## What Is WTW?

## 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")

## Key Differences in Cargo and Transit Insurance

### What the Coverage Includes

WTW’s U.S. WOLF Cargo Panel describes marine cargo, inland transit, and stock-throughput placements, while MMA lists those categories alongside motor-truck cargo and ocean marine. The two catalogues help narrow the needed form, but neither identifies which carrier will issue a particular buyer’s policy. Request the actual insurer and covered route before comparing terms. [10](https://www.wtwco.com/-/media/wtw/solutions/services/wolf-cargo-panel.pdf?modified=20250804132227 "WOLF Cargo Panel") [3](https://www.marshmma.com/us/solutions/cargo-theft-prevention.html "Cargo Insurance | MMA")

### Access and Service

WTW’s North American terms say an insurer quote alone does not confirm coverage: after a client orders binding, WTW seeks a formal commitment, typically a binder, and reviews policy documents against negotiated terms. MMA invites buyers to discuss placement with an adviser but its offering record does not outline these steps. Ask both teams what confirms bound coverage and who checks the final wording against the quote. [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.marshmma.com/us/solutions/cargo-theft-prevention.html "Cargo Insurance | MMA")

## What to Confirm in Cargo and Transit Insurance Quotes

- Ask WTW which panel market will issue your policy and what document confirms the binder. [9](https://www.wtwco.com/-/media/WTW/notices/BTCD-CRB-NA-June-2025.pdf "Corporate Risk & Broking Brokerage Terms, Conditions & Disclosures (Canada & US)")
- Ask MMA what written confirmation establishes binding and who checks the issued policy against negotiated terms. [3](https://www.marshmma.com/us/solutions/cargo-theft-prevention.html "Cargo Insurance | MMA")
- Ask both providers for the proposed insurer, limits, deductibles, and endorsements before binding. [3](https://www.marshmma.com/us/solutions/cargo-theft-prevention.html "Cargo Insurance | MMA") [10](https://www.wtwco.com/-/media/wtw/solutions/services/wolf-cargo-panel.pdf?modified=20250804132227 "WOLF Cargo Panel")
