ISO 28003:2007

ISO 28003:2007 contains principles and requirements for bodies providing the audit and certification of supply chain security management systems according to management system specifications and standards such as ISO 28000.
It defines the minimum requirements of a certification body and its associated auditors, recognizing the unique need for confidentiality when auditing and certifying/registering a client organization.
Requirements for supply chain security management systems can originate from a number of sources, and ISO 28003:2007 has been developed to assist in the certification of supply chain security management systems that fulfil the requirements of ISO 28000, Specification for security management systems for the supply chain, and other supply chain security management system International Standards. The contents of ISO 28003:2007 may also be used to support certification of supply chain security management systems that are based on other specified supply chain security management system requirements.
