Where a combination road vehicle carries a placard load, the documents show which goods are stowed on which unit of the combination. After part of a load is delivered, or goods are pumped out of a tank, bulk container or freight container, the documents are amended where practicable so that they show what types and quantities remain (not required for Class 2 tanks whose quantity is fixed by tank capacity). Goods that appear in the list but are not subject to the Code may be documented under the IMDG, ICAO or IATA code where they are lawfully marked for sea or air, and where they ride in a placarded unit without such documents the paperwork should say the goods are not subject to the ADG Code.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
