Which of the following is considered special cargo?

Registered mail is considered special cargo due to its unique handling requirements and the added security measures involved in its transportation. Unlike standard freight, which can be handled through regular carrier protocols without special considerations, registered mail demands a greater level of accountability and tracking. This encompasses a strict process that includes detailed record-keeping, secure packaging, and often a more defined chain of custody. Such procedures are vital to ensure the safe delivery of items that may carry significant value, importance, or sensitivity.

In contrast, standard freight consists of regular shipments that do not require extraordinary handling procedures, while document shipments and unclassified materials also fall under more routine transportation without the special security protocols associated with registered mail. Recognizing this distinction is crucial for air freight personnel to ensure compliance with regulations and the appropriate treatment of different types of cargo.
