Lithium Batteries: Class 9 Doesn’t Mean Low Risk
When it comes to dangerous goods, Class 9 is often misunderstood. It’s the “miscellaneous” category yet within it lies one of the most volatile and strictly regulated items in global freight… lithium batteries.
At DG Solutions, we work with New Zealand exporters daily to ensure lithium battery shipments meet IATA and IMDG requirements. In this post, we’ll break down why lithium batteries are dangerous, where the risks lie and why compliance matters more than ever.
Why Are Lithium Batteries Dangerous?
Lithium batteries, both lithium ion (UN3480/UN3481) and lithium metal (UN3090/UN3091) are used in everything from laptops to e-bikes. But what makes them risky?
Thermal Runaway: A battery can overheat, catch fire, and explode if damaged, overcharged, or exposed to high temperatures.
Chemical Instability: If the internal separator fails, it can cause a short circuit leading to fire.
Cargo Contamination: A single faulty battery in a shipment can ignite other goods.
Despite being labelled Class 9, lithium batteries have fire risks comparable to flammable liquids, especially in bulk or when improperly packed.
Risks During Air and Sea Transport
Air and sea freight magnify the danger due to enclosed spaces, temperature fluctuations, and limited access during transit.
Air Freight Risks:
In flight fires: Lithium batteries have caused numerous cargo hold fires on aircraft.
FAA and ICAO now prohibit loose lithium metal and lithium ion batteries on passenger aircraft entirely.
Airlines require strict state of charge (SoC) limits, proper UN approved packaging, and specific documentation.
Sea Freight Risks
Fires onboard ships can be devastating due to the time needed to contain them.
Mis declared or improperly packed lithium battery cargo has been linked to several serious container ship fires.
Real Incidents That Changed the Industry
Here are some notable lithium battery incidents that led to global regulatory crackdowns:
UPS Flight 6 – Dubai, 2010
Two crew members died after a fire caused by lithium batteries in the cargo hold.
Led to stricter air cargo rules and packaging standards.
Asiana Airlines Flight 991 – South Korea, 2011
Lithium batteries and flammable liquids caused a mid air fire, resulting in a fatal crash into the sea.

Don’t Underestimate Class 9
Just because lithium batteries fall under Class 9 doesn’t mean they’re low risk. In fact, they’re one of the most closely watched dangerous goods classes in international trade. Whether you’re shipping by air or sea, regulatory compliance is essential, and a single mistake could cost you a shipment.. or worse.
