Modes and Named Cargo Forms

Markel Insurance’s U.S. overview focuses on ocean cargo and describes shipments by land, air, or sea. For a buyer whose schedule crosses modes, the useful comparison is Aon’s list of cargo forms against Markel Insurance’s stated ocean-cargo scope; ask each team to identify which form and route the proposal will cover. Neither public description determines the issued wording. 3 6
Transit and Storage Stages
Aon describes loading, unloading, storage, and transit, with Excess Storage and Project Cargo among its named options. Markel Insurance’s U.S. overview describes ocean cargo and shipments by land, air, or sea. An importer comparing goods in a warehouse with goods on a vessel can ask Aon which listed form addresses each stage and ask Markel Insurance how its ocean-cargo proposal handles connecting movement and storage. The written form and schedule determine the actual covered locations. 3 6
