How to Ship Lithium Batteries

Proper packaging and labeling are vital when shipping battery products internationally. Failure to do so could result in millions of dollars worth of damages.

Bookairfreight’s Key Takeaways:

• The packaging and labelling instructions for shipping electronics varies from air freight and ocean freight.

• You’ll need to get a UN38.3 test certification proof from your supplier in order to ship lithium battery products.

• Work with experienced freight forwarders to make sure your electronics get shipped safely.

First, Know if Your Device or Battery Is Classified as a ‘Dangerous Good’

All these super strict rules are applicable to Dangerous Goods (DG), which are goods with hazardous components - and often,  batteries are considered as DG.

How do you know if your battery is a DG?

All lithium batteries and devices with lithium batteries are considered to be hazardous! They are applicable to DG rules when shipping overseas.

There’s generally two types of lithium batteries:

Lithium-ion Batteries:
rechargeable batteries found in laptops, phones, cameras.
Lithium Metal Batteries:
non-rechargeable, disposable batteries found in watches, remotes.
lithium-batteries batteries

For each battery type, there is a specific UN Number, a four-digit number that identifies dangerous or hazardous substances and goods.

Shipping Name UN Number
Lithium-ion Batteries - Shipping Loose Batteries UN3480
UN3481 Lithium-ion Batteries Packed WITH or IN the device
Lithium-Metal Batteries - Shipping Loose Batteries UN3090
Lithium-Metal Batteries Packed WITH or IN the device UN3091

What types of batteries are not considered DG?

“Dry cell” batteries are not listed as DG or hazardous materials in the international regulations.

Common examples of Dry cell batteries include alkaline, nickel cadmium, and carbon zinc batteries.

So, You’re Shipping Lithium Batteries, What Should You Do Next?

1. Use proper labels

Make sure to check your specific freight carrier’s battery labeling requirements before shipping lithium batteries internationally.

But, here are the common rules that everyone must follow as authorised by the UN.

For ALL Lithium Battery Shipments Internationally (applicable for all transportation including air and ocean):

🚨 From January 2019, it is mandatory to apply:  

• Lithium battery label

• Class 9 lithium battery hazard class label

For Lithium-ion Battery Shipments by Air:

Lithium-ion batteries can only be shipped internationally on cargo aircraft (not allowed in passenger aircrafts anymore!), You need to apply:

• Lithium battery Label

• Class 9 lithium battery hazard class label

• Cargo aircraft only label.

2. Follow proper packaging


Packaging rules aren’t just about adding more protective layers of material or using the appropriate box. They also refer to weight, capacity restrictions, and the number of batteries allowed per internationally shipped goods:

General Packaging Rules:

How to pack lithium batteries to for shipping

1) For Loose Batteries: 

Require an additional layer of packaging -  such as insulated caps or leak-proof liner to prevent short circuits.

2) For Devices with Batteries:

Each device must be packaged individually with:

Non-conductive tape

An extra cushion layer to prevent the device from moving and accidentally turning on during handling.


We’ve listed out the packaging requirements for overseas air and ocean freight below, which your factories should be aware of. But it doesn’t hurt you to know them too!

✈️ Transporting lithium batteries by Air

The UN guidelines to ship battery products internationally depend on battery size and weight restrictions.

1) For Lithium-ion batteries - loose batteries (UN3480)

Packing instruction 965:

*packs refer to a set of multiple of identical batteries or battery cells.

2) For Lithium-ion batteries WITH and IN the device (UN3481)

Packaging instructions 966 and 967:

Max. Battery or Cell Size Weight or Number Restriction Additional Notes
Cell: 20 Wh or less

3) For Lithium-metal batteries - loose batteries (UN3090)

Packaging instruction 968:

• Lithium-Metal Content (LMC) must be 0.3g or less per unit.

• LMC must be 1g or less in cells

• LMC must be 2g or less per battery
• 2.5kg weight limit, No limit in number

• 8 cells

🚢 Transporting lithium batteries by Ocean

As mentioned earlier, the regulations for overseas shipping by ocean are a lot more relaxed.

The lithium batteries and cells must be packaged fully with a protective layer or non-conductive tape to prevent short circuits.

Labelling Requirements:

Each package must be marked with the

• Lithium Caution Label

• Hazardous class 9 Label

Lithium Metal Caution Label Lithium Ion Caution Label Hazardous Class 9 Label
lithium-batteries batteries batteries

3. Follow proper testing criteria

Lithium ion and Lithium-metal cells and batteries are listed as Class 9 Miscellaneous Dangerous Goods regulations - they must meet the UN38.3 test requirements set by the UN Manual of Tests and Criteria.

What is the "UN38.3 certification"?

It is a series of tests ranging from height simulation test, thermal test, vibration test, impact test, external short circuit test, to see if the goods are capable of being transported and used safely.

What does it look like?

It’s simply a test report. here's a UN38.3 certification:

UN38.3 certification for sending lithium batteries overseas

Who takes care of the testing?

Manufacturers or distributors of cells or batteries will take care of the test and attach the results to each shipment containing lithium batteries.

Once again, for all these requirements,  your factories must be aware and take care of them! So, don’t stress too much, this is just for your own reference.

Even if You Follow These Rules, It’ll Still Be Hard to Ship Electronics.


It really depends on the forwarder or carrier - they can refuse to take battery related overseas shipments anytime. So, you really need to work with experienced forwarders. 


Using Bookairfreight, you can partner with leading tier 1 freight forwarders who deeply understand what documentation is required for customs and how to best handle goods in transit for safe, timely delivery.
