How Does USPS Handle Lithium Batteries in Shipments?
Shipping lithium batteries through the United States Postal Service (USPS) is governed by strict regulations aimed at ensuring safety and compliance. Understanding how USPS handles these shipments is crucial for anyone looking to send devices powered by lithium-ion or lithium metal batteries.
What are the requirements for shipping lithium batteries via USPS?
USPS has established specific requirements for shipping lithium batteries, which include adhering to guidelines set forth in Publication 52. These guidelines specify that only certain types of lithium batteries can be mailed, such as those contained in or packed with equipment. Additionally, shippers must ensure proper labeling and packaging to comply with hazardous materials regulations.
How does USPS classify different types of lithium batteries?
USPS classifies lithium batteries into several categories based on their configuration and usage:
- Lithium-ion battery (UN3480): Shipped without equipment.
- Lithium metal battery (UN3090): Shipped without equipment.
- Lithium-ion battery contained in equipment (UN3481): Shipped with equipment.
- Lithium-ion battery packed with equipment (UN3481): Shipped alongside the device it powers.
- Lithium metal battery contained in equipment (UN3091): Shipped with equipment.
- Lithium metal battery packed with equipment (UN3091): Shipped alongside the device it powers.
Understanding these classifications helps shippers determine what can and cannot be sent through USPS.
What packaging guidelines must be followed for lithium batteries?
Proper packaging is critical when shipping lithium batteries. The following guidelines must be adhered to:
- Use strong outer packaging that can withstand transit.
- Ensure that terminals are protected against short circuits.
- Include appropriate hazard markings, such as “Surface Mail Only” if applicable.
- Comply with weight limits and quantity restrictions set by USPS.

Terminal Protection | Prevent short circuits |
Hazard Markings | Include specific labels as per regulations |
What are the restrictions for mailing lithium batteries with USPS?
USPS imposes several restrictions on mailing lithium batteries:
- Fully regulated (Class 9 labeled) batteries cannot be shipped.
- UN3480 and UN3090 cannot be mailed internationally.
- UN3481 and UN3091 in “packed with” configuration cannot be sent internationally.
These restrictions ensure that potentially hazardous materials do not pose risks during transport.
How should lithium batteries be packaged for safe shipment?
To package lithium batteries safely, follow these steps:
- Ensure that all battery terminals are insulated to prevent short circuits.
- Use cushioning materials to protect against impact during transit.
- Clearly label packages according to USPS requirements, including any necessary hazard warnings.
- Adhere to weight limits; typically, packages should not exceed 11 lbs.

Insulation | Insulate terminals to prevent short circuits |
Cushioning | Use protective materials against impact |
Labeling | Include required hazard warnings |
What are the limitations for international shipments of lithium batteries?
When shipping internationally, specific limitations apply:
- Lithium metal and ion cells must be properly installed in equipment.
- Maximum limits include four cells or two batteries per shipment.
These restrictions vary based on destination country regulations, making it essential to check local laws before shipping.
How does USPS handle damaged or defective lithium batteries?
USPS prohibits the mailing of damaged or defective electronic devices containing or packaged with lithium batteries. Such items must be marked as “Restricted Electronic Device” and shipped via surface transportation only. This policy helps mitigate risks associated with potentially hazardous materials.
