New Guidance Released on Lithium Battery Transport Safety

Global aviation regulators have issued updated operational guidance on the safe transport of lithium batteries, reinforcing industry focus on one of the most persistent cargo-related safety risks in modern air transport.

The new guidance, published jointly by the International Civil Aviation Organization and the International Air Transport Association, aims to strengthen procedures for the handling, packaging and declaration of lithium battery shipments across both passenger and cargo aircraft operations.

Lithium batteries are widely used in consumer electronics, electric mobility devices and industrial equipment. However, their potential to enter thermal runaway if damaged, improperly packaged or short-circuited has made them a significant safety concern for airlines, cargo operators and regulators.

The updated guidance places particular emphasis on improved shipper declarations, enhanced cargo screening procedures and clearer separation requirements when lithium batteries are transported in bulk.

Regulators are encouraging operators to adopt a more structured risk-based approach to battery shipments, including the integration of cargo hazard identification within airline Safety Management Systems frameworks. This includes improved reporting of undeclared dangerous goods and stronger training requirements for cargo acceptance personnel.

Industry safety bodies have repeatedly warned that undeclared lithium batteries remain a major risk within global cargo networks, particularly as e-commerce volumes continue to expand.

Airlines are also being urged to enhance flight crew awareness of lithium battery-related hazards. Updated recommendations include improved cockpit procedures for identifying potential cargo fires and updated guidance on the use of onboard fire suppression equipment.

Aircraft manufacturers have introduced a range of fire-resistant cargo container designs and improved cargo compartment fire suppression systems in recent years. Nevertheless, regulators emphasise that prevention at the shipping and handling stage remains the most effective safety measure.

The timing of the updated guidance reflects a broader increase in global air cargo activity. Demand for rapid transport of electronics, batteries and battery-powered equipment has grown significantly in recent years, particularly with the expansion of electric mobility products and consumer technology markets.

Industry experts note that as battery energy density continues to increase, the associated risk profile also evolves, requiring continual regulatory adaptation and operational vigilance.

Airlines and cargo operators have broadly welcomed the updated framework, viewing it as a necessary step toward harmonising global safety standards and strengthening compliance across the supply chain.

Regulatory bodies stress that while the transport of lithium batteries is well understood, consistent adherence to safety protocols remains critical.

With the aviation industry increasingly reliant on the rapid global movement of high-value electronics and energy storage systems, ensuring safe and compliant battery transport is expected to remain a central focus for regulators and operators alike.
