Which item is NOT required when sending out a category B frozen sample?

In the context of sending out category B frozen samples, the shipper’s declaration is not required. Category B materials are those that are not identified as dangerous goods but still require careful handling and specific labeling during transportation.

The presence of a Class 6.2 sticker indicates that the sample contains infectious substances, requiring appropriate warning and handling precautions. Meanwhile, the Class 9 sticker signifies that the package contains miscellaneous dangerous goods that do not fall under specific classifications but still mandate labeling. Both are critical for compliance with safety regulations.

Additionally, including the weight of dry ice used is essential as it determines how the sample is kept frozen during transportation, impacting its integrity upon arrival.

In summary, while precautions such as the necessary labels and information about dry ice are essential for the safe transit of category B samples, a shipper’s declaration is not a requirement for this category, which clarifies why that option stands out as not necessary in this context.
