Cargo in transit is only weakly protected by the carrier, port, or freight forwarder — their liability is limited and doesn't apply to acts of God, accidents outside their control, or many common loss scenarios. Marine cargo insurance (a term that covers sea, air, road, and rail transit despite the name) is how an exporter or importer actually protects the value of a shipment in transit.
The three standard coverage tiers (Institute Cargo Clauses)
ICC Clause A — "All Risks": the broadest standard coverage. Covers loss or damage from any external cause *unless specifically excluded* — rough handling, fire, natural disaster, accidents during loading/unloading. Common exclusions even under Clause A: willful misconduct, delay (even if caused by an insured risk), improper packaging, and "inherent vice" (a product's own natural tendency to spoil or degrade — fresh produce naturally rotting in transit is not a covered loss under any clause). Best for high-value, fragile, or sensitive cargo — electronics, pharmaceuticals, expensive machinery.
ICC Clause B — Named Perils, Intermediate: covers a specific, listed set of risks (fire, explosion, vessel sinking/capsizing, earthquake, discharge at a port of distress) but explicitly excludes things like theft, pilferage, and contamination. Cheaper than Clause A, appropriate for moderately valuable, less sensitive goods.
ICC Clause C — Named Perils, Narrowest: the bare minimum — covers only major catastrophic events (fire, vessel grounding/capsizing/collision). Excludes almost everything else, including water damage and handling damage. This is the coverage commonly treated as the mandatory minimum under CIF-type Incoterms. Appropriate for bulk, low-value, low-risk cargo — not appropriate for anything fragile or high-value.
Important: "all risks" does not mean "every imaginable risk." Even Clause A has real exclusions — always read them, don't assume.
Beyond the three clauses: war and strike coverage
None of ICC A, B, or C cover loss from war, civil unrest, or strikes/riots by default — this needs to be added separately as Institute War Clauses and Institute Strike Clauses. This distinction has caused real, painful claim denials: a shipment insured under "all risk" (Clause A) that gets delayed or damaged by political unrest or a strike will still be denied if war/strike clauses weren't separately added — "all risks" only means all risks *within Clause A's defined scope*, not literally everything. For any shipment headed through a politically unstable route or country, add these clauses explicitly; don't assume Clause A already covers it.
Minimum vs. maximum coverage, in practice
- Minimum coverage = ICC Clause C alone. Satisfies the bare mandatory requirement under Incoterms like CIF, nothing more.
- Maximum coverage = ICC Clause A + Institute War Clauses + Institute Strike Clauses, often with additional negotiated add-ons (theft/pilferage riders, spoilage/contamination coverage for perishables, warehouse-to-warehouse extension for multimodal shipments). Appropriate for high-value cargo, politically unstable routes, or whenever a buyer/bank explicitly demands full protection.
Who has to buy it, and how much
Under Incoterms CIF and CIP, the *seller* is obligated to arrange insurance covering the *buyer's* risk (since risk transfers to the buyer earlier than the seller's cost obligation ends — see ``). Under FOB/FCA/EXW, insurance is the buyer's own responsibility from their risk-transfer point onward. Standard practice, regardless of who's buying it: insure for 110% of the CIF/invoice value, not 100% — the extra 10% covers incidental costs (lost profit margin, re-inspection, etc.) if a claim has to be made.
The documents involved
- Marine insurance policy: the full, detailed insurance contract — either for a single shipment or an open/annual policy covering multiple shipments.
- Marine insurance certificate: proof that a *specific* shipment is covered under an existing open/master policy — this is what typically gets submitted to a bank under an LC, not the full policy document.
- DEC page (declaration page): a plain-language summary of an insurance policy's key terms — vessel, sum insured, coverage type — that's far easier to check for errors than reading a full policy. Always check the DEC page for mistakes (vessel name, insured sum) immediately on receipt; an error here can sink a claim later, and a bank financing the shipment will often ask for this page specifically rather than the full policy.
Where risk actually concentrates in a shipment's journey
Risk isn't evenly spread across a shipment's route — it clusters at specific points: inland transport (accidents, cargo shifting), port/airport loading and handling (mishandling, crane/equipment damage, misplacement), the main international leg (storms, piracy, container loss), destination unloading and customs handling (theft, misrouting, documentation delays), and final inland delivery (theft, local unrest, road conditions). Knowing where a specific shipment's route is weakest helps decide where extra coverage or precautions are actually worth paying for, rather than blanket-insuring everything at the same level.
