ISO 28004-4:2014 provides additional guidance for organizations adopting ISO 28000 that also wish to incorporate the Best Practices identified in ISO 28001 as a management objective on their international supply chains. The Best Practices in ISO 28001 both help organizations establish and document levels of security within an international supply chain and facilitate validation in national Authorized Economic Operator (AEO) programmes that are designed in accordance with the World Customs Organization (WCO) Framework of Standards. ISO 28004-4:2014 is not designed as a standalone document. The main body of ISO 28004-1 provides significant guidance pertaining to required inputs, processes, outputs and other elements required by ISO 28000. ISO 28004-4:2014 provides additional specific guidance on implementing ISO 28000 if compliance with ISO 28001 is a management objective.
