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

Industry coverage categories and combined equipment policy

AIG’s inland-marine overview names contractors, transportation/logistics and movable business property. Harper places inland marine within a combined Equipment Insurance product alongside owned-equipment property coverage and equipment breakdown. Its page focuses on equipment that moves to a jobsite or client location. A contractor should compare whether it wants a broader marine placement or Harper’s combined equipment arrangement, then check how each treats property at its premises and away from it. [1] [3]

Owned and non-owned tools

Harper specifically says its product can cover owned equipment in transit or on a jobsite and can include rented or borrowed equipment for which the business is responsible. AIG describes movable property but does not define whether rented gear, transit or jobsite storage is covered in a buyer’s policy. Put owned and non-owned equipment on the submission schedule and confirm valuation and covered causes. [3] [1]

The equipment schedule and quote

Harper asks buyers to send an equipment list through its online quote form, then prices it across willing insurers. AIG’s page describes risk-engineering and claims resources but does not identify the issuing insurer or application route for a specific buyer. Ask Harper which carrier will issue the policy and AIG who will insure the placement; compare deductibles, limits and equipment breakdown treatment. [3] [1]
