What Are the Key Differences Between AIG and Liberty Mutual Inland Marine Insurance?

Property under construction and in motion

AIG markets inland marine for transportation/logistics and construction/equipment exposures. Liberty Mutual describes protection for assets under construction or frequently moved, including construction projects, inventory in transit, jobsite equipment and materials stored by subcontractors. A builder can use those Liberty examples to identify exposures for a quote, while asking AIG whether its construction or transportation product better maps to the same project phases. [1] [4]

Engineering and claims support

AIG describes marine risk consulting, route or equipment-risk reviews and claims resources. Liberty Mutual describes property underwriting, risk-engineering and claims teams working together on complex property risks. Ask whether the proposed inland-marine policy receives those services, particularly for a project with multiple subcontractors, transit legs or temporary storage locations. [1] [4]

Transit and subcontractor custody

Liberty Mutual’s overview frames coverage around assets on the move but does not set cargo, territory or transit conditions for a particular policy; AIG likewise leaves property and causes to the issued terms. Submit project values and locations, then compare coverage during installation, subcontractor custody and transport on both forms. [4] [1]
