Certificate Withdrawal: A certificate withdrawal usually relates to a product no longer conforming to the original criteria it was certified against. It may be that the product itself has been withdrawn, or that processes of production or materials have changed significantly, which means that the certificate is no longer valid against the original certification scheme. When this happens, the certificate is removed from our website and is no longer searchable. When withdrawals happen, that means that the certificate is closed, and cannot be re-opened. If the product needs to be re-certified, the process is started as a new project, under a new certificate.
