## 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")

## Key Differences in Cargo and Transit Insurance

### What the Coverage Follows

Chubb lists international ocean and air transit, U.S. and Canadian domestic transit, foreign inland transit, domestic and foreign warehousing, and barge or connecting-conveyance movement. MMA describes stock-throughput, inland transit, motor-truck cargo, and ocean marine options for stored or moving goods. A multinational shipper can use these lists to map each leg, but must confirm territories and transfers in the chosen policy rather than treating a product list as worldwide coverage. [4](https://www.chubb.com/us-en/business-insurance/worldwide-ocean-cargo-insurance.html "Worldwide Ocean Cargo Insurance") [7](https://www.marshmma.com/us/solutions/cargo-theft-prevention.html "Cargo Insurance | MMA")

### Program and Buyer Fit

Chubb also names war, strikes, riots, and civil commotion among its cargo coverage options and says it has a global network of nearly 400 risk engineers. MMA’s overview does not enumerate those political-risk extensions or comparable engineering resources. For shipments through higher-risk routes, ask which exclusions can be bought back, how security advice is delivered, and whether those services apply to the proposed carrier and territory. [4](https://www.chubb.com/us-en/business-insurance/worldwide-ocean-cargo-insurance.html "Worldwide Ocean Cargo Insurance") [7](https://www.marshmma.com/us/solutions/cargo-theft-prevention.html "Cargo Insurance | MMA")

## What to Confirm in Cargo and Transit Insurance Quotes

- Ask Chubb which listed political-risk protections are included, their limits, and the countries or conveyances excluded.
- Ask MMA which territories, warehousing stages, and war or strike extensions are included in the selected form.
- Ask each provider to identify the carrier, reporting process, and shipment stages insured by the proposed form. [4](https://www.chubb.com/us-en/business-insurance/worldwide-ocean-cargo-insurance.html "Worldwide Ocean Cargo Insurance") [7](https://www.marshmma.com/us/solutions/cargo-theft-prevention.html "Cargo Insurance | MMA")
