Baldwin’s Insurance Advisory Solutions group describes commercial-risk and employee-benefit services for businesses and private-risk management for high-net-worth individuals and families; its business-insurance page outlines a five-step RiskMap process. [1](https://www.sec.gov/Archives/edgar/data/1781755/000178175526000018/bwin-20251231.htm "The Baldwin Insurance Group, Inc. Form 10-K for fiscal year ended December 31, 2025") [2](https://baldwin.com/business-insurance/ "Business Insurance") [The Baldwin Group profile](https://spot.insure/insurance-providers/baldwin) ## What Is Marsh McLennan Agency? Marsh McLennan Agency provides business insurance and employee health and benefits, alongside retirement, wealth, and private-client services across the United States and Canada. Its US small-business page lists six common coverage types and directs buyers to request a personalized quote by phone; the insurer and terms for a specific placement must be confirmed in the proposal. [4](https://www.marshmma.com/us/mma/about-us.html "Who We Are") [5](https://www.marshmma.com/us/solutions/small-business.html "Small Business Insurance Solutions") [Marsh McLennan Agency profile](https://spot.insure/insurance-providers/marsh-mclennan-agency) ## 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 ### Forms and Supply-Chain Stages The Baldwin Group lists cargo insurance among solutions for transportation clients but does not specify a form or covered transit stage. Marsh McLennan Agency (MMA) describes stock-throughput, inland transit, motor-truck cargo and ocean marine options for goods in storage or transit. This gives a buyer several named approaches to compare when inventory moves between warehouse and customer; Baldwin’s public summary leaves the exact structure to its placement discussion. Ask whether one policy follows goods through storage and shipment or whether separate sections and limits apply. [3](https://baldwin.com/business-insurance/industries/transportation/ "Transportation Insurance & Risk Management") [6](https://www.marshmma.com/us/solutions/cargo-theft-prevention.html "Cargo Insurance | MMA") ### Services and Placement Baldwin describes transportation program review and loss mitigation. MMA invites organizations to contact an adviser or specialist and does not establish a bind timeline or universal cargo limit. Neither record identifies the carrier for an individual placement. Provide both teams with the same commodity, annual values, routes and storage locations, then compare insurer, exclusions and per-location limits rather than relying on the catalogue labels.

[3](https://baldwin.com/business-insurance/industries/transportation/ "Transportation Insurance & Risk Management") - Ask MMA which option fits each stage, and identify the insurer, sublimits and policy period.

The reviewed public sources do not establish a representative customer rating for The Baldwin Group’s commercial advisory business. BBB pages show different legal entities: an A+ regional insurance-agency grade with zero listed reviews and complaints for The Baldwin Group Mid-Atlantic, LLC, and an A- grade plus six complaints in three years for The Baldwin Group Personal Insurance, LLC. A 2026 personal-lines complaint describes delayed refund handling. A separate National General auto review mentions a Baldwin referral but concerns insurer policy administration.
