Moving military-related cargo through commercial supply chains presents a complex combination of safety, security, regulatory and political challenges, according to insurer TT Club.

The specialist nature of such cargo is becoming increasingly important as defence spending rises and more military cargo passes through commercial freight forwarders, road hauliers, port operators and shipping lines.

Weapons systems, munitions, missiles, propellants, grenades and component parts can move between manufacturers, storage facilities, ports and end users worldwide. Many fall within Class 1 dangerous goods, with the risks varying significantly by classification. Class 1.1 products present a mass-explosion hazard, while 1.4S articles are designed so that hazardous effects remain largely confined within the packaging.

Classification can affect transport costs, routing options and regulatory obligations, while misdeclaration can have severe consequences. Movements must also comply with dangerous-goods regulations, export, transit and import licences, trade controls and, in some cases, political approvals.

Security requirements can extend well beyond those normally associated with commercial freight, including continuous surveillance, security-cleared personnel, signature controls, detailed tally records and chain-of-custody documentation.

Explosive-quantity limits can require cargo to be split or segregated, while commercial ports rarely permit explosives to be stored before loading or after discharge. Direct delivery to and collection from ships therefore places additional pressure on certified vehicles and specialist drivers.

During mobilisation, higher volumes can create congestion across ports and hinterland networks, while ADR-qualified drivers and secure temporary storage may become scarce.

“Military-related cargo cannot be treated as simply another category of dangerous goods,” says Mike Yarwood, TT Club’s managing director, Loss Prevention. “Every movement demands detailed advance planning, specialist knowledge and close coordination between shippers, carriers, ports, authorities and insurers. A failure at any point in the chain – from classification and documentation to security arrangements or licensing – can have serious safety, legal and commercial consequences.”

Most military cargo moves by sea and road, with air transport generally reserved for urgent or operational requirements. Larger volumes may be moved by chartered vessels, offering greater flexibility and access to ports with higher explosives limits.

Illegal trade, sanctions violations and export-control breaches can carry significant legal and financial consequences and may prejudice the availability of insurance cover.
