What is the new rule for lithium batteries?
New lithium battery regulations effective in 2025 focus on safety certifications, transportation protocols, and export controls. Key updates include mandatory CCC certification for e-bike batteries (effective Nov 1, 2025), 30% charge limits for air transport (effective Jan 1), UN3556 classification for battery-powered vehicles, and export restrictions on advanced lithium extraction technologies. These rules address fire risks, supply chain transparency, and intellectual property protection.

What are the key transportation changes for lithium batteries?
Three major transportation updates took effect in 2025: 1) Air cargo requires lithium batteries at ≤30% state of charge (SOC), 2) Maritime shipping must follow JT/T 1543-2025 safety standards, and 3) Battery-powered vehicles now use UN3556/9 classifications. Pro Tip: Shippers must update MSDS sheets before April 30 to avoid customs delays.
For air transport, the 30% SOC rule applies to both loose and installed batteries in devices—exceptions exist for medical equipment with special permits. Maritime regulations now require explosion-proof battery compartments and real-time temperature monitoring during ocean transport. A cargo ship carrying 20 tonnes of NMC batteries from Shanghai to Rotterdam, for instance, must install thermal runaway detection systems meeting JT/T 1543 standards. Warning: Non-compliant shipments face 200-500% penalty fees based on cargo value.
| Transport Mode | Key Requirement | Enforcement Date |
|---|---|---|
| Air | Max 30% charge | Jan 1, 2025 |
| Maritime | Thermal monitoring | May 1, 2025 |
| Land | UN3556 labeling | Jan 1, 2025 |
How does CCC certification impact e-bike batteries?
Mandatory CCC certification for all e-bike lithium batteries takes effect November 1, 2025. Manufacturers must pass 12 safety tests including overcharge protection and crush resistance. Batteries failing any test face immediate production halts.
The certification process requires third-party lab verification of 18 performance parameters—a typical 48V 20Ah battery undergoes 200+ charge cycles during testing. Retailers clearing existing stock must attach temporary compliance labels by October 31. A major Shanghai e-bike factory recently recalled 12,000 units after failing the new 1,000N mechanical stress test. Pro Tip: Exporters should request CCC documentation 6 months before shipment to avoid border rejections.

FAQs
Only commercial shipments are affected—consumer devices like laptops remain exempt from SOC limits during air travel.
Can certified batteries be modified post-production?
No—any firmware update or hardware alteration voids CCC certification immediately.
How long does CCC testing typically take?
8-14 weeks depending on battery type, with fast-track options available for an additional 50% fee.
