Does the Post Office Accept Lithium Batteries for Shipping?

Yes, the post office accepts lithium batteries for shipping, but there are strict regulations and guidelines that must be followed. The U.S. Postal Service (USPS) allows certain types of lithium batteries to be shipped under specific conditions to ensure safety and compliance with hazardous materials regulations.

How Does the USPS Define Acceptable Lithium Batteries?

The USPS recognizes several types of lithium batteries that can be shipped, including:

• Lithium-ion batteries (UN3480) without equipment.
• Lithium metal batteries (UN3090) without equipment.
• Lithium-ion batteries contained in equipment (UN3481).
• Lithium-ion batteries packed with equipment (UN3481).
  These classifications determine how and under what conditions these batteries can be shipped.

What Are the Regulations for Shipping Lithium Batteries via USPS?

Shipping lithium batteries through USPS involves adhering to specific regulations:

• Only certain battery types are allowed, and they must meet size and weight restrictions.
• For lithium-ion batteries, each cell must not exceed 20 watt-hours (Wh), while lithium metal batteries must not exceed 2 grams of lithium content.
• Packages containing more than two lithium batteries or cells must be marked accordingly and may require special handling.

Why Is Proper Packaging Crucial When Shipping Lithium Batteries?

Proper packaging is essential to prevent short-circuiting, overheating, or potential fire hazards. The USPS requires that:

• Batteries are cushioned to avoid damage during transit.
• Packages include appropriate markings indicating they contain lithium batteries.
  Failure to package correctly can lead to shipment rejection or delays.

Where Can You Find USPS Guidelines for Shipping Lithium Batteries?

USPS provides detailed guidelines in their Publication 52, which outlines the requirements for shipping hazardous materials, including lithium batteries. This document includes information on acceptable battery types, packaging instructions, and labeling requirements.

When Should You Use Special Labels for Shipping Lithium Batteries?

Special labels are required when shipping lithium batteries to ensure compliance with safety regulations. Labels should indicate:

• The presence of lithium batteries in the shipment.
• Any specific handling instructions, such as “Surface Mail Only” if applicable.
  Using these labels helps postal workers handle packages appropriately and reduces the risk of accidents.

Who Can Assist with Shipping Lithium Batteries through USPS?

For assistance with shipping lithium batteries, customers can contact USPS customer service or visit their local post office. Postal employees can provide guidance on packaging requirements, labeling, and any specific questions regarding shipping policies.

Are There Specific Limitations When Shipping Lithium Batteries via USPS?

Yes, there are limitations when shipping lithium batteries. Some key restrictions include:

• Certain types of used or damaged batteries cannot be shipped via air transportation.
• There are limits on the number of cells or batteries that can be included in a single shipment (maximum of four cells or two batteries).
  Understanding these limitations is crucial to ensure compliance and avoid delays.
