What is an example of a major Non-IMDG defect?

A cracked weld at a structural joint is a significant non-IMDG defect because it directly compromises the structural integrity of an intermodal container. Structural joints are critical points where different parts of the container come together, and any failure in these connections can lead to severe safety hazards such as the potential for the container to fail during transportation.

In contrast, minor dents, loose fasteners, and hairline fractures, while they may indicate defects, do not pose the same level of risk to the overall safety and functionality of the container. These less severe issues might be repairable without affecting the basic structural capabilities of the container, thereby not qualifying as major defects under the criteria for safe shipping and handling. Therefore, the cracked weld stands out as a clear example of a major defect that warrants immediate attention to ensure the safety and compliance of intermodal transport.
