Lithium batteries have become an integral part of our everyday lives \u2013 whether in smartphones, laptops, or industrial applications. However, transporting them carries risks that can lead to mechanical damage, thermal stress, or short circuits, which can lead to overheating and, in extreme cases, thermal runaway. To mitigate these risks, the United Nations regulates the global transport of dangerous goods through the UN Manual of Tests and Criteria. For lithium batteries, the relevant section is UN 38.3, which sets strict safety standards that must be confirmed in the tests described therein.<\/p>\n\n\n\n

A significant change affecting air shipments will come into effect on January 1, 2026.<\/p>\n\n\n\n

Previous regulation<\/strong><\/h2>\n\n\n\n

The following has been in effect since April 1, 2016:<\/p>\n\n\n\n

\u2022 Lithium batteries shipped alone (UN 3480, PI 965) may only be transported by air freight with a maximum state of charge (SoC) of 30%.<\/p>\n\n\n\n

\u2022\u00a0For batteries installed in devices (PI 967) or packed with devices (PI 966), this 30% limit was previously only a recommendation, not a requirement.<\/p>\n\n\n\n

Background: Limiting the charge level reduces the risk of overheating and fire during flight.<\/p>\n\n\n\n

What will change from 2026?<\/strong><\/h2>\n\n\n\n

From January 1, 2026, the 30% rule will also apply to:<\/p>\n\n\n\n

\u2022 Batteries packaged together with devices (PI 966), – now mandatory.<\/p>\n\n\n\n

This means that in future, all lithium batteries \u2013 whether shipped alone or packed with devices \u2013 must be charged to a maximum of 30% before being transported by air. Only batteries already installed in the end device may continue to be shipped with a higher charge level.<\/p>\n\n\n\n

S\u00f6nke Zacher, Transport Expert at Jauch, on the new regulation<\/strong><\/h2>\n\n\n\n

Question: <\/strong>Mr. Zacher, why is this change so significant?<\/p>\n\n\n\n

S\u00f6nke Zacher:<\/strong> “The regulation makes air shipping more complex. Previously, the distinction between charge states was based on UN classification: UN3480 (cells or batteries alone) meant a maximum of 30% SoC, and UN3481 (packaged in or with devices) had no restriction. Now, UN3481 includes two different states of charge for air transport. In practice, this is unlikely to cause any major problems, as most major cell manufacturers already produce and ship with a maximum state of charge of 30%. Only where recharging takes place before packaging does the transport route need to be considered.”<\/p>\n\n\n\n

Question:<\/strong> What does this mean for companies?<\/p>\n\n\n\n

S\u00f6nke Zacher:<\/strong> “The rules are being reinforced, and everyone involved needs to take note of them. These regulations exist for good reason \u2013 to ensure safety.Unfortunately, there is still a lot of ignorance worldwide and, as a result, many transports are not carried out correctly. As long as nothing happens, it doesn’t stand out. But when incidents occur, it can be really expensive. I Therefore, I strongly recommend compliance with the regulations.”<\/p>\n\n\n\n
