What is a pinhole defect in a container?

A pinhole defect in a container refers to a small puncture that is often difficult to detect, which can compromise the integrity of the container without creating a large visible hole. This type of defect might not be immediately noticeable, making it particularly concerning for cargo security and safety. Pinhole defects can allow moisture or contaminants to enter, potentially damaging the cargo inside.

The subtlety of a pinhole defect contrasts with options describing more significant defects, such as major perforations or severe dents, which are easily detectable and typically have obvious implications for cargo security and structural integrity. Distinguishing between these types of defects is crucial for proper inspection and maintenance of intermodal dry cargo containers.
