What Is Marine Cargo Insurance?
Marine cargo insurance covers the physical goods and merchandise transported in international trade against loss, theft, and damage during transit by sea, air, and overland. Despite the name "marine," modern marine cargo policies cover the entire transit from the seller warehouse to the buyer warehouse, including inland road legs, sea or air transport, and port handling.
Marine cargo insurance is one of the oldest forms of commercial insurance, with roots in the Lloyd of London market dating back to the 17th century. The standardised policy wordings - the Institute Cargo Clauses - are produced by the Lloyds Market Association and are used globally as the basis for cargo insurance contracts.
KEY FACTS

Institute Cargo Clauses: A, B, and C
ICC A (All Risks): The broadest cover. Covers all risks of loss or damage to the insured cargo except for specifically excluded causes (inherent vice, delay, war, strikes, and similar excluded perils). ICC A is the recommended basis for most cargo.
ICC B (Intermediate): Covers a specified list of named perils including fire, explosion, vessel sinking or stranding, collision, earthquake, lightning, washing overboard, water damage from sea water, total package loss in loading/unloading, and some others. More limited than ICC A.
ICC C (Minimum/Named Perils): The narrowest cover. Covers only the major catastrophe perils: fire, explosion, vessel sinking or stranding, collision, and overturning of land conveyance. Under CIF Incoterms, the seller is only required to arrange minimum ICC C cover - which may leave the buyer significantly underinsured for most cargo types.

Frequently Asked Questions
What is the difference between marine cargo insurance and goods in transit insurance?
GIT insurance covers road transport domestically or on short international overland routes. Marine cargo insurance covers international trade shipments including sea and air freight and the associated overland legs. The two products use different policy wordings - GIT uses UK domestic cargo wordings; marine cargo uses the Institute Cargo Clauses. For international supply chains, marine cargo cover (warehouse to warehouse on ICC A terms) provides the most comprehensive protection.
What are Incoterms and why do they matter for cargo insurance?
Incoterms are standardised international trade terms that define the responsibilities of seller and buyer in a sale contract, including who arranges and pays for freight and insurance. For cargo insurance, the key Incoterms are CIF and CIP (seller arranges minimum cargo insurance) versus FOB, CFR, and EXW (buyer is responsible for arranging insurance). Understanding the Incoterms in a contract is essential to knowing who is responsible for insuring the cargo and what minimum cover level is required.
Does my buyer need their own insurance if I have CIF terms?
Under CIF terms, the seller arranges minimum ICC C cargo cover and provides the insurance certificate to the buyer as part of the shipping documents. CIF minimum cover is very narrow and may not adequately protect the buyer for most cargo types. Many buyers arrange their own additional or replacement cargo cover regardless of the CIF insurance provided by the seller. Buyers should review the ICC C cover provided and consider arranging ICC A cover independently.
What is General Average and does marine cargo insurance cover it?
General Average is a principle of maritime law where costs arising from voluntary sacrifices to save the ship and cargo are shared proportionally among all cargo owners. If a ship captain jettisons some cargo to save the vessel, all cargo owners on that voyage contribute proportionally to compensate the owner of the jettisoned cargo. Marine cargo insurance typically covers the insured cargo owner General Average contribution, protecting them against this potentially significant shared liability.
Can I get marine cargo insurance for a single shipment?
Yes. Single shipment marine cargo insurance is available for one-off or occasional consignments. It is arranged with a Lloyd of London broker or marine cargo specialist and covers the specific consignment from departure to destination. For regular importers and exporters with multiple shipments per year, an open cover policy (which automatically covers all shipments without individual declaration) is more convenient and typically more cost-effective.
