What additional risk do shippers often insure against when insuring ocean cargo?

Shippers frequently choose to insure their ocean cargo against war risks in addition to commercial risks due to the unique threats associated with maritime transportation. The ocean environment can expose shipments to a variety of dangers beyond typical commercial risks, such as loss, theft, or damage during transit. War risks refer to situations arising from armed conflict, terrorism, or civil disturbances that could lead to loss of cargo.

By opting for insurance that covers war risks alongside commercial risks, shippers ensure that they are protected against events that could significantly disrupt trade and impact the safety of their goods. This type of insurance is particularly pertinent in regions where political instability or military conflict is prevalent, as these conditions can lead to substantial financial losses if cargo is damaged or lost.

While the other options focus on either natural disasters or specific types of risks like piracy or war without additional coverage, the comprehensive protection of both commercial and war risks reflects a prudent approach to managing the complexities and varied threats in ocean shipping.
