To protect your rights and those of Siyutao's artists and craftsmen. We started using a set of certificates of authenticity on 03/21/2026.
Each Certificate of Authenticity features an encrypted password, a unique serial number, and a QR code. It is personally signed by the artist or the craftsman and bears the official seal of the Siyutao art gallery.
Its production uses special paper, ink, and multiple anti-counterfeiting hidden marks. Additionally, the certificate includes a photo of the teapot and its details.
