Which of the following is an example of a packaging discrepancy?

Container markings incorrect is a clear example of a packaging discrepancy because it directly relates to the labeling and identification of the contents within a package. Proper container markings are essential for identifying the type of material, handling instructions, hazard information, and other critical data that ensure safe and compliant transport and storage of munitions. When the markings are incorrect, it can lead to confusion, improper handling, and safety risks, making it a significant concern in packaging standards.

In contrast, options like weight discrepancy and missing documentation pertain to different aspects of shipment accuracy and compliance rather than the packaging itself. While improper handling involves the physical treatment of packages, it does not refer to packaging discrepancies directly. Each of these factors is crucial, but incorrect container markings specifically highlight issues that arise solely from packaging mistakes.
