A container can leave Felixstowe in good order, be damaged in heavy weather, delayed at a foreign port, or arrive to find that its buyer has failed. International trade insurance exists because an export sale does not end when the goods leave the works. It continues through a chain of carriers, documents, banks, agents, warehouses and contractual obligations, each capable of producing an expensive dispute.
For many firms, insurance is bought hurriedly when the first overseas order is won. That is understandable, but it is not a sound basis for protection. The key question is not simply whether a policy exists. It is whether the policy matches the goods, the route, the agreed delivery term, the customer and the financial risk being taken.
