declare at multiple ports, you need to sign with each corresponding Customs office separately
  3. Regular checks — Renew agreements before they expire
  4. Multi-person authorization — You can grant signing authority to multiple operators
  5. Keep records — Download and save electronic copies of signed agreements

Once electronic signing is completed, your enterprise can enjoy the convenience of paperless customs clearance. Declaration documents submitted online, tax payments processed on the web, inspection notifications received in real time — all of these greatly improve clearance efficiency.
