The CodeMark Certification Scheme (CodeMark) is a voluntary third-party building product certification scheme, administered by the Australian Building Codes Board (ABCB). 

It supports the use of new or innovative building products in specified circumstances in Australia, by providing a nationally accepted process for demonstrating compliance with the National Construction Code (NCC).

A Certificate of Conformity is one of several options available for meeting the ‘evidence of suitability’ requirements of the NCC.

The obligations on building control authorities to accept a Certificate of Conformity is determined by the relevant State or Territory legislation, policy or directive. You should check with your building control authority to determine if a Certificate of Conformity is an appropriate form of evidence of suitability for the specific product and your project.
