Cargo Insurance for UK Steel & Metals Shipments

Why Steel and Metals Demand Specialist Cargo Cover

Steel is heavy, dense and hygroscopic. Coils and plates are vulnerable to rust and surface oxidation from condensation, seawater ingress and contact with contaminated dunnage — losses that are frequently disputed under standard wordings because the damage develops over time rather than from a single identifiable event. Non-ferrous metals such as copper cathodes, aluminium ingots and zinc slabs carry high intrinsic value and are a persistent target for theft and short-delivery fraud at transhipment hubs.

The Institute Cargo Clauses (A), (B) and (C) form the baseline for most London-market cargo placements. For steel and metals, the choice between them is consequential. Institute Cargo Clauses (C) cover only named perils — fire, explosion, stranding, sinking, collision and discharge at a port of distress — and will not respond to rust, sweat damage or theft unless those losses are directly caused by a listed peril. Institute Cargo Clauses (A) cover all risks of physical loss or damage subject to the standard exclusions, and are the minimum appropriate starting point for finished steel products and non-ferrous metals. Even under (A), rust and oxidation caused by inherent vice or inadequate packing are excluded, which is why your broker needs to understand your packaging specification, container type and voyage duration before agreeing the wording.

For scrap metal and semi-processed material, underwriters will often insist on (B) or (C) cover with specific endorsements, reflecting the commodity's susceptibility to contamination and the difficulty of establishing pre-shipment condition. If your trading terms require you to hold cover on an (A) basis — as many CIF and CIP contracts do — that needs to be agreed at the point of placement, not discovered after a claim.

Key Risks and What Your Policy Should Address

Physical damage is the most obvious exposure, but it is rarely the largest financial risk for a steel cargo owner. Delay, short-delivery and contamination losses frequently exceed the cost of straightforward physical damage, and they require specific policy language to be recoverable. Your policy should be reviewed against the following risk categories before it is bound.

Rust and oxidation: Seawater wetting and condensation ('ship's sweat' and 'cargo sweat') are the most common causes of claim on steel shipments. Cover for these losses is available but requires an explicit endorsement — it will not be implied by an (A) wording alone. Your broker should be asking the underwriter to confirm whether rust resulting from seawater ingress during the voyage is covered, and whether a surveyor's report on pre-shipment condition is required to support a claim.

Theft and short-delivery: Non-ferrous metals are routinely targeted at ports and during road haulage legs. Your policy should extend to cover theft during the entire transit, including inland legs, storage at intermediate warehouses and transhipment. The warehouse-to-warehouse extension under the Institute Cargo Clauses is the standard mechanism, but its duration is limited — typically 60 days at destination — and that limit can be exhausted if your consignee's yard is congested or customs clearance is delayed.

General average and salvage: If the carrying vessel is involved in a casualty and the master declares general average under the York-Antwerp Rules, your cargo will be arrested at the port of refuge until you provide a general average bond and, usually, a cash deposit or guarantee. Without cargo insurance in place, that deposit comes from your own funds. Your policy should confirm that general average contributions and salvage charges are covered, and your broker should hold a copy of your bill of lading to confirm which version of the York-Antwerp Rules applies — the 1994 or 2016 rules produce materially different contribution calculations.

• Physical loss or damage from all risks (ICC A) or named perils (ICC B/C)
• Rust, oxidation and sweat damage — requires explicit endorsement
• Theft, pilferage and short-delivery, including inland transit
• General average contributions and salvage charges
• Sue-and-labour costs (reasonable expenses to avert or minimise a covered loss)
• Contamination by co-loaded cargo or dunnage
• War and strikes cover (separate Institute War Clauses and Strikes Clauses)

War, Sanctions and High-Risk Trade Lanes

Steel and metals move on some of the world's most exposed trade lanes. Shipments transiting the Black Sea, the Red Sea and Bab-el-Mandeb, the Strait of Hormuz, and ports in Ukraine and Russia face war risk exposures that are excluded from standard Institute Cargo Clauses and must be covered separately under Institute War Clauses (Cargo). War cover is placed in a separate market, is subject to seven-day cancellation provisions, and the premium adjusts — sometimes sharply — in response to incidents in the listed areas. If your voyage transits a Joint War Committee listed area, confirm with us before shipment that your war cover is in place and that the vessel is not subject to a breach warranty.

Sanctions compliance is a separate but related concern. If your cargo originates from, is destined for, or transits through a sanctioned jurisdiction, your policy may be void from inception — not merely suspended. UK sanctions administered by OFSI, EU autonomous sanctions and US OFAC secondary sanctions can all apply simultaneously to a single shipment. Your broker needs to know the full chain of ownership, the flag of the carrying vessel, and the identity of all counterparties before cover is bound. This is not a box-ticking exercise; a sanctions breach can render your entire open cover unenforceable.

Carriage Contracts, Terms of Sale and Where Your Cover Starts

Your cargo insurance obligation depends on your Incoterms and your contract of carriage. Under CIF and CIP terms, you are obliged to provide insurance for the buyer's account — and under Incoterms 2020, CIP requires cover at the ICC (A) level. Under FOB and CFR terms, the risk passes to the buyer at the ship's rail or on loading, and the buyer is responsible for placing their own cover from that point. If you are selling on FOB terms but your buyer has not confirmed their insurance arrangements, your cargo is exposed for the sea voyage.

Your contract of carriage — the bill of lading — determines your rights against the carrier in the event of loss. UK shipments are typically governed by the Hague-Visby Rules as incorporated by the Carriage of Goods by Sea Act 1971. The carrier's liability under Hague-Visby is limited by package or weight, and those limits are low relative to the value of steel cargo. Your cargo insurance bridges the gap between what the carrier pays and your actual loss, and your insurer will subrogate against the carrier to recover what it can. If your bill of lading incorporates a jurisdiction clause pointing to a foreign court, your broker should flag this before you sign — it affects how quickly your insurer can pursue recovery and, ultimately, your renewal terms.

For containerised steel, confirm with your freight forwarder whether the cargo is moving under a house bill of lading or a master bill. House bills issued by an NVOCC may not give you direct rights against the ocean carrier, which complicates both claims and subrogation. Your open cover or specific voyage policy should be endorsed to cover shipments under both types of bill.

Placing Cover: What to Bring to Your Broker

London-market underwriters writing steel and metals cargo want to understand the commodity in detail before they quote. A submission that describes the cargo as 'steel products' will attract either a declination or a heavily qualified quote. The more precisely you can describe what you are shipping, how it is packed, and how it moves, the better the terms you will receive.

For an annual open cover — the most efficient structure if you are shipping regularly — underwriters will want to see your previous 12 to 36 months of shipment data, your claims history, and your standard packing and stowage instructions. If you are placing a specific voyage policy for a one-off shipment, the turnaround from submission to binding can be as short as 24 to 48 hours for straightforward voyages, but allow more time if the cargo is high-value, the voyage transits a war-risk area, or the vessel is not on a recognised classification society's register.

Your broker should also confirm whether your open cover includes a held-covered provision for shipments that exceed the declared sum insured or that transit areas not originally declared. Without held-covered language, a shipment that falls outside the declared parameters is uninsured from the moment it departs.

• Full commodity description: grade, form (coil, plate, billet, ingot, scrap), finish and packing
• Voyage details: ports of loading and discharge, transhipment points, inland legs
• Carrying vessel details or, for open cover, your typical vessel profile and age limits
• Terms of sale (Incoterms) and whether you hold the bill of lading
• Declared value basis: invoice value plus agreed percentage for freight and insurance
• Claims history for the past three years
• Any existing open cover wording for review and comparison

Frequently asked questions

Do I need a separate war risk policy for steel shipments through the Red Sea?

Yes. War, strikes and related perils are excluded from the standard Institute Cargo Clauses and must be covered under separate Institute War Clauses (Cargo) and Institute Strikes Clauses (Cargo). The Red Sea and Bab-el-Mandeb are currently listed by the Joint War Committee as high-risk areas, which means additional premium applies and the vessel must not be in breach of any warranty attached to the war cover. Confirm with us before each shipment that your war cover is current and that the carrying vessel is not subject to a breach condition.

What happens if my steel cargo is damaged by condensation during the voyage?

Condensation damage — whether from ship's sweat or cargo sweat — is one of the most frequently disputed claims on steel shipments. Under a standard Institute Cargo Clauses (A) wording, the loss may be excluded as inherent vice or inadequate packing unless you can demonstrate that the condensation resulted from an external cause. The practical solution is to negotiate an explicit rust and oxidation endorsement at the time of placement, supported by a pre-shipment survey confirming the cargo's condition. If you are already in a claim situation without that endorsement, contact us immediately — the strength of your position depends on the survey evidence available.

My buyer is handling insurance under FOB terms — do I still need cover?

Under FOB terms, the risk passes to your buyer once the cargo is loaded on board, and the buyer is contractually responsible for insurance from that point. However, if your buyer fails to place cover, or places inadequate cover, you have no recourse against their insurer and your only remedy is against the buyer directly. If the buyer is in a jurisdiction where enforcement is difficult, or if the cargo value is material to your business, consider placing contingency cargo insurance to protect your interest in the event the buyer's cover fails.

How long does it take to bind a specific voyage policy for a steel shipment?

For a straightforward voyage on a classified vessel between established ports, we can typically bind cover within 24 to 48 hours of receiving a complete submission. If the voyage transits a war-risk area, the vessel is older or on a less common register, or the cargo is high-value non-ferrous metal, allow additional time. Do not ship before cover is confirmed in writing — a verbal indication is not a binding contract.

What is an open cover and is it right for my steel trading business?

An open cover is an annual facility that automatically insures each shipment you declare, up to agreed limits per conveyance and per location. It is the most efficient structure if you are shipping steel or metals regularly, because you do not need to place a new policy for each voyage. You declare each shipment to us as it departs, and the cover attaches automatically. The key discipline is keeping your declarations current — an undeclared shipment is not covered, and a pattern of late declarations can give underwriters grounds to dispute a claim.

Does my cargo insurance cover the inland haulage leg from the port to my customer's yard?

The warehouse-to-warehouse extension in the Institute Cargo Clauses covers inland transit as part of the ordinary progress of the voyage, but the cover terminates 60 days after discharge from the ocean vessel — or earlier if the cargo is delivered to the final warehouse. If your customer's yard is congested, customs clearance is delayed, or the cargo is held in a bonded warehouse beyond that period, you need to confirm with us that the cover has not lapsed. We can arrange an extension or a separate inland transit endorsement where needed.
