Key Differences in Cargo and Transit Insurance
Cargo Program Components
AIG lists general, bulk, and project cargo, plus stock-throughput and logistics structures. Marsh McLennan Agency (MMA) names cargo stock-throughput, inland transit, motor-truck cargo, and ocean marine options. A business moving inventory from a plant to a customer may need more than one of these components; ask MMA which placement covers each segment and AIG which structure addresses storage between trips. 3 6
Route Advice and Placement Contact
AIG offers route, conveyance, packaging, and security consultations. MMA invites buyers to discuss placement with an adviser or specialist, and its page does not state an online bind process. Ask who will collect the shipment schedule, which insurer will issue coverage, and what risk advice is available after placement. 3 6
What to Confirm in Cargo and Transit Insurance Quotes
- Ask MMA whether stock-throughput, inland transit, truck cargo, and ocean marine are separate forms or coordinated parts of one program. 3 6
- Ask AIG how its proposed form handles storage, loading, and connecting transport. 3 6
- Confirm the adviser, insurer, claims contact, and service scope for each segment. 3 6
