What Are the Key Differences Between Aon and WTW Cargo and Transit Insurance?

Facility and Form Menu

Aon’s overview names General Cargo, Excess Storage, Stock Throughput, and Project Cargo/Marine Delay in Start-Up. WTW’s U.S. WOLF Cargo Panel brochure describes Marine Cargo, Inland Transit, and Stock Throughput placements through a facility with participating markets. The facility is a distinct route for a buyer to ask about, while Aon’s page describes its broader cargo menu; neither list identifies the insurer selected for a specific account. Compare the proposed wording and carrier participation for the actual schedule rather than treating either list as a policy. [2] [10] [9]

Binding Terms and Document Review

WTW’s 2025 North American Corporate Risk & Broking terms say an insurer quote is not confirmation of coverage; for placements governed by that edition, WTW seeks a formal insurer commitment, typically a binder, when the client orders binding. Those terms also describe reviewing binders, policies, and endorsements against negotiated terms. Aon describes cargo broking and claims management. For a scheduled start date, ask what binding confirmation and document review will apply to the specific WTW engagement and who will confirm the insurer’s effective time. [7] [2]

What Should You Confirm in Aon and WTW Cargo and Transit Insurance Quotes?

  • Is the WOLF panel available for this cargo schedule, and which participating insurer would quote it? What Aon forms would cover the same goods? [10] [2]
  • If this engagement is governed by WTW’s 2025 North American terms, who confirms binding and effective time, and who compares the issued policy with negotiated terms? [7] [2]

Aon lists General Cargo, Excess Storage, Stock Throughput, and Project Cargo/Marine Delay in Start-Up. WTW documents Marine Cargo, Inland Transit, and Stock Throughput through its U.S. WOLF Cargo Panel.
