[3](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance") [7](https://www.cna.com/sites/default/files/assets/d76bf361-a08f-45e2-a2c1-151732208c58/2402-MKTG-ss-Ocean-Cargo-Marine-v5.pdf?ContentCache=NONE&MOD=AJPERES "Ocean Cargo | CNA")

## 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. [8](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [9](https://www.trade.gov/shipping-options "Shipping Options") [10](https://www.trade.gov/special-documents "Special Documents") [11](https://www.nationalunity.com/National/MotorTruckCargoLiability.pdf "Motor Truck Cargo Legal Liability Coverage")

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

### Transit Route and Optional Extensions

CNA describes insured goods moving from inland origin through final inland destination, including water or air transit and connecting conveyance. Its sell sheet also lists domestic and foreign transit, incidental storage, exhibition, and consignment options. Aon names loading, unloading, storage, and transit in its cargo description and offers separate excess-storage and stock-throughput options. Buyers should map route segments and storage intervals to determine whether one continuous form or added options are needed. [7](https://www.cna.com/sites/default/files/assets/d76bf361-a08f-45e2-a2c1-151732208c58/2402-MKTG-ss-Ocean-Cargo-Marine-v5.pdf?ContentCache=NONE&MOD=AJPERES "Ocean Cargo | CNA") [3](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance")

### Policy Administration and Claims

CNA’s CNACargo.com lets agents and policyholders manage policies, issue certificates, and locate claims-settling agents; CNA also names dedicated cargo claims specialists. Aon describes cargo claims management and a global network coordinating local expertise. For an operations team shipping frequently, the distinction is a named policy administration portal versus broker-coordinated service. Confirm portal access, certificate turnaround, and the entity that makes claim decisions. [7](https://www.cna.com/sites/default/files/assets/d76bf361-a08f-45e2-a2c1-151732208c58/2402-MKTG-ss-Ocean-Cargo-Marine-v5.pdf?ContentCache=NONE&MOD=AJPERES "Ocean Cargo | CNA") [3](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance")

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

- Are incidental storage, exhibition, and consignment locations included or separately endorsed? [3](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance") [7](https://www.cna.com/sites/default/files/assets/d76bf361-a08f-45e2-a2c1-151732208c58/2402-MKTG-ss-Ocean-Cargo-Marine-v5.pdf?ContentCache=NONE&MOD=AJPERES "Ocean Cargo | CNA")
- Who issues certificates and decides claims, and what portal access is available to the policyholder? [3](https://www.aon.com/en/capabilities/risk-transfer/cargo-insurance "Cargo Insurance") [7](https://www.cna.com/sites/default/files/assets/d76bf361-a08f-45e2-a2c1-151732208c58/2402-MKTG-ss-Ocean-Cargo-Marine-v5.pdf?ContentCache=NONE&MOD=AJPERES "Ocean Cargo | CNA")
