Cargo insurance provides coverage for physical loss or damage to goods during transit by land, sea, or air. It is important for shippers to purchase cargo insurance since carrier liability provides limited coverage. There are several types of cargo insurance policies including open cover policies for multiple shipments and specific policies for single voyages. Cargo insurance offers all-risk coverage and covers losses from events like damage during loading/unloading, weather, and theft. Shippers can ensure both goods and shipping costs are covered.
