UN3481 is one of those shipping terms that looks simple until you have to use it on a real package.
If you ship electronics, tools, devices, medical equipment, scanners, cameras, or other products powered by rechargeable lithium ion batteries, you may run into the UN3481 lithium battery label. More precisely, many regulations call it a lithium battery mark, but many people still search for it as a label.
The important thing is not what we call it in casual conversation. The important thing is knowing when it applies, what it means, and what to check before the package leaves your building.
This page is meant to help shipping, warehouse, ecommerce, repair, and operations teams understand the basics. It is not a replacement for current DOT, carrier, or air shipping requirements.
What Does UN3481 Mean?
UN3481 refers to lithium ion batteries that are packed with equipment or contained in equipment.
In plain English, that usually means the battery is shipped with a device, tool, product, or piece of equipment. The battery may already be installed in the item, or it may be packed in the same box with the item it powers.
UN3481 is different from UN3480. UN3480 is used for lithium ion batteries shipped by themselves, without equipment.
That difference matters. A box of loose rechargeable batteries is not the same as a laptop, tool, tablet, scanner, or electronic device with a battery installed or packed with it.
Why Lithium Battery Packages Need Clear Marks
Lithium batteries are common, but they are not treated like ordinary packaging material. They can create fire risks if they are damaged, packed poorly, short-circuited, overheated, or shipped under the wrong conditions.
That is why lithium battery marks exist. They help workers, carriers, and receiving teams see that the package contains lithium batteries and should be handled under the proper rules.
The label does not make the shipment compliant by itself. It is one part of a larger process that may include packaging, documentation, training, carrier rules, package limits, and shipment method.
UN3481 Packed With Equipment vs. Contained in Equipment
This is one of the most common points of confusion.
UN3481 packed with equipment
This means the lithium ion battery is packed in the same package as the equipment, but it is not installed in the equipment.
Example: a rechargeable tool packed in a box with a spare battery beside it.
UN3481 contained in equipment
This means the lithium ion battery is installed inside the equipment.
Example: a tablet, laptop, scanner, or electronic device shipped with the battery already inside it.
Both situations may use UN3481, but the packing rules and shipping details can still differ. That is why it is worth checking the exact situation before choosing a mark or preparing the shipment.
What Should a UN3481 Lithium Battery Mark Show?
A lithium battery mark commonly includes a battery symbol, red diagonal hatching around the border, and the correct UN number.
For lithium ion batteries packed with or contained in equipment, the mark should show UN3481.
Current U.S. rules describe the lithium battery mark as a rectangle or square with hatched edging. The symbols and letters are black on a white or contrasting background, and the hatching is red. The mark must also be large enough to fit properly on one side of the package without being folded.
Because rules can change, it is smart to check the current requirements before using old label stock. A good starting point is the PHMSA Lithium Battery Guide for Shippers. For the actual regulation text, see 49 CFR §173.185.
When Might a UN3481 Label Be Used?
A UN3481 lithium battery mark may be used when a package contains lithium ion batteries packed with equipment or contained in equipment.
Common examples may include:
- Rechargeable power tools packed with batteries
- Laptops and tablets
- Barcode scanners and handheld devices
- Medical or lab equipment with lithium ion batteries
- Cameras and video equipment
- Electronics repair returns
- Battery-powered commercial devices
- Equipment shipped with spare rechargeable batteries
The label should match what is actually inside the package. Do not use UN3481 just because the product is electronic. Check whether the battery is lithium ion, whether it is installed or packed with equipment, and whether the shipment meets the limits and rules for that method of transport.
Common Mistake: Using UN3481 When You Need UN3480
This mistake happens often.
If you are shipping lithium ion batteries by themselves, you may be looking at UN3480, not UN3481.
If the batteries are packed with equipment or contained in equipment, UN3481 may apply.
A simple way to think about it:
- UN3480: lithium ion batteries shipped by themselves
- UN3481: lithium ion batteries packed with or contained in equipment
This is not just a wording difference. It can affect how the package is prepared, marked, documented, and accepted by a carrier.
What to Check Before Shipping a UN3481 Package
Before a UN3481 package leaves your building, slow down and check the basics.
- Is the battery lithium ion?
- Is the battery packed with equipment or contained in equipment?
- Is UN3481 the correct UN number?
- Does the package need the lithium battery mark?
- Is the mark easy to see and not folded over an edge?
- Are the batteries protected from short circuit?
- Is the equipment protected from accidental activation?
- Does the package meet the quantity and weight limits for the shipment?
- Are you shipping by ground, air, vessel, or mail?
- Does your carrier have extra rules?
That last point matters. DOT rules are important, but carriers may have their own acceptance rules, forms, limits, or service restrictions.
Where to Place the UN3481 Label
Place the lithium battery mark on a flat, visible side of the package.
Try not to place it:
- Over a seam
- Around a corner
- Across tape
- On a damaged area of the box
- Where another shipping label covers it
- Where it may be folded or hard to read
A clear label helps the package move through the shipping process with less confusion. If the package is placed inside an overpack, check whether the lithium battery mark must also be visible or repeated on the outside of the overpack.
UN3481 Labels Are Not the Whole Shipping Process
A UN3481 lithium battery label helps identify the package, but it does not do the whole job.
The package may still need proper inner packaging, short-circuit protection, equipment protection, documentation, employee instruction, carrier approval, or other steps. Air shipments can also have extra rules.
For air shipping questions, the FAA’s Lithium Battery Resources page is a helpful place to start. It brings together lithium battery safety resources for air transportation.
Special Warning About Damaged, Defective, or Recalled Batteries
Do not treat damaged, defective, or recalled lithium batteries like normal battery shipments.
If a battery is swollen, leaking, overheating, recalled, damaged, or being returned because of a safety concern, it may need a different shipping process. These shipments can carry higher risk and may be restricted by mode of transport.
When in doubt, stop and check the current rules before shipping. This is one of those areas where guessing can cause real problems.
Quick Reminder Before You Label
UN3481 lithium battery labels are helpful because they make battery packages easier to identify. But the label is only one part of safe and correct shipping.
Before shipping, confirm the battery type, packaging method, shipment method, carrier rules, and current requirements for your exact situation.
The goal is simple: the right mark, on the right package, used for the right reason.
