Why Declaring Lithium Batteries As Dangerous Goods Is Essential Before Shipping

Why Declaring Lithium Batteries as Dangerous Goods Is Essential Before Shipping

As a freight forwarder, I’ve seen a sharp rise in inquiries involving lithium batteries, energy storage systems (ESS), and battery-powered equipment. Many shippers are eager to move their cargo but aren’t fully aware that these items fall under Class 9 Dangerous Goods and require strict declaration and packaging procedures before being loaded onto a vessel or aircraft.

Neglecting this step not only increases the risk of accidents but also jeopardizes the entire supply chain.

Why Lithium Batteries Are Classified as Dangerous Goods

Lithium batteries carry a high energy density and are prone to thermal runaway, fire, or explosion if damaged, short-circuited, or exposed to high temperatures. Due to these risks, they are classified under UN3480 / UN3481 – Class 9 Dangerous Goods by the United Nations.

Here are some notable lithium battery-related incidents in recent years:

• 2022: Felicity Ace, a car carrier ship with EVs on board, caught fire and sank in the Atlantic Ocean.

• 2024: A lithium battery fire at a Korean factory killed 23 workers and injured 8.

• 2025: A fire broke out on an Air Busan aircraft, likely caused by a faulty battery pack.

Each case highlighted serious gaps in handling, packaging, or documentation of dangerous goods.

Key Declaration Steps Before Shipping Lithium Batteries

To ensure safe and compliant shipping, the following three steps must be completed before transport:

1. DG Declaration (Dangerous Goods Declaration)

• Identify the correct UN number, class, and net/gross weight.

• Submit a valid MSDS (Material Safety Data Sheet).

• Prepare a signed Shipper’s Declaration for Dangerous Goods form.

2. Proper Packaging

• Use packaging with UN certification, compliant with IATA or IMDG regulations.

• Ensure shock resistance, waterproofing, and insulation to prevent short circuits.

• Attach Class 9 and lithium battery warning labels, plus directional arrows if required.

3. Inspection and Stuffing (if full container)

• Some ports require a maritime authority inspection before loading DG containers.

• Appointed third-party inspectors will verify label accuracy, packing compliance, and monitor the stuffing process.

• A final inspection report may be required for shipping line documentation.

The Risks of Non-Declaration

Failing to declare lithium batteries as dangerous goods can lead to:

• Customs delays or cargo seizures

• Fire or explosion risks inside the container or aircraft

• Legal liabilities and high penalties

• Blacklisting by carriers or freight terminals

In some countries, even undeclared spare lithium batteries in passenger luggage have resulted in severe airline penalties and emergency landings.
