## What Is Aon?

Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America. The public materials reviewed do not identify the licensed producer or insurer for a particular placement.

## What Is WTW?

WTW is an insurance broker whose documented services include manufacturing risk-program design and specialist property and cargo programs. Its marketed property scope includes residential real-estate stakeholders and a separate integrated data-center program; other named capabilities vary in date and geography. [4](https://www.wtwco.com/en-us/industries/manufacturing "Manufacturing") [5](https://www.wtwco.com/en-us/solutions/products/digital-infrastructure-protector "Digital Infrastructure Protector") [6](https://www.wtwco.com/en-us/solutions/marine "Marine") [7](https://www.wtwco.com/en-us/industries/residential "Residential | WTW") [8](https://www.sec.gov/Archives/edgar/data/1140536/000095017025026278/wtw-20241231.htm "WTW 2024 Form 10-K")

## What Is Cargo and Transit Insurance?

Cargo coverage fits a shipper protecting goods it owns or a carrier responsible for another party’s goods. The quote needs to match who bears the loss, the shipment route and storage stops. [11](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [12](https://www.trade.gov/shipping-options "Shipping Options") [13](https://www.trade.gov/special-documents "Special Documents") [14](https://www.nationalunity.com/National/MotorTruckCargoLiability.pdf "Motor Truck Cargo Legal Liability Coverage")

## 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. [3](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance") [10](https://www.wtwco.com/-/media/wtw/solutions/services/wolf-cargo-panel.pdf?modified=20250804132227 "WOLF Cargo Panel") [6](https://www.wtwco.com/en-us/solutions/marine "Marine")

### 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. [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") [3](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance")

## 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](https://www.wtwco.com/-/media/wtw/solutions/services/wolf-cargo-panel.pdf?modified=20250804132227 "WOLF Cargo Panel") [3](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance")
- 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? [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)") [3](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance")

## Aon vs WTW Cargo and Transit Insurance Compared

| Criteria | Aon Cargo and Transit brokerage and risk-advisory offering | WTW Marine Cargo and Inland Transit Brokerage |
| --- | --- | --- |
| Role in This Line | Aon states it offers cargo insurance solutions and describes its role as cargo broker. The page does not name the carrier that would insure a particular shipment or account. [3](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance") (Evidence: Company-reported; scope: Aon’s official global product/capability page. The statement is limited to Aon’s marketing of brokerage or advisory services, not policy issuance..) | Under WTW's North American Corporate Risk & Broking terms, WTW normally acts as the client's insurance intermediary for engagements governed by those terms.

WTW also discloses separate insurer-side services in some arrangements; this does not determine the role in a specific engagement..) |
| Issuing Insurer | The reviewed page does not identify the insurer or the legal producing entity for a specific placement. Ask Aon to identify both for the quoted risk. [3](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance") (Evidence: Not found in reviewed sources; scope: Aon’s global product/capability page reviewed 2026-09-30; no buyer quote, binder or policy was reviewed.

| Coverage Features | Aon describes cargo insurance for physical loss or damage to goods during transportation and describes goods as protected during loading, unloading, storage and transit. Its listed options include General Cargo, Excess Storage, Stock Throughput and Project Cargo/Marine Delay in Start-Up. These are Aon’s product descriptions, not a guarantee that a buyer’s policy includes every category or peril. [3](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance") (Evidence: Company-reported; scope: Aon’s broker-authored explanation of the insurance line.

The brochure's premium threshold is not a policy limit..) |
| Limits and Retentions | The reviewed page does not state a standard buyer-specific limit, retention or deductible for this placement.

| Risk Services | Aon describes cargo broking, risk consulting, claims management and a global network coordinating local expertise. These are brokerage and advisory services, not the insurer’s claim decision or a guarantee of recovery. [3](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance") (Evidence: Company-reported; scope: Company-reported brokerage and advisory services.

## Aon Review Scores for 2026

Review Score: 6.1 / 10 from 3 rated sources, equally weighted.

Public ratings for Aon are low: Trustpilot shows 1.2 out of 5 from 782 reviews, and BBB shows 1.6 from five. Aon is a global firm, so those pages mostly reflect other parts of the business, not large U.S. commercial accounts.

- J.D. Power: Aon study score 822 (out of 1000). Historical 2017 large-commercial-broker study; U.S. and Canada commercial insurance decision-makers at large organizations. J.D.

- Trustpilot: TrustScore 1.2 (out of 5); 782 reviews. Global www.aon.com profile merged with other Aon profiles; mixed experiences include pensions, travel, professional indemnity and Australian business quotation service. The two latter complaints are individual unverified allegations, not evidence of U.S. commercial-placement outcomes or insurer fault.
