 The diagram below shows how UNTP-CRM is implemented at the product-level. For example, a mine site produces a shipment of liquified copper, and issues a digital product passport (DPP) that includes various claims about the shipment, such as product origin and sustainability indicators. The mine site also issues a digital traceability event credential that is linked to the shipment DPP and attests to the stage of the supply chain, in this case, raw material extraction and primary processing. This DPP can be digitally linked to digital conformity credentials that are issued by trusted authorities about a shipment or mine site.
