Does Inland Marine Cover Materials?
Materials may be covered when the policy describes them as insured property or goods in transit; installation and storage terms matter.
“Materials” could mean stock held for sale, supplies used by a contractor, or a customer’s materials awaiting installation. The California Department of Insurance lists installation floaters, motor truck cargo, and trip transit as distinct forms, while its commercial-property section treats business inventory as business personal property. Those distinctions affect which policy should respond.
Check whether the quote covers materials before installation, during loading and transit, at a jobsite, and after installation. Confirm whether property belongs to you or a customer, whether labor and materials are valued together, and whether temporary storage is allowed. Read the installation completion and project handoff provisions; do not infer that an equipment floater also insures building materials.
