Marine Cargo Insurance for Bulk Commodity Shipments
Quote from chief_editor on June 10, 2026, 5:30 pmHow Institute Cargo Clauses A, B, and C differ, what is excluded from standard marine cargo coverage, and why CIF minimum insurance often does not protect commodity buyers.
Marine cargo insurance is a contract under which an insurer agrees to indemnify a cargo owner for physical loss or damage to goods during transit by sea, air, or land. In commodity trade, where a single bulk shipment can represent tens of millions of dollars in value and transit may last 30 to 60 days, cargo insurance is the standard financial protection against the physical risks of transportation—vessel accidents, fire, theft, contamination from sea water entry, and weather damage.
Understanding what a marine cargo policy actually covers—and what it explicitly excludes—is essential for commodity buyers because the standard insurance terms required by Incoterms CIF contracts provide significantly narrower coverage than buyers often expect.
Institute Cargo Clauses: A, B, and C
The London market standard for cargo insurance is defined by the Institute Cargo Clauses (ICC), published by the Lloyd's Market Association and the International Underwriting Association. Three versions exist, and the differences determine coverage substantially.
ICC (A) is an all-risks policy that covers physical loss or damage to cargo from any cause, except those specifically excluded in the clauses. It provides the broadest coverage of the three versions and is the standard for high-value or sensitive cargoes, including most agricultural commodities, refined petroleum products, and metals with quality sensitivity.
ICC (B) is a named-perils policy that covers fire or explosion, stranding, grounding, sinking or capsizing, overturning or derailment of land transport, collision, discharge at a port of distress, earthquake or lightning, washing overboard, entry of sea or lake water into the vessel or container, and total loss of a package during loading or unloading. It does not cover theft, deliberate damage, or contamination unless caused by a listed peril.
ICC (C) is the most restricted form, covering only the major casualties: fire or explosion, vessel stranding, grounding, sinking or capsizing, overturning or derailment of land transport, collision, and discharge at a port of distress. It does not cover washing overboard, water entry, earthquake, or package loss during loading. Under Incoterms 2020, a seller under CIF terms must provide only ICC (C) coverage as the minimum. Buyers who assume CIF means broad protection receive a narrow policy.
The practical consequence for commodity buyers: if goods are damaged during a CIF voyage because of condensation, heavy weather wetting through hatch seals, or theft at a transhipment port, the ICC (C) policy will not respond unless the damage can be attributed to one of the listed major casualties. Buyers who need broader coverage—ICC (A) or ICC (B)—must negotiate this requirement into the CIF contract or arrange their own coverage.
Key Exclusions Across All ICC Forms
Inherent vice is excluded across all three ICC versions. Inherent vice means natural deterioration or damage arising from the nature of the goods themselves—grain that ferments because it was too wet at loading, rubber that oxidizes during transit, or fruit that ripens and spoils. If the cargo was already degraded before loading, or deteriorated solely from its own properties, the insurer has no liability.
Delay is not covered by standard cargo insurance. Financial losses arising from delayed delivery—missed market windows, storage costs at the buyer's end, or penalties in an onward sale contract—are excluded. This matters significantly in commodity trade, where late arrival can affect basis prices or delivery obligations. Delay coverage requires a specific endorsement and is not standard in commodity markets.
Inadequate packing is a common exclusion that affects equipment importers. Damage to industrial goods caused by inadequate packing, insufficient corrosion protection, or improper preparation for transit is excluded. A heat exchanger that arrives corroded because protective coatings were not applied before crating is unlikely to generate a successful cargo insurance claim.
War and strikes risk is covered under separate endorsements—the Institute War Clauses and the Institute Strikes Clauses—that are typically arranged alongside the main ICC policy but must be explicitly requested. In trade routes where geopolitical or labor disruption risk is elevated, confirming that war and strikes coverage is in place is not optional.
The sum insured should be set at 110 percent of the CIF value as standard market practice—the additional 10 percent covering the buyer's anticipated profit margin on the transaction, which is also at risk if the cargo is lost. Insuring for cargo value only leaves a routine component of the transaction without coverage.
