Delivery vehicles are checked before and during unloading to confirm that the materials stayed safe in transit, for instance seal integrity and freedom from infestation, and temperature records are kept as documented information. Materials are inspected, tested or covered by documents such as a CoA or DoC to confirm conformity before they are accepted or used, with the verification method documented; how often and how deeply to check can follow the hazard the material presents and the assessed risk of the supplier.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
