Marine cargo insurance is the class of marine cover indemnifying the party with insurable interest in goods - typically buyer, seller or financier - against physical loss of or damage to those goods during international or domestic transit by sea and any connected transit by other modes, written on the Institute Cargo Clauses.
Category: Marine insurance Also known as: marine cargo cover, ocean cargo insurance First codified: Lloyd’s SG Form (17th–19th century); Institute Cargo Clauses 1912 (revised 1963, 1982, 2009) Related legislation: Marine Insurance Act 1906 [1]; Carriage of Goods by Sea Act 1992 [2]; Insurance Act 2015 [3]
Marine cargo insurance is one of the four traditional branches of marine insurance and the historical heart of the Lloyd’s market. The cover indemnifies an assured holding insurable interest in goods against physical loss of or damage to those goods during a defined transit. The standard market wordings are the Institute Cargo Clauses (ICC) maintained by the Joint Cargo Committee, of which there are three principal versions: ICC (A), ICC (B) and ICC (C) [4][5].
Although called marine cargo, modern ICC wordings respond to multimodal transit. The transit clause (cl.8 in the current ICC) begins cover when the goods are first moved within the warehouse at the place named for commencement of transit, continues during the ordinary course of transit including any connected road, rail or air carriage, and terminates on delivery to the final warehouse at destination, on delivery to any other warehouse used by the assured for storage outside the ordinary course of transit, or on expiry of a stated period (60 days for sea transit after discharge from the overseas vessel) [4][5].
Cargo cover differs from carriers’ liability insurance, which protects the carrier against its limited liability under the contract of carriage. It differs from UK goods in transit policies issued to hauliers, which combine limited goods cover with carriers’ liability. And it differs from property insurance covering stock at fixed locations, although stock throughput policies blend cargo and property principles into a single global wording [4][6].
The Marine Insurance Act 1906 is the foundational statute. Key sections relevant to cargo include s.5 (insurable interest), s.16 (insurable value), s.17 (utmost good faith, modified by the Insurance Act 2015), s.18–20 (disclosure, modified by the Insurance Act 2015), s.55 (perils insured and excluded), s.64–66 (average and general average), s.78 (sue and labour) and s.79 (subrogation) [1].
The Insurance Act 2015 introduced the duty of fair presentation for commercial contracts and the suspensive remedy for breach of warranty. Section 13A imposes the implied term of payment within a reasonable time [3].
Contracts of carriage by sea are governed in English law principally by the Carriage of Goods by Sea Act 1971 (enacting the Hague-Visby Rules) and the Carriage of Goods by Sea Act 1992 (governing transfer of rights of suit under bills of lading). The Hague-Visby Rules cap the carrier’s liability at the greater of 666.67 SDR per package or unit or 2 SDR per kilogramme, well below the value of most commercial goods - hence the practical need for cargo insurance [2].
Average is administered under the York-Antwerp Rules, an international code first agreed in 1890 and most recently revised in 2016. The Rules govern the adjustment of general average - the equitable sharing of losses incurred to save the maritime adventure - between the various interests involved.
International market practice is shaped by the International Union of Marine Insurance (IUMI), which publishes statistics and provides a forum for the global marine market [6].
Cargo cover is arranged in two principal forms. Single-shipment cover is bought for occasional movements and issued as a one-off policy or marine certificate. Annual open cover is bought by regular shippers and provides cover automatically for all shipments falling within agreed limits, with monthly or quarterly declarations and premium calculated against declared values [4][5].
Incoterms 2020 (the International Chamber of Commerce trade terms) determine where risk passes between seller and buyer and therefore who has insurable interest at any point in the transit. Under CIF (Cost, Insurance and Freight) the seller arranges and pays for insurance for the buyer’s benefit on at least ICC (C) (the Incoterms minimum, often increased to ICC (A) by sales contract). Under CIP (Carriage and Insurance Paid To) the Incoterms 2020 default was raised to ICC (A) cover. Under FOB (Free On Board) the buyer arranges its own cover from the time risk passes at the ship’s rail. Under DDP (Delivered Duty Paid) the seller retains risk and typically insures for the full transit [4][5].
Claims handling involves notification to the insurer’s nearest correspondent, appointment of a surveyor at destination, gathering of documents (commercial invoice, packing list, bill of lading or air waybill, survey report, claim against carrier) and preparation of an adjustment. Average adjusters are appointed for general average and complex claims. The insurer is subrogated to the assured’s rights against the carrier under s.79 of the Act and pursues recovery subject to convention limits and time bars (one year under Hague-Visby) [1][2].
A marine certificate is the document issued under an open cover for a specific shipment, evidencing cover and presentable under a letter of credit. The certificate sets out the assured, the conveyance, the goods, the insured value, the conditions and the claims agent at destination.
Coverage variations reflect the commodity, the route, the value at risk and the trade custom. ICC (A) provides ‘all risks’ cover, the default for most general cargo and a CIP minimum under Incoterms 2020. ICC (B) provides intermediate cover on named perils. ICC (C) provides the narrowest cover, often used for bulk commodities and low-value goods and the CIF minimum [4][5].
Institute War Clauses Cargo and Institute Strikes Clauses Cargo cover the war and strikes risks excluded from the main clauses. The Joint Cargo Committee maintains additional clauses for specific commodities including frozen foods, frozen meat, oil and bulk oil, coal, jute and natural rubber.
Specialist sub-classes include project cargo (large, often abnormal-load shipments for energy and infrastructure projects), fine arts (museum loans, gallery exhibitions and high-value art transit), specie (bullion, coins and high-value cash in transit), livestock and refrigerated cargo. Stock throughput policies combine cargo and property cover for global manufacturers and traders.
A UK exporter sells a consignment of machined components to a buyer in South Korea for £450,000 on CIP Busan terms. The exporter declares the shipment under its annual open cover with ICC (A) including War and Strikes clauses, for an insured value of £495,000 (CIP value plus customary 10% notional profit). The goods are shipped in a 40-foot container loaded at a UK port and discharged at Busan. During the passage the vessel encounters severe weather and rolls heavily; several containers in the stack above are damaged and the exporter’s container is contaminated by spillage from a fractured container above. The buyer notifies the insurer’s local correspondent, an independent surveyor inspects the container at the destination terminal, and the cargo is assessed as 60% damaged. The insurer pays the indemnified loss to the buyer (as named assured under the marine certificate), takes subrogated rights against the carrier under the Carriage of Goods by Sea Act 1992 and pursues recovery subject to Hague-Visby package limits.
