How Can You Ship Lithium Batteries via USPS?
Shipping lithium batteries through USPS is allowed under strict regulations to ensure safety. Batteries must be properly packaged, labeled, and meet quantity and watt-hour limitations. Redway Power emphasizes compliance with USPS guidelines and proper battery management systems to guarantee safe and efficient shipping.
What USPS regulations govern the shipping of lithium batteries?
The USPS follows Department of Transportation (DOT) and International Air Transport Association (IATA) regulations for lithium battery shipping. There are strict limits on battery types (lithium-ion and lithium metal), quantity (e.g., max 4 lithium cells or 2 batteries per package), and packaging requirements to prevent short circuits and fires.

How must lithium batteries be packaged for USPS shipping?
Lithium batteries must be packed to prevent movement, short circuits, and damage. This includes placing batteries in their original packaging or using insulating materials, placing packages in strong outer packaging, and ensuring no metal parts can cause shorting. Packages must also carry the appropriate UN hazard labels and markings.
What paperwork and labeling are required for shipping lithium batteries?
Packages containing lithium batteries require hazard labels indicating the UN number, proper shipping name, and emergency contact information. For international shipments, customs declarations and forms with battery details such as watt-hour rating and quantity are also mandatory.
Can you ship lithium batteries alone or only with equipment?
USPS allows shipping lithium batteries installed in or packed with equipment domestically. Individual batteries without equipment are generally restricted, especially internationally. Some small consumer lithium batteries are eligible for air shipment; others must be shipped by ground to comply with safety rules.
What are the quantity and watt-hour restrictions for lithium battery shipments?
For lithium-ion batteries, a maximum of 100 watt-hours per battery is allowed. Up to 4 lithium cells or 2 batteries can be shipped per package. Lithium metal batteries have stricter limits due to higher fire risk. Exceeding these limits requires special permits and packaging.

How do USPS restrictions affect international shipping of lithium batteries?
Many countries have additional restrictions; some ban lithium batteries or require advanced safety markings. USPS requires checking destination country rules and may limit lithium battery shipments internationally. Packages often must be shipped by surface transportation only.
