## 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 CNA and Marsh McLennan Agency Cargo and Transit Insurance?

### Inventory and transit in one supply chain

Marsh McLennan Agency describes cargo stock-throughput, inland transit, motor-truck cargo, and ocean marine options for goods in storage or transit. CNA Ocean Cargo describes goods moving from inland origin to final destination, including air or water and connecting legs. A business with goods at rest and in motion should ask whether MMA can place one stock-throughput structure and how CNA’s storage options apply between shipments. [7](https://www.marshmma.com/us/solutions/cargo-theft-prevention.html "Cargo Insurance | MMA") [4](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")

### Advisor placement and claims tools

MMA directs organizations to discuss placement with an adviser or specialist; its page does not establish a quote or bind timeline. CNA describes its cargo policy portal and dedicated claims specialists. Ask MMA which insurers and forms are available for your supply chain, and confirm with CNA how certificates, policy updates, and cargo claims are handled across countries. [7](https://www.marshmma.com/us/solutions/cargo-theft-prevention.html "Cargo Insurance | MMA") [4](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")
