What type of insurance protects cargo owners against losses during shipping at sea?

Cargo insurance is specifically designed to provide financial protection for cargo owners against losses or damages that can occur during the transit of goods, particularly during shipping at sea. This type of insurance covers various risks associated with maritime transport, including damage from rough weather, accidents, theft, and other potential perils that could adversely affect the cargo's condition.

While marine insurance does encompass a broader category that includes coverage for ships, cargo, and other liabilities related to maritime activities, cargo insurance focuses solely on the protection of the goods themselves. Therefore, the specificity of cargo insurance in addressing the needs of cargo owners during shipping makes it the correct choice for this context.

Transport insurance and shipping liability insurance may cover certain aspects of shipping and logistics, but they do not directly provide the same level of specialized protection as cargo insurance does for the contents being shipped. Thus, the distinct purpose and scope of cargo insurance solidify its role as the appropriate answer to the question.
