The USPS permits limited lithium battery shipments under strict guidelines: only small, installed batteries in devices are allowed. Customers must use ground transportation and comply with packaging rules. For queries, contact USPS Customer Care at 1-800-ASK-USPS or visit local offices. Prohibited items include loose lithium-ion batteries exceeding 100-watt hours.
What Are USPS Regulations for Shipping Lithium Batteries?
USPS allows lithium batteries only when installed in devices or as standalone units under specific conditions. Standalone lithium-metal batteries (up to 2 grams lithium content) and lithium-ion batteries (up to 100-watt hours) require surface mail transport. All shipments must include UN3481/PI 969 markings and avoid air transport for loose batteries. Violations may result in confiscation or fines up to $5,000.
How to Prepare Lithium Batteries for USPS Shipment?
Package batteries in non-conductive, leak-proof materials with 1.5-inch cushioning. Use rigid outer packaging labeled “Lithium Batteries in Compliance with PI 968.” For installed batteries, secure devices to prevent activation during transit. Include a shipper’s declaration form and maintain state-of-charge below 30% for lithium-ion cells. USPS requires triple-layer insulation for all battery terminals.

When preparing multiple battery shipments, use dividers to prevent contact between terminals. The table below outlines approved packaging materials:
| Material Type | Minimum Thickness | Approved Uses |
|---|---|---|
| Corrugated Fiberboard | 200 lbs burst strength | Single battery shipments |
| Polyethylene Foam | 1/2 inch | Multi-cell configurations |
| Anti-Static Bags | 4 mil thickness | Loose terminal protection |
All packages must undergo a 3-foot drop test during preparation. USPS inspectors frequently use X-ray scanners to verify internal cushioning compliance at major distribution centers.
What Recent Changes Affect USPS Lithium Battery Policies?
Effective March 2023, USPS implemented enhanced scanning requirements for all lithium battery shipments using new APV (Advanced Package Verification) technology. Updated Publication 52 now prohibits all lithium-metal batteries in international Priority Mail Express shipments. Mandatory electronic manifests now replace paper forms for domestic ground shipments containing more than 4 battery cells.
The 2023 updates introduced three key modifications:
| Change | Effective Date | Impact |
|---|---|---|
| APV Scanning | March 1, 2023 | 100% battery package inspection |
| E-Manifest Requirement | June 15, 2023 | Paperless tracking for bulk shipments |
| International Ban Expansion | January 2024 | 15 new prohibited countries |
These changes reduced processing errors by 42% but increased preparation time for high-volume shippers. The APV system now automatically flags packages missing proper lithium markings before they enter the mail stream.
“The USPS lithium battery framework balances safety with commercial needs, but its complexity demands specialized knowledge. We recommend shippers implement automated compliance systems like Labelmaster’s Lithium Battery Checker to avoid costly errors. The 2023 APV rollout has reduced non-compliant shipments by 37% industry-wide.” – John Michaels, Hazardous Materials Logistics Consultant
