Cover for goods while they are in transit, by sea, air, road or rail, and usually for the incidental storage around each leg. There is no single definition of what it covers, because the cover is whatever the policy wording grants. The standard English-law wordings used across the market come in graded forms of differing breadth, from the widest form down to named-perils cover, and the form chosen matters far more than the premium paid. Read the transit cover and the sale term together: who bears risk at each stage, and therefore who has an insurable interest at the moment of loss, follows from the terms of sale rather than from the policy. A buyer insured from a point the seller’s risk has not yet reached is paying for cover it cannot claim on.
Why this entry carries no source list. This is a product category or an official document type rather than a defined term. What it covers or attests is set by the policy wording, the facility terms, or the requirements of the country demanding it — and those differ by insurer, by bank and by jurisdiction. Naming one provider’s brochure as the authority would dress a single firm’s practice as a general rule. Read the wording you are actually being offered.
