## Research Scope and Use

Use this comparison to evaluate AIG and Aon for Cargo and Transit Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

AIG describes cargo for land, sea, and international transit and lists route and packaging consultations. Aon lists general cargo, excess storage, stock throughput, and project cargo options, with brokered placement. [3](https://www.aig.com/home/risk-solutions/business/specialty-risks/marine/ocean-cargo "Ocean Cargo Insurance") [6](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance")

## What Is AIG?

AIG is the marketing name for American International Group, Inc.; AIG says its insurance products are written or provided by subsidiaries or affiliates. Its U.S. business pages list commercial casualty, property, cyber, management and professional liability, and specialty programs, but a brand-level page does not identify the insurer for a particular policy. [1](https://www.aig.com/investor-relations "Investor Relations") [2](https://www.aig.com/home/risk-solutions/business "Business")

[AIG profile](https://spot.insure/insurance-providers/aig)

## 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. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account. [4](https://www.aon.com/en/about/leadership-and-governance/brokerage-terms-of-service-for-commercial-risk-solutions-us "Commercial Risk Solutions U.S. Brokerage Terms of Service") [5](https://www.aon.com/en/capabilities/middle-market-clients "Middle Market Clients")

## 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. [7](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [8](https://www.trade.gov/shipping-options "Shipping Options") [9](https://www.trade.gov/special-documents "Special Documents") [10](https://www.nationalunity.com/National/MotorTruckCargoLiability.pdf "Motor Truck Cargo Legal Liability Coverage")

## Key Differences in Cargo and Transit Insurance

### Shipment Types and Coverage Structures

AIG lists importers, exporters, manufacturers, wholesalers, and distributors, with general, bulk, and project cargo moving across land or sea. Aon describes cover for raw materials, components, finished goods, and appliances moving by road, rail, sea, or air, and names excess storage and project cargo among its options. If a shipment includes storage between legs, ask Aon whether excess storage is needed and AIG how its proposed structure addresses the same interval. [3](https://www.aig.com/home/risk-solutions/business/specialty-risks/marine/ocean-cargo "Ocean Cargo Insurance") [6](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance")

### Risk and Claims Support

AIG lists route, conveyance, packaging, and security consultations and marine loss-control engineering. Aon describes cargo risk consulting, claims management, and a global network coordinating local expertise. Both are broker or insurer support descriptions, not guarantees of claim recovery; compare the actual service contact and claims process for the carrier named on each quote. [3](https://www.aig.com/home/risk-solutions/business/specialty-risks/marine/ocean-cargo "Ocean Cargo Insurance") [6](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance")

## What to Confirm in Cargo and Transit Insurance Quotes

- Ask Aon to specify whether its quote includes excess storage or stock throughput; ask AIG to name the structure covering warehouse pauses. [3](https://www.aig.com/home/risk-solutions/business/specialty-risks/marine/ocean-cargo "Ocean Cargo Insurance") [6](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance")
- Request the insurer and policy wording from both providers; Aon identifies itself as the cargo broker. [3](https://www.aig.com/home/risk-solutions/business/specialty-risks/marine/ocean-cargo "Ocean Cargo Insurance") [6](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance")
- Ask what route-security work and claims assistance will be available on your shipment. [3](https://www.aig.com/home/risk-solutions/business/specialty-risks/marine/ocean-cargo "Ocean Cargo Insurance") [6](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance")

## Offering Details

| Criteria | AIG Ocean Cargo Insurance | Aon Cargo and Transit brokerage and risk-advisory offering |
| --- | --- | --- |
| Role in This Line | AIG markets Ocean Cargo insurance and related global/captive solutions. The page does not name the issuing subsidiary for a particular buyer’s policy. [3](https://www.aig.com/home/risk-solutions/business/specialty-risks/marine/ocean-cargo "Ocean Cargo Insurance") (Evidence: Company-reported; scope: Role in this product is limited to the description on the linked AIG source..) | 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. [6](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..) |
| Issuing Insurer | Confirm in your quote. | 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. [6](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. This does not establish that no insurer or producing entity is available..) |
| Who It’s For | AIG names importers, exporters, manufacturers, wholesalers, and distributors with international transit exposures, including containerized general cargo, bulk/break-bulk and project cargo. [3](https://www.aig.com/home/risk-solutions/business/specialty-risks/marine/ocean-cargo "Ocean Cargo Insurance") (Evidence: Company-reported; scope: Audience is the segment AIG names on the linked source; this is not an underwriting decision, quote or guarantee of availability..) | Aon addresses businesses across industries that move raw materials, components, finished goods and appliances by road, rail, sea or air, domestically and internationally.

| Coverage Features | AIG describes protection for goods moved across land, sea or international borders and lists general cargo, bulk/break-bulk and project cargo. It also lists stock-throughput, captive/fronting and logistics package structures; those examples do not settle any buyer’s policy scope. [3](https://www.aig.com/home/risk-solutions/business/specialty-risks/marine/ocean-cargo "Ocean Cargo Insurance") (Evidence: Company-reported; scope: AIG’s public product description is not the policy. Actual entitlement depends on the applicable issued form, endorsements and declarations..) | 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. [6](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. It does not establish an individual insured’s policy entitlement; the insurer’s form, endorsements and declarations control..) |
| Limits and Retentions | The page advertises $50 million transit capacity and $50 million storage/warehouse capacity, with natural-catastrophe sublimits stated as $10 million per occurrence and annual aggregate. These are advertised capacity figures, not an individual quote or policy limit. [3](https://www.aig.com/home/risk-solutions/business/specialty-risks/marine/ocean-cargo "Ocean Cargo Insurance") (Evidence: Not publicly disclosed; scope: This statement reports only what the linked public source discloses and does not substitute for a quote or issued policy..) | The reviewed page does not state a standard buyer-specific limit, retention or deductible for this placement. Confirm amounts, sublimits and conditions in the quote and issued policy. [6](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance") (Evidence: Not publicly disclosed; scope: Aon’s global product/capability page reviewed 2026-09-30; no buyer quote or policy form was reviewed..) |
| Risk Services | AIG lists route, conveyance, packaging and security consultations, marine loss-control engineering, and claims support. Its Marine Claims Promise is conditional on confirmed coverage and applies to specified expense categories and agreed loss estimates. [3](https://www.aig.com/home/risk-solutions/business/specialty-risks/marine/ocean-cargo "Ocean Cargo Insurance") (Evidence: Company-reported; scope: The linked page describes company-reported support; specific account services and third-party arrangements must be confirmed..) | 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.

## AIG Reviews

Review Score: 4.4 / 10 from 2 rated sources, equally weighted.

Customer ratings for AIG are low: Trustpilot shows 1.9 out of 5 from 252 reviews, and NerdWallet gives 2.5 stars and notes more claims complaints than expected. These pages cover many AIG products and countries, so they only loosely describe business insurance.

- NerdWallet: NerdWallet editorial rating 2.5 (stars). NerdWallet’s editorial business-insurance comparison; the AIG entry concerns commercial liability and property insurance, not a quantified policyholder-review sample. The page’s complaint statement and 2.5-star editorial rating are source-specific and must not be recast as a consumer average. Checked 2026-09-29.

- Trustpilot: Trustpilot TrustScore 1.9 (out of 5); 252 reviews.

## Aon Reviews

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.
