Which type of policy would a company use to cover all its shipments over a year?

The correct choice is an annual transit policy. This type of insurance is specifically designed to cover multiple shipments or losses occurring over a specified period, typically one year. Companies that regularly ship goods can significantly benefit from an annual transit policy because it provides comprehensive coverage for all shipments made during that period, streamlining the insurance process and often resulting in cost savings compared to insuring each shipment individually.

This policy type is advantageous for businesses with high shipping volumes or those that transport goods frequently, as it eliminates the need to purchase separate insurance for every single shipment. This not only eases the administrative burden but also provides consistent coverage throughout the year.
