How can I verify that the bank details are correct (Anti-Fraud)?

Cybersecurity is a priority. HYSF will NEVER change our bank account details via a simple email notification. Our official bank details are printed on the Proforma Invoice (PI) stamped with our company chop. If you receive an email claiming our bank has changed, please call us immediately to verify before transferring funds.

Business Email Compromise (BEC) is a common threat in international trade.

Official Channel: Our bank account is held in the name of “Xiamen Cuida Technology Co., Ltd.”.
Verification: For the first transaction, we recommend transferring a small amount to test the route or conducting a video call with our finance manager to confirm the account numbers visually.
