Starting 1 January 2026, the International Air Transport Association (IATA) requires that lithium-ion batteries, whether shipped loose or contained in devices, must have a maximum state of charge (SoC) of 30%. This change impacts OEMs and logistics providers worldwide, ensuring safer air transport and reducing the risk of battery-related incidents during shipping.
What Are the Key Changes in IATA Battery Regulations?
Previously, the 30% SoC limit applied only to loose lithium-ion batteries. From 2026 onward, this requirement also applies to batteries installed in devices or shipped with equipment. Manufacturers and retailers must adapt production, packaging, and logistics processes to comply with these stricter standards.
How Will Packaging Instructions Be Affected?
The new regulations update several packaging instructions:

| Packaging Instruction | Until 31 Dec 2025 | From 1 Jan 2026 |
|---|---|---|
| PI952 – Vehicles powered by batteries | SoC < 30% recommended | Vehicles >100Wh: SoC < 30% mandatory; Vehicles <100Wh: SoC < 30% recommended |
| PI965 – Batteries shipped alone | SoC < 30% mandatory | No change |
| PI966 – Batteries packed with equipment | SoC < 30% recommended | SoC < 30% mandatory |
| PI967 – Batteries contained in equipment | SoC < 30% recommended | No change |
These updates ensure that batteries transported by air meet uniform safety standards regardless of how they are packaged or installed.
Who Must Comply With the New Rules?
All producers, OEMs, and equipment manufacturers who ship lithium-ion batteries via air are required to comply. This includes batteries shipped separately, as part of a device, or packed with appliances. Extended producer responsibility applies, making compliance critical to avoid regulatory penalties and shipment delays.

How Can Companies Prepare for Compliance?
Companies should:
-
Adjust production lines to limit the state of charge to 30% before shipping.
-
Update packaging and labeling processes according to PI952–967 requirements.
-
Train logistics teams on new handling protocols for batteries in devices and equipment.
-
Collaborate with experienced battery suppliers like Redway Battery to integrate compliant shipping practices efficiently.
Proactive adaptation ensures smooth supply chain operations and avoids costly delays or regulatory issues.
Why Is Safe Transport Important?
Limiting the SoC of lithium-ion batteries reduces the risk of thermal runaway, fire, and damage during air transport. Safe transport is critical for both passenger and cargo flights, protecting employees, carriers, and end users while aligning with global safety standards.

Full guidance on logistics and documentation for OEMs and distributors.
This ensures clients remain compliant without disrupting existing operations.
Conclusion
The 2026 IATA lithium battery regulations mark a critical shift in air transport safety. Companies shipping batteries must adapt production, packaging, and logistics to maintain a maximum SoC of 30%. Working with experienced partners like Redway Battery provides reliable compliance solutions, minimizes risks, and ensures smooth global distribution.
FAQs
What is the maximum state of charge for lithium-ion batteries in air transport?
All batteries, loose or contained in devices, must not exceed 30% SoC from 1 January 2026.
Do these rules apply to batteries installed in devices?
Yes. Batteries shipped with appliances or installed in devices must also comply with the 30% SoC limit.
Which packaging instructions are affected by the new rules?
PI952, PI966, and previously recommended SoC limits now require mandatory compliance for certain battery types and packaging methods.
How can companies ensure compliance efficiently?
Partnering with experienced battery manufacturers like Redway Battery, which integrates shipping safety into production, ensures seamless compliance with minimal operational disruption.
