Chain of Custody (CoC)

Chain of Custody supports a product content claim. It is a system to document and ensure the path taken by a defined entry material through all stages of transfer and production, to the final product. The Chain of Custody preserves the identity of the raw material. Chain of custody keeps the integrity of a product intact through a system (such as transaction certificates) designed to track the content through the supply chain. A Chain of Custody system can either be controlled through a recognized industry standard or guidelines developed by an initiative.
