Marine cargo insurance covers accidental loss or damage while goods are in transit. Who buys it depends on the Incoterms: under FOB or FCA the buyer usually arranges cover, while under CIF or CIP the seller arranges minimum cover even though risk has already transferred. Steel shipments are high-value and pass through many handovers, so cover is normally based on the CIF value plus an agreed percentage. Rates depend on the cover, cargo value, route and insurer, and there is no fixed figure. If cargo arrives damaged, inspect on the spot, record evidence, notify the carrier and insurer in writing, and keep all documents.

This guide explains what cover is, who buys it, how the value is set, and how to claim.

Why insurance matters

A shipment passes through the factory, trucking, the export port, the vessel, the import port, customs and inland delivery. The Incoterms transfer risk between parties, but a risk transfer point does not mean anyone has actually bought insurance.

What is usually covered

Cover depends on the policy wording. Cargo clauses commonly respond to external accidents during transit, such as heavy weather, vessel or transport accidents, fire, loading and discharge damage, and partial loss, subject to the chosen level of cover.

What is usually excluded

Policies commonly exclude ordinary wear and tear, inherent vice or rust that develops without an external cause, inadequate packaging, delay, the receiver’s own fault, and unseaworthiness known to the insured. War and strike risks are often separate add-ons. Always read the policy.

Levels of cover

The Institute Cargo Clauses (A), (B) and (C) are a common reference. (A) is the widest, (B) is narrower, and (C) is the most limited. The exact scope follows the policy, not the label.

LevelBreadthTypical use
ICC (A)Widest coverHigh-value or long-route shipments
ICC (B)Middle coverNamed perils and partial losses
ICC (C)Limited coverMajor casualties only

Who buys under common terms

TermTransportInsurance
EXW / FCA / FOBBuyerBuyer arranges
CIF / CIPSellerSeller arranges minimum cover

Under CIF the seller is normally required to arrange only minimum cover; buyers who want wider cover often add their own.

How the insured value is set

Cover is commonly based on the CIF value plus an agreed percentage, often around 110%, subject to the insurer and the contract. Do not insure only the steel cost; duties and freight may also be exposed.

Duration of cover

Many cargo clauses use a warehouse-to-warehouse principle, from the named departure warehouse to the named destination warehouse, but the exact start and end follow the clause and require a continuing interest in the goods.

If cargo arrives damaged

  1. Inspect at the time of collection and take dated photos
  2. Note exceptions on the delivery or port documents
  3. Notify the carrier and terminal in writing within the required time
  4. Notify the insurer and its local survey agent
  5. Keep the bill of lading, invoice, packing list, policy and discharge records
  6. Do not dispose of damaged goods without agreement
  7. Cooperate with subrogation against the responsible party
