Which type of plastic commodity does not require an increase in commodity classification when stored on plastic pallets?

Group A plastic is considered to have a higher fire hazard potential due to its characteristics, including a low ignition temperature and the ability to sustain combustion easily. When it is stored on plastic pallets, it is especially important to recognize this increased risk, which can necessitate an increase in commodity classification to ensure proper fire safety measures are in place.

Conversely, Group B plastics are less hazardous compared to Group A, but still present some risk. Group C and Group D plastics represent even lower risks compared to Group A and B. When these lesser hazard groups are stored on plastic pallets, their classification does not need to be elevated because they do not pose the same level of fire risk as Group A plastics do. This is why identifying Group A as requiring a change in classification is crucial for fire safety, while Group B does not incur such requirements when stored on plastic pallets, maintaining its categorization without the need for escalation in hazard classification.
