Sager Electronics’ supplier marketing & product manager, Megan Burnside, explains what buyers need to know regarding the IATA’s new battery shipping regulations.
The latest updates from the International Air Transport Association (IATA) will significantly affect how lithium-ion and sodium-ion batteries are transported by air. Effective 1 January 2026, these changes introduce: new restrictions on the State of Charge (SoC) for lithium-ion batteries; establish regulations for sodium-ion batteries; and update labeling requirements. Understanding these changes is crucial for maintaining compliant supply chains.
SoC refers to the amount of energy a battery holds, expressed as a percentage of its total capacity. IATA’s new regulations mandate that stand-alone lithium-ion batteries shipped by air must have a SoC of no more than 30 per cent. This measure aims to mitigate the risk of overheating and fire during transport, as higher charge levels increase the likelihood of thermal runaway.
Sodium-ion batteries are emerging as a viable alternative to lithium-ion. IATA has introduced specific classifications for sodium-ion batteries, including dedicated UN numbers and shipping instructions like those for lithium-ion.
A key takeaway for buyers is that sodium-ion batteries are now subject to air transport regulations, including specific labeling and packaging requirements. As more manufacturers adopt sodium-ion technology, particularly for stationary energy storage and cost-sensitive applications, buyers must understand these regulations to inform their sourcing decisions.
IATA is also streamlining labeling by renaming the ‘Lithium Battery Mark’ to the ‘Battery Mark’ to encompass both lithium-ion and sodium-ion batteries. While the label’s design remains largely the same, shipments must now clearly display the correct UN number(s) for the batteries being transported.
Furthermore, IATA has updated classifications for battery-powered vehicles and devices, including those with built-in tracking technology. Buyers sourcing such equipment must ensure their suppliers comply with these updated guidelines.
Proactive planning is essential for mitigating potential supply chain disruptions. Buyers should collaborate with authorized distributors and their suppliers. Distributors specializing in power products possess the expertise to navigate these evolving regulations and ensure batteries are sourced from reputable, IATA-compliant manufacturers.
Buyers should also anticipate logistical adjustments due to the 30 per cent SoC limit. Additional charging time will be necessary if batteries need to be used immediately upon arrival. This is especially critical for industries that rely on backup power systems, medical devices and other applications where immediate battery readiness is paramount.
Ensuring all incoming shipments are correctly labeled with the new Battery Mark and corresponding UN numbers is also essential. While suppliers will transition to the new labels, early compliance verification can prevent delays during customs or transport.
Finally, buyers must stay informed about regulatory changes beyond IATA. Battery shipping regulations are subject to ongoing evolution, driven by technological advancements and safety considerations. Engaging with distribution partners and participating in industry discussions will help businesses stay ahead of these changes.
The new IATA regulations enhance safety in air transport but introduce new considerations for buyers. Understanding the SoC restrictions, sodium-ion battery classifications and labeling updates is crucial for maintaining compliance and minimizing supply chain disruptions. By working closely with a qualified distributor and leading battery manufacturers, buyers can confidently adapt to these changes and ensure the seamless flow of battery shipments in an increasingly regulated environment.
