Adding additional material to an existing certificate
Additional materials that fall under a scope that is already stated on the certificate can normally be added without an additional on-site audit. For products with individually calculated GHG values, the CB must send ISCC an adjusted audit procedure with the GHG value and the GHG value must have been verified.
However, if a material shall be added for a processing unit, an extension audit may be necessary if the new material requires production facilities that have formerly not been part of the audit. The certification body is responsible to determine if an extension audit is required.
