The second level considers tagging location. There are two locations where tags are attached to materials.
Each material type attaches tags to materials ideally at the factory, while on-site tagging continues to happen on current sites.
All the material types without tagging from the factory also have the on-site tagging process. For a specific need, MTM may have an additional tagging process for maintenance (T3).
VTM can include additional on-site tracking. As for KTM, on-site customised pallets instead of delivered pallets can be used.
