Shipping Lithium Batteries Guide
Shipping lithium batteries requires meticulous planning and strict compliance with dangerous goods regulations. Because these products are classified as hazardous materials, every step of the process—from packaging design and labeling to carrier selection and documentation—must follow international standards such as UN, IATA, ICAO, ADR, and IMDG.
This article provides a practical, in-depth guide to safely shipping lithium batteries. We will walk through key packaging guidelines, labeling and documentation rules, transport mode differences (air, sea, and road), and best practices for working with carriers and freight forwarders, helping you move lithium batteries safely, legally, and efficiently.
Part 1. Shipping lithium batteries regulations and guidelines
Shipping lithium batteries requires strict adherence to international and national regulations to ensure safety, reduce fire and explosion risks, and maintain full legal compliance. Because lithium-ion and lithium-metal batteries are classified as dangerous goods, every shipment must follow clearly defined rules issued by bodies such as the International Air Transport Association (IATA), the International Maritime Dangerous Goods (IMDG) Code, and federal regulators like the U.S. Department of Transportation (DOT).
Overview of Shipping Regulations
Lithium battery shipping regulations operate on two levels: international frameworks and country-specific laws. At the global level, standards such as UN38.3 define mandatory safety tests, while IATA Dangerous Goods Regulations (DGR) and the IMDG Code set detailed requirements for air and sea transport, including packaging, labeling, state-of-charge limits, and documentation. National authorities—such as DOT in the United States and equivalent agencies in other countries—then incorporate these frameworks into their own transport rules for road, rail, air, and sea. Together, these regulations form a unified system designed to ensure that lithium batteries are handled, packed, declared, and shipped in a way that protects people, property, and the environment.
How do you package lithium-ion batteries for shipping?
Packaging lithium-ion batteries starts with one core principle: prevent short circuits, physical damage, and thermal events under normal transport conditions. To achieve that, you need the right combination of certified packaging, internal protection, and compliant labeling.
1. Choose suitable, compliant packaging
Use packaging that is specifically appropriate for lithium batteries and, where required, UN-tested and certified for dangerous goods. In practice, this means:
- A rigid outer carton made of sturdy, impact-resistant material
- Non-conductive inner trays, sleeves, or inserts
- Space for proper cushioning without crushing the cells or packs
For fully regulated shipments, the outer packaging must meet the performance standards specified in the applicable UN, IATA, or IMDG packing instructions.
2. Insulate and secure each battery
Every battery must be protected so that terminals cannot touch anything conductive or each other. Good practices include:
- Covering terminals with caps, insulating tape, or protective boots
- Using individual inner boxes, blister trays, or bags to separate units
- Filling voids with cushioning material to prevent movement and vibration
The goal is to ensure that even if the carton is dropped or stacked, the batteries remain mechanically stable and electrically isolated.
3. Maintain packaging integrity and drop resistance
The completed package must be strong enough to withstand normal handling, stacking, and minor impacts without deforming or exposing the batteries. That means:
- No overfilling or bulging cartons
- Proper sealing with strong tape on all seams
- Using pallets and strapping for bulk shipments to avoid crushing at the bottom layers
If the box cannot reliably survive a typical warehouse and linehaul environment, it’s not suitable for lithium batteries.
4. Apply correct labels and marks
Once packed, the package must be clearly and correctly labeled according to the shipment type and mode of transport. This usually includes:
- The correct UN number (e.g., UN3480, UN3481)
- The lithium battery mark and, where required, the Class 9 hazard label
- Any additional marks such as “Cargo Aircraft Only”, orientation arrows, or “Overpack” if applicable
Labels must meet size, color, and placement rules in IATA/ICAO, IMDG, ADR, and local regulations. Proper labeling is as important as the packaging itself—without it, the shipment is not legally compliant, even if the packing is technically sound.
Part 2. Lithium battery shipping label and documentation
- Lithium battery shipping label
A compliant lithium battery shipping label makes it immediately clear that the package contains regulated dangerous goods and explains how it must be handled. A proper label typically includes:
- “Lithium battery” identification
Clear wording such as “Lithium-ion batteries” or “Lithium-metal batteries” and, where required, the correct UN number (for example, UN3480, UN3481, UN3090, or UN3091) so carriers and inspectors can identify the exact battery type. - Pictograms and hazard labels
Standardized symbols and, when applicable, the Class 9 hazard label communicate key risks such as fire, short circuit, or thermal runaway. These visual cues help handlers recognize that the shipment requires special care, even if they do not read the full documentation. - Handling instructions
Warnings such as “Handle with care,” “Do not load in passenger aircraft,” or “Do not damage or crush” guide safe handling, storage, and loading. These instructions help prevent rough treatment, stacking errors, or exposure to heat sources. - Emergency contact information
A 24-hour emergency telephone number gives carriers and emergency responders a direct point of contact in case of damage, leakage, overheating, or fire. The contact person must be able to provide technical and safety guidance about the batteries shipped.
Correct, durable labeling is essential so that everyone in the supply chain—warehouse staff, ground handlers, customs officers, and emergency services—can quickly recognize, assess, and handle lithium battery shipments safely.
- Lithium battery shipping documentation
In addition to physical labels on the package, lithium battery shipments require a complete set of documents to prove compliance and support customs clearance and carrier acceptance. Typical documentation includes:
- Dangerous goods / shipping declaration
A formal declaration (for example, the Shipper’s Declaration for Dangerous Goods in air transport) that provides detailed information on the batteries, including UN classification, packing instruction, quantity, packing method, and confirmation that all applicable regulations have been met. - Safety Data Sheets (SDS)
An SDS describes the chemical and physical hazards of the battery, along with handling, storage, transport, and emergency response measures. Carriers, warehouses, and emergency services rely on this document to understand the risks and appropriate mitigation steps. - Customs declarations
For international shipments, accurate customs documentation must list the contents, HS codes, declared value, and any applicable duties, taxes, or export controls. Incorrect or incomplete declarations can lead to delays, inspections, or fines. - Transport documents
Documents such as air waybills, bills of lading, or CMR notes specify the chosen transport mode, carrier details, routing, and tracking references. These documents link the physical shipment to its regulatory status and supporting paperwork.
Together, the shipping label and documentation form the compliance backbone of any lithium battery shipment. They ensure that the cargo is correctly identified, legally declared, and safely handled from the factory floor to the final destination.
Part 3. Transportation methods and restrictions
1. Air freight
Air transport is the most tightly regulated mode for lithium batteries because of the fire risk in aircraft cabins and cargo holds. Shippers must comply with ICAO / IATA Dangerous Goods Regulations as well as airline-specific variations.
Key restrictions and requirements include:
- State of charge limits
- Standalone lithium-ion batteries (UN3480) shipped by air are generally limited to max. 30% state of charge (SoC).
- Aircraft type limitations
- Certain configurations of lithium batteries may be accepted only on cargo aircraft and must display the “Cargo Aircraft Only” label.
- Documentation
- Shipper’s Declaration for Dangerous Goods: Details battery type, UN number, packing instruction, quantity, and confirmation of regulatory compliance.
- Air Waybill (AWB): Lists shipper, consignee, routing, and tracking details, and links the shipment to the dangerous goods declaration.
- Packing List: Breaks down the contents, including battery models, quantities, and any equipment they are packed with or contained in.
- Safety Data Sheets (SDS): Provide hazard information and emergency response guidance for ground handlers and airline safety teams.
Because air rules are updated frequently, shippers should always reference the current IATA DGR edition before dispatch.
2. Sea freight
For ocean transport, lithium batteries are regulated under the IMDG Code, which aligns with UN dangerous goods recommendations but adds maritime-specific requirements.
Key points include:
- Dangerous goods declaration
- IMDG Dangerous Goods Declaration: Specifies UN number, proper shipping name, class, packing group (if applicable), and packing method.
- Transport documents
- Bill of Lading (B/L): Confirms receipt of the cargo by the carrier and includes details of shipper, consignee, container numbers, and voyage.
- Packing Certificate: Confirms that the container or vehicle was packed and secured in accordance with IMDG Code requirements (including segregation, blocking, and bracing).
- Safety documentation
- Safety Data Sheets (SDS): Support vessel operators and port authorities in risk assessment and emergency planning.
- Stowage and segregation
- Lithium batteries must be stowed away from heat sources, and in some cases segregated from incompatible goods, depending on the IMDG stowage and segregation provisions.
Sea freight is often preferred for large-volume or high-capacity battery shipments, but only when fully compliant with IMDG packing, marking, and stowage rules.
3. Land freight
Road and rail transport of lithium batteries is governed by frameworks such as ADR (in Europe), 49 CFR (in the United States), and equivalent regulations in other regions.
Typical requirements include:
- Transport contracts and responsibilities
- A transportation contract or carrier agreement defines responsibilities for loading, securing, documentation, and incident response.
- Shipping manifest / load list
- A shipping manifest details all items in the vehicle or container, including UN numbers, battery types, and quantities, helping both drivers and inspectors verify compliance.
- Safety documentation
- Safety Data Sheets (SDS) must be accessible to drivers and emergency responders in case of accidents, fires, or spills.
- Customs and cross-border paperwork
- For international land transport, customs declarations and, where applicable, TIR/CMR or local equivalents are required to move batteries legally across borders.
- Route and tunnel restrictions
- Some countries apply tunnel and route restrictions for certain dangerous goods loads, so routing must be planned in line with ADR or national rules.
Across all three modes—air, sea, and land—the core principles remain the same: correct classification, compliant packaging, accurate labeling, and complete documentation are essential to move lithium batteries safely and legally.

Part 6. FAQs
What are the rules for shipping lithium-ion batteries?
Rules depend on the transport mode (air, sea, road) and the countries involved, but the core requirements are similar everywhere. Lithium-ion batteries must be:
- Correctly classified (e.g., UN3480, UN3481)
- Packed in tested, non-conductive, and shock-resistant packaging
- Marked with the correct UN number and lithium battery labels
- Accompanied by proper dangerous goods documentation (e.g., IATA DGR, IMDG, ADR, 49 CFR)
Authorities such as IATA, ICAO, IMDG, and DOT define detailed limits on state of charge, quantity per package, and whether they can fly on passenger or cargo aircraft.
Can you mail lithium batteries internationally?
Yes, lithium batteries can be shipped internationally, but only under strict conditions. Key points include:
- Some postal operators ban standalone lithium batteries, especially by air
- Many carriers allow only batteries contained in or packed with equipment
- There are limits on watt-hours, lithium content, quantity, and state of charge
- Packaging, labels, and documents must follow IATA, IMDG, and local regulations
Before mailing, always check both the destination country’s rules and the carrier or postal service policy.
What are FedEx’s rules for shipping lithium batteries?
FedEx follows IATA Dangerous Goods Regulations for air and applicable international/national rules for ground and ocean. In practice, this means:
- Only certain lithium battery types and configurations are accepted

Can I ship lithium batteries with DHL?
Yes, DHL accepts lithium battery shipments, but under tight control:
- All batteries must comply with UN38.3 and relevant transport regulations
- DHL applies IATA DGR for air, IMDG for sea, and regional rules for road
- There are restrictions on standalone batteries vs. batteries in equipment
- Correct packaging, labeling, and documentation are mandatory
- Certain routes and products may be refused due to risk level
Always review DHL’s latest lithium battery policy and confirm acceptance before shipping.
Why can lithium batteries be difficult or restricted to ship?
Lithium batteries are not banned, but they are tightly regulated because they can:
- Overheat or enter thermal runaway
- Cause fires or explosions if short-circuited, damaged, or improperly charged
- Create severe risk in aircraft cargo holds or confined spaces
To control these risks, regulators require special packaging, clear hazard communication, UN testing, and trained staff. If these conditions are not met, carriers and authorities may refuse or stop the shipment, which is why it can seem like lithium batteries “cannot be shipped” in some cases.
