How does a major IMDG defect affect a container's usability for general cargo?

A major IMDG (International Maritime Dangerous Goods) defect typically signifies that the container may not meet safety standards for transporting dangerous goods, which could affect its usability for general cargo. However, the presence of a defect does not automatically render the container completely unusable. In many cases, provided the defect is not severe and does not compromise the structural integrity or safety features of the container, it can still be used for transporting general cargo that is not classified as dangerous.

Containers are often assessed for usability based on the nature of the defect and the type of cargo intended for transport. If the container can safely carry general cargo despite the defect and is deemed fit for that purpose, it can still be utilized. This understanding aligns with why the correct answer asserts that the container may be used for general cargo even in the presence of a major defect under appropriate circumstances and evaluations.

In contrast, while an immediate inspection and repair may be prudent in many situations, it is not universally required for all defects, allowing for some containers to be assigned to transport general cargo if the situation permits. Many defects do not restrict transport strictly to military applications unless specified due to the nature of the defect. Thus, while a defect may limit the types of goods a container can transport,
