Lithium-ion batteries are now part of everyday business.

They are used in electric vehicles, energy storage systems, power banks, industrial equipment, electronics and many other products.

But when lithium-ion batteries are shipped by themselves, they are not treated as normal cargo.

They are generally classified as UN3480 - Lithium ion batteries and are subject to dangerous goods transport requirements.

For Indian manufacturers, importers and exporters, UN3480 shipping in India requires careful planning before the cargo reaches an airport, port or carrier.

A small mistake in battery classification, State of Charge, packaging or documentation can result in rejection, repacking or a missed shipment.

What Is UN3480?

UN3480 is the UN number used for lithium-ion batteries shipped by themselves.

This is different from UN3481.

UN3481 generally applies when lithium-ion batteries are packed with equipment or contained inside equipment.

For example, a carton containing only spare lithium-ion battery packs may fall under UN3480.

A laptop containing its battery would normally be treated under a different battery transport configuration.

Getting this distinction right is important because the packing instructions, labels and carrier acceptance requirements can differ.

Why UN3480 Shipping Is Important

Lithium-ion batteries can create fire and thermal runaway risks if they are damaged, incorrectly packed, defective or short-circuited.

Because of this, airlines and shipping lines apply strict controls.

For air transport in 2026, lithium-ion batteries shipped alone under UN3480 are not permitted as cargo on passenger aircraft. They must move on suitable cargo aircraft, subject to airline acceptance and applicable dangerous goods requirements.

This immediately changes the logistics plan.

An exporter cannot simply select the fastest passenger flight and assume the batteries can travel as normal cargo.

The route, aircraft type and carrier approval need to be checked first.

Who Needs UN3480 Shipping Services?

UN3480 shipping can be relevant for businesses dealing with:

• EV and automotive batteries
• Energy storage batteries
• Power banks
• Industrial battery packs
• Replacement lithium-ion batteries
• Electronics and battery distributors

Manufacturers importing battery cells for assembly may also need UN3480 logistics support.

For regular battery importers and exporters, having a standard shipping process can reduce repeated errors.

Start With the Battery Specifications

The first step is to understand exactly what battery is being shipped.

The logistics team should know the battery type, Watt-hour rating, quantity, weight and whether the battery has successfully completed the applicable UN38.3 testing.

Watt-hour rating is particularly important.

It can usually be calculated as:

Wh = Voltage x Amp-hour capacity

For example, a battery rated at 48 V and 20 Ah would have:

48 x 20 = 960 Wh

This is much higher than the 100 Wh threshold used in important parts of the air transport framework.

For UN3480 air shipments under IATA's 2026 guidance, batteries above 100 Wh fall under Packing Instruction 965 Section IA, while batteries not exceeding 100 Wh may fall under Section IB when the applicable conditions are met.

UN38.3 Testing

One of the most important requirements for lithium batteries is UN38.3 testing.

Lithium cells and batteries intended for normal transport generally need to have passed the tests specified under the UN Manual of Tests and Criteria, Part III, Subsection 38.3.

These tests cover risks such as altitude simulation, vibration, shock, external short circuit and other battery safety conditions.

Manufacturers and subsequent distributors are also expected to make the applicable UN38.3 test summary available for relevant lithium cells and batteries.

A common mistake is assuming that because a battery is commercially sold and working correctly, it is automatically suitable for international transport.

Commercial performance and transport compliance are different matters.

State of Charge for UN3480 Air Shipping

State of Charge is another critical requirement.

For UN3480 air transportation, lithium-ion cells and batteries must generally be offered for transport at a State of Charge not exceeding 30% of their rated capacity.

A battery above 30% State of Charge may require approval from the State of Origin and State of the Operator under the applicable conditions.

For example, if a battery has a rated capacity of 100 Ah, the shipper should not simply charge it fully before sending it to the airport.

The logistics and production teams need to coordinate the battery preparation before packing.

This is one reason battery shipping should be planned before the cargo is commercially ready.

Packaging Requirements

UN3480 batteries cannot be packed like ordinary spare parts.

The packaging must protect the batteries against movement, physical damage and short circuit.

Battery terminals may need to be protected so that accidental contact cannot occur.

The packaging method will depend on battery size, configuration, Watt-hour rating and the applicable packing instruction.

For larger batteries under PI 965 Section IA, UN specification packaging requirements can apply.

Correct marks and labels are also important.

For applicable UN3480 air shipments, packages may need the Class 9 lithium battery hazard label, Cargo Aircraft Only label and other required markings.

Packaging should therefore be checked before cargo reaches the airport.

Repacking lithium batteries after airline rejection can cause significant delay.

Air Freight Limits Matter

The amount of battery material inside one package can also affect the shipment.

Under the 2026 IATA guidance, UN3480 batteries above 100 Wh under PI 965 Section IA have a cargo-aircraft limit of 35 kg per package.

For batteries not exceeding 100 Wh moving under Section IB, the applicable cargo-aircraft limit is 10 kg per package. Passenger aircraft transport remains forbidden for UN3480 in these configurations.

This means a shipment of 200 kg of batteries cannot automatically be placed into one large export package.

The packing plan needs to reflect the applicable limits.

UN3480 Shipping Process

A professional battery shipment should follow a clear sequence.

First, confirm the battery type and technical specification.

Then review the Watt-hour rating and UN38.3 status.

After that, determine the correct packing instruction and check the State of Charge.

Packaging, marks and labels should be completed before airline or shipping-line acceptance.

The typical process is:

Battery Review -> UN38.3 Check -> Classification -> Packaging -> Carrier Approval -> Customs -> Air or Sea Freight -> Destination Clearance -> Final Delivery

The carrier should ideally be approached before the cargo is dispatched from the factory.

Important Documents

The exact document requirement depends on the mode, carrier and shipment configuration.

Common documents may include:

• Commercial Invoice
• Packing List
• Safety Data Sheet where relevant
• UN38.3 Test Summary
• Shipper's Declaration for Dangerous Goods for applicable air shipments
• Air Waybill or Bill of Lading
• Battery technical specification

The information across these documents should match.

If the invoice mentions one battery model while the UN38.3 summary covers another model, the shipment can face questions.

UN3480 by Sea Freight

Air freight is not the only option.

For larger battery shipments, sea freight may be commercially more practical.

From 1 January 2026, the IMDG Code 2024 Edition incorporating Amendment 42-24 became mandatory for dangerous goods carried in packaged form by sea.

Sea freight can be useful for regular imports, larger battery volumes and shipments where delivery is not extremely urgent.

However, shipping-line acceptance still needs to be confirmed.

One carrier may accept the battery cargo on a particular route while another may impose additional conditions.

The freight forwarder should therefore check the exact carrier, vessel service and transshipment route.

Case Study: One Battery Detail Delays the Shipment

Consider an Indian company exporting 20 lithium-ion battery packs.

Each battery is rated at 120 Wh.

The sales team books urgent air freight and prepares the cargo.

At the time of final review, the logistics team discovers that the supplier documentation was prepared as if the batteries were below 100 Wh.

The battery configuration actually falls into a different packing category.

The cargo now needs to be repacked and the dangerous goods documentation revised.

The planned flight is missed.

The mistake was not caused by the airline.

It started with incorrect battery data.

For UN3480 cargo, accurate technical information should therefore be confirmed before freight booking.

Common Challenges in UN3480 Shipping

One common problem is missing or incorrect UN38.3 documentation.

Another is incorrect Watt-hour information.

State of Charge can also create delays, especially when the production team prepares the batteries without considering air freight requirements.

Carrier restrictions are another challenge.

Even if the shipment is correctly prepared, not every airline or shipping line will accept the cargo on every route.

Damaged or safety-defective batteries create even more serious issues and may be prohibited from normal air transportation.

This is why the forwarder should understand the condition and purpose of the shipment before confirming space.

Benefits of Proper Battery Shipping Planning

Correct planning reduces the risk of cargo rejection and missed flights.

It also allows the shipper to compare air and sea freight properly.

For frequent battery shipments, businesses can maintain a compliance file containing battery specifications, Watt-hour ratings, UN38.3 summaries and approved packaging information.

This makes future shipments easier to prepare.

However, carrier requirements should still be checked for each booking.

How a DG Freight Forwarder Can Help

An experienced dangerous goods freight forwarder can help coordinate the technical and logistics requirements of the shipment.

This may include reviewing battery information, identifying the correct transport configuration, coordinating packaging, obtaining carrier acceptance, arranging Customs clearance and managing air or sea freight.

The forwarder can also help determine whether the shipment should move by cargo aircraft or sea freight based on urgency, volume and carrier availability.

For businesses importing batteries into India, the same partner can coordinate international freight, Customs clearance and final door-to-door delivery.

Conclusion

UN3480 shipping in India requires careful preparation because lithium-ion batteries shipped by themselves are treated as dangerous goods.

For air freight, UN3480 batteries cannot normally move as cargo on passenger aircraft. State of Charge, Watt-hour rating, UN38.3 testing, packaging and carrier acceptance all need to be checked before booking.

For larger shipments, sea freight may provide a practical alternative under the applicable IMDG requirements.

The most important rule for businesses is simple - do not treat lithium batteries as normal cargo.

Review the battery first, confirm the compliance requirements, and only then book the shipment.
