Malaysia has a long history as a metals producer and exporter, from its heritage as the world's largest tin producer to its current position as an exporter of iron and steel products, aluminium, and strategic minerals including rare earth elements. Malaysia's tin exports reached USD 608.76 million in 2024 (UN COMTRADE, 2024). Iron and steel products are a growing export category, with shipments to markets including Hong Kong, Singapore, Indonesia, Japan, and South Korea. Singapore complements Malaysia as a major metals trading and physical storage hub, hosting LME-registered warehouses and accounting for the vast majority of registered LME inventory for zinc and lead in Asia.

If you mine, smelt, trade, or export metals and minerals from Malaysia or Singapore, your cargo insurance programme must address theft of high-value metals, corrosion and oxidation during ocean transit, weight and quantity disputes for bulk mineral shipments, and the critical safety risk of cargo liquefaction in bulk carriers. These are not generic cargo risks. Metals and minerals require underwriters who understand LME-priced commodities, bulk carrier operations, and the physical behaviour of mineral cargoes at sea.

Cargo Liquefaction: The Critical Risk for Mineral Concentrates

Cargo liquefaction deserves specific attention because it is a catastrophic safety risk unique to bulk mineral shipments. When a bulk cargo with high moisture content is subjected to the cyclic loading of wave action and vessel vibration, the cargo can transition from a solid to a liquid state. The liquefied cargo shifts rapidly in the vessel's hold, creating free surface effect that reduces the vessel's stability. If sufficient cargo shifts to one side, the vessel lists beyond the point of recovery and capsizes.

How Liquefaction Occurs

Insurance Implications of Liquefaction

Liquefaction incidents typically result in total loss of the vessel and all cargo on board. Cargo insurance under ICC (A) covers physical loss of the cargo, subject to policy terms and conditions. However, if the shipper knowingly loaded cargo with moisture content exceeding the TML, issues of wilful misconduct and breach of the IMSBC Code arise. Underwriters assess the shipper's testing procedures, the independence of the surveyor who certified moisture content, and compliance with the IMSBC Code as part of the risk evaluation.

Who In the Metals & Minerals Industry Needs Marine Insurance

Common Claims in Metals & Minerals Cargo

Claim 1: Corrosion of Steel Coils, Port Klang to Jebel Ali

A Malaysian steel manufacturer exports 500 tonnes of hot-rolled steel coils on a flat rack and in open-top containers from Port Klang to Jebel Ali, Dubai. During the 8-day voyage through the Strait of Malacca and across the Indian Ocean, sea spray and high humidity cause surface rust on approximately 30% of the coils. The buyer rejects the affected coils and claims for downgrading costs.

Claim 2: Theft of Copper Cathodes, Singapore Warehouse

A metals trading house stores 100 tonnes of copper cathodes in a Singapore warehouse pending onward shipment to a Chinese buyer. During a weekend, thieves breach the warehouse security and remove approximately 15 tonnes of copper cathodes, valued at approximately USD 135,000.

Claim 3: Liquefaction of Nickel Ore, Bulk Carrier

A bulk carrier loads 45,000 tonnes of nickel ore at a Southeast Asian port for delivery to a Chinese smelter. The ore was loaded during the monsoon season. During the voyage, the vessel encounters heavy weather in the South China Sea. The cargo, which had moisture content close to the transportable moisture limit, liquefies. The liquefied cargo shifts to the port side, causing the vessel to develop a severe list. The crew abandons the vessel, which subsequently capsizes. Total loss of vessel and all cargo.

Claim 4: Weight Dispute, Tin Ingots, Butterworth to Rotterdam

A Malaysian tin smelter exports 200 tonnes of refined tin ingots on CIF Rotterdam terms. Weighbridge certificates at origin show 200.0 tonnes. On arrival at Rotterdam, the buyer's weighbridge records 198.2 tonnes, a shortage of 1.8 tonnes (0.9%). At current tin prices, 1.8 tonnes of tin is valued at approximately USD 54,000. The buyer claims for the full shortfall.

How Incoterms Apply to Metals & Minerals Trade

The theft gap in CIF metals trade: Under CIF, the seller must insure to ICC (C) minimum, which does not cover theft. For high-value metals (copper, tin, aluminium), theft is a primary risk. Sellers should arrange ICC (A), and buyers receiving metals on CIF terms should verify the coverage level or arrange supplementary cover.

Frequently Asked Questions (FAQ)

What marine insurance do metals exporters need?

Metals exporters need marine cargo insurance under ICC (A) covering all risks of physical loss or damage during transit, subject to policy terms and conditions. ICC (A) is the broadest standard form and covers theft, corrosion, mechanical damage, and shortage. War risk (CL385) and strikes (CL386) extensions should be included for shipments to or through JWC listed areas. For regular exporters, an annual open cover facility provides automatic coverage.

Does marine cargo insurance cover corrosion of steel during ocean transit?

Yes, subject to policy terms and conditions. ICC (A) covers corrosion caused by external perils during transit, such as sea spray, container condensation, and humidity exposure. The insurer assesses whether adequate protective measures (VCI packaging, rust inhibitors, desiccants) were in place. Corrosion resulting from inherent vice (Clause 4.4), such as steel that was already showing rust at origin, may be excluded.

What is cargo liquefaction and does insurance cover it?

Cargo liquefaction occurs when bulk mineral cargoes with high moisture content transition from a solid to a liquid state under the dynamic loading of wave action and vessel vibration. Liquefied cargo shifts rapidly, destabilising the vessel and potentially causing capsize. ICC (A) covers physical loss or damage from liquefaction, subject to policy terms and conditions. The shipper's compliance with IMSBC Code moisture testing requirements and TML certification is a critical factor in claims assessment.

Is theft covered for metals stored in a warehouse during transit?

ICC (A) covers theft during the transit period, including storage in warehouses that falls within the warehouse-to-warehouse transit defined by the policy, subject to policy terms and conditions. ICC (B) and ICC (C) do not cover theft. Warehouse security measures, access controls, and surveillance systems are underwriting factors for metals stored in transit.

How are weight disputes handled in metals cargo insurance claims?

Weight disputes are common in bulk metals trade. ICC (A) covers genuine shortage, subject to policy terms and conditions. Normal trade allowances are deducted from any claim. The insurer investigates weighing methodology at loading and discharge, container seal integrity (for containerised metals), and whether any pilferage occurred. Independent surveying at both ends using consistent methodology is the foundation for resolving weight disputes.

Do I need marine cargo insurance for scrap metal imports?

Yes. Scrap metal faces contamination risk (hazardous materials mixed with scrap), fire risk (from reactive materials), and weight dispute risk. Marine cargo insurance under ICC (A) covers these perils, subject to policy terms and conditions. Scrap metal importers should also verify that their suppliers comply with Basel Convention requirements for cross-border movement of waste materials.

What is the IMSBC Code and why does it matter for mineral exports?

The International Maritime Solid Bulk Cargoes (IMSBC) Code classifies solid bulk cargoes and sets requirements for testing, documentation, and safe carriage. For cargoes that may liquefy (Group A cargoes), the IMSBC Code requires shippers to declare the moisture content and transportable moisture limit (TML). Non-compliance with the IMSBC Code can jeopardise insurance coverage and create criminal liability for shippers.

Does Singapore's role as an LME hub affect insurance for metals traded through Singapore?

Metals stored in LME-registered warehouses in Singapore and subsequently shipped to buyers are subject to the same transit risks as any other metals shipment. The storage period in the LME warehouse may fall within the transit policy's warehouse-to-warehouse coverage, subject to policy terms and conditions. Metals traders using Singapore as a trading hub should verify that their open cover facility covers storage in transit at Singapore warehouses.

Why Voyage for Metals & Minerals

Malaysia's metals and minerals sector spans tin smelting with decades of heritage, growing iron and steel exports, strategic rare earth processing, and aluminium production. Singapore complements this as a global metals trading and physical storage hub. Each shipment carries commodity-specific risks that generic cargo content does not address: theft of high-value metals from warehouses and trucking routes, corrosion of steel on tropical ocean transits, catastrophic liquefaction of mineral concentrates in bulk carriers, and weight disputes that can run to hundreds of thousands of dollars per shipment.
