Shipping insurance is a service that offers financial reimbursement to the sender if a package is lost, stolen, or damaged in transit. Many couriers provide a basic level of insurance, and extra insurance can often be purchased as an add-on. However, many couriers as well as shipping insurers have restrictions on just what types of goods and delivery methods can be insured. For example, UPS will not insure cash, coins, or precious stones. Also, depending on the carrier or insurer, some shipping locations may be excluded from coverage. Similarly, insurance eligibility may be subject to packing requirements.
