It provides an overview of what chain of custody, complemented by examples. In one example cited in the document, hazardous materials shippers and receivers must implement chain-of-custody requirements to ensure a positive and secure exchange. It also highlights the potential impacts and risks resulting from a broken chain of custody, and offers an initial framework with five actionable steps for securing chain of custody.
