What does a "racked" container refer to?

A "racked" container refers to a container that has undergone twisting, which affects its structural alignment. This condition typically occurs due to excessive stress or force applied during transportation or handling, leading to a misalignment of its corners. When a container is racked, it may not sit properly on a vehicle or when stacked, which can pose safety risks and compromise the integrity of the cargo inside. Understanding this definition is crucial for inspection certifiers, as it helps identify potential issues that could lead to further damage or hazards during transport.

The other options describe different types of damage or conditions that do not align with the specific twisting and misalignment characteristic of a racked container. Corrosion, visible dents, and overloading imply distinct mechanical failures or wear and tear that do not address the unique structural issues associated with a racked container.
