Lithium-ion batteries require careful packaging to prevent the risk of fire and explosion during transport. Strict international regulations set out requirements regarding insulation, certified packaging and clear labelling. By adopting the right approach, you can ensure both safety and compliance.
Summary of this article
The packaging of lithium-ion batteries requires strict compliance with international safety regulations to prevent hazardous situations during transport. You must determine the correct UN classification, use certified packaging materials, insulate contact points, and apply all mandatory documentation and labelling. A professional packaging partner with expertise in dangerous goods transport ensures full compliance with ADR and IATA regulations.
Lithium-ion batteries pose a significant safety risk during transport due to their potential for thermal runaway, fire and explosion. If damaged, overheated or short-circuited, these batteries can cause dangerous situations that threaten lives and property.
The legal obligations under ADR regulations for batteries are strictly defined. All lithium-ion batteries fall under dangerous goods legislation and must be treated as Class 9 dangerous goods. This means you are obliged to follow specific packaging, documentation and transport procedures.
Incorrect packaging can lead to:
For defence and security organisations transporting sensitive equipment, correct battery packaging is essential for mission-critical operations. You can find more information on specialised defence packaging solutions from experts who understand military standards.
The main classifications for lithium-ion battery packaging are UN3480 (batteries only), UN3481 (batteries with or in equipment) and UN3171 (battery-powered vehicles). Each classification has specific packaging requirements and restrictions.
UN number Description Key requirements
UN3480 Lithium-ion batteries (only) Special provision 188, limited quantities
UN3481 Batteries with/in equipment Provision 230/188, less stringent requirements
UN3171 Battery-powered vehicles Special construction requirements
ADR regulations for road transport specify that batteries exceeding certain Wh capacities may only be transported in approved packaging. IATA regulations for air transport are even stricter, with restrictions on passenger flights and special handling procedures.
Other relevant standards include the UN Packaging Test Manual and the IMDG Code for maritime transport. These international standards ensure consistent safety levels worldwide.
The choice of UN3480 packaging depends on several critical factors. The battery type and Wh capacity determine which regulations apply. Batteries under 20Wh have less stringent requirements than larger ones.
Your transport method significantly influences the choice of packaging:
The destination country may impose additional requirements. Some countries have stricter import regulations or ban certain battery types entirely. Certified packaging materials must comply with UN test procedures, including drop tests, stacking tests and vibration tests.
Professional industrial battery packaging solutions combine compliance with practicality, with bespoke packaging offering optimal protection for specific battery configurations.
The safe battery packaging process begins with thorough preparation. Check the battery status, measure the voltage and inspect for damage. Damaged batteries must not be transported without special procedures.
Follow these essential steps:
Quality control is crucial. Test the packaging by shaking it gently and listening for moving parts. A correctly packaged battery should not make any noise when moved.
Mandatory transport documents for lithium battery transport include a dangerous goods declaration, in which you specify the UN classification, correct shipping name and total quantity. The consignor must sign a written declaration confirming correct packaging.
Essential labels and markings:
Traceability requires you to retain all documentation and be able to demonstrate that the batteries have been correctly classified and packaged. This is essential for compliance audits and in the event of any incidents.
The critical success factors for customised battery packaging are thorough knowledge of regulations, the use of certified materials and consistent application of procedures. Staff training is essential for safe handling.
Common mistakes include insufficient insulation of contact points, the use of non-approved packaging materials and incorrect documentation. These errors can lead to hazardous situations and compliance issues.
The importance of professional packaging partners is growing as regulations become more complex. Experts in industrial custom packaging can deliver end-to-end solutions that meet all international standards, from engineering to production and logistics.
For organisations that regularly transport lithium-ion batteries, working with specialist packaging experts provides certainty regarding compliance, safety and operational efficiency. This is particularly crucial for sectors where reliability and safety are non-negotiable.
When packaging lithium-ion batteries, a strong case or box alone is not enough. The right solution depends on factors including the type and condition of the battery, the mode of transport and the regulations that apply to the shipment. Faes therefore starts by defining the technical and operational requirements before selecting or developing a packaging solution.
Our engineers assess how the battery could move during transport, where mechanical loads may occur and which measures are needed to prevent damage, contact between terminals and short circuits. The positioning of the battery, the separation of individual components and the combination of outer packaging, interior and protective materials are also evaluated as a single system.
Based on this assessment, Faes selects an existing packaging solution or develops custom packaging. We consider not only protection, but also handling, reuse, weight and how the packaging will be used throughout the logistics chain. This prevents a packaging solution from meeting standard requirements while still being unnecessarily heavy, complex or prone to errors in day-to-day use.
When testing or certification is required, Faes can help prepare and coordinate the process. We translate the relevant requirements into concrete design specifications, incorporate test results into the design and support the documentation needed for a demonstrably substantiated packaging solution. Classification, packaging, marking and documentation must be properly aligned; correct packaging alone does not automatically make a shipment ready for transport.
In this way, Faes combines packaging development, custom engineering and support throughout the testing and certification process. The result is not a generic package for lithium-ion batteries, but a solution tailored to the battery, the associated risks and the conditions under which it will be transported.

Basic training in lithium-ion battery packaging usually takes 1–2 days, depending on the complexity of the battery types you are transporting. For defence and industrial applications, we recommend additional practical training of 4–8 hours. Regular refresher courses (annually) are essential as regulations change frequently.
Stop the transport immediately and isolate the packaging in a safe, ventilated area. Contact a certified hazardous materials specialist who can safely remove the battery. Damaged batteries require special procedures under UN3480 Special Provision 376 and must never be shipped via standard transport channels.
Yes, but only under strict conditions. All batteries must have the same UN classification and the total capacity must not exceed the permitted limits. Each battery must be individually isolated and protected. For complex combinations, we recommend professional advice to ensure compliance.
The costs vary between €15–50 per battery for standard packaging, depending on size and complexity. Bespoke industrial packaging costs €100–500 per solution. Although this may seem like an investment, it helps you avoid fines (€5,000–25,000), transport refusals and potential liability claims, which are far more costly.
Check the UN certification on your packaging materials and compare it with the latest ADR/IATA updates. Certifications have a limited validity and must be renewed regularly. A quick check: if your certification is more than two years old, have it assessed by a specialist to ensure it is up to date.
Defence equipment often requires additional military standards (MIL-STD) on top of civil regulations. Batteries must be able to withstand extreme conditions and have EMI protection. Custom packaging with special foam inlays and climate-resistant materials is usually necessary for mission-critical equipment.
ADR regulations are revised every two years, whilst IATA regulations are updated annually. Subscribe to official updates from transport authorities or work with a packaging partner that offers compliance monitoring. Many companies encounter problems because they continue to use outdated procedures – regular updates are crucial for compliance.
