Can I Send Lithium Batteries in the Mail? A Comprehensive Guide
Yes, you can send lithium batteries in the mail—but there are important rules and restrictions. Mailing lithium batteries is more complicated than shipping everyday items. Due to their chemical makeup, lithium batteries are considered hazardous materials by many postal and courier services. This means you need to follow specific guidelines to ensure safety, legal compliance, and successful delivery.
Let’s break down exactly how you can safely and legally mail lithium batteries, the challenges involved, best practices, and tips to manage costs.
Understanding Lithium Batteries: Why Are They Restricted?
Lithium batteries power a wide range of devices, from smartphones and laptops to power tools and electric bikes. There are two main types:
- Lithium-ion (rechargeable): Found in electronics like laptops, cell phones, and cameras.
- Lithium metal (non-rechargeable): Common in watches, hearing aids, and some small electronics.
Both types are popular due to their high energy storage and light weight. However, if damaged or improperly packed, lithium batteries can overheat, leak, or even catch fire. That’s why shipping carriers have strict regulations for mailing them.
Key Regulations for Mailing Lithium Batteries
When it comes to mailing lithium batteries, you must consider:
- Type of Battery: Lithium-ion or lithium metal, rechargeable or non-rechargeable.
- Battery Configuration: Are you mailing the battery by itself, or is it installed in a device?
- Battery Size (Watt-Hour Rating or Lithium Content): Larger batteries have more restrictions.
- Destination: Domestic (within the U.S.) versus international shipping.
- Carrier Policies: USPS, FedEx, UPS, and other couriers have unique rules.
Domestic Shipping (Within the U.S.)
You are generally allowed to ship lithium batteries within the U.S., but you must follow strict packaging, labeling, and quantity limits. See below for details on each major scenario.
International Shipping
Shipping lithium batteries internationally is much more restricted. Many carriers—including the USPS—prohibit certain batteries, especially loose ones (those not installed in devices), in international mail.
How to Mail Lithium Batteries: Essential Guidelines
1. Identify the Battery and Its State
- Installed in Equipment: Many carriers allow lithium batteries if they are installed in the device.
- Packed with Equipment: Batteries are not inside the device but in the same box.
- Batteries Alone (Loose/Spare Batteries): Subject to the strictest rules.
2. Packaging Requirements
Safe and compliant packaging is non-negotiable:
- Prevent Short Circuits: Cover battery terminals or keep batteries in original packaging.
- Separate Multiple Batteries: Ensure batteries do not touch each other or conductive materials.

3. Labeling and Marking
Shipping lithium batteries usually means you need to:
- Mark the package as containing lithium batteries (using the specific warning labels where needed).
- Mark the package “Surface Mail Only” for certain battery types (especially when mailing via USPS ground shipping).
4. Quantity and Size Limits
- Lithium-ion batteries: Limited by watt-hour (Wh) rating. Usually, 100 Wh or less per battery is allowed.
- Lithium metal batteries: Limited by lithium content (maximum 2 grams lithium per cell).
Packages exceeding these limits cannot be shipped by air and may be refused altogether.
5. Shipping Methods
- USPS: Permits shipping most lithium batteries within the U.S. under strict guidelines, but restricts shipments internationally (with few exceptions).
- FedEx/UPS: Also allow lithium batteries, but air shipment is highly regulated. Ground shipping is easier for most batteries.
- Always check with your chosen carrier before shipping.
