As of January 1, 2025, the IATA’s 66th Dangerous Goods Regulations (DGR) recommends that lithium-ion batteries—whether packed with equipment (UN 3481) or contained in equipment—be shipped with a state of charge (SoC) not exceeding 30% of their rated capacity. This aligns them with the longstanding rule for loose batteries (UN 3480)

What's Changing—and What's Mandatory

• Recommended in 2025:

  • Lithium-ion batteries packed with or contained in equipment should have SoC ≤ 30%

• Mandatory from Jan 1, 2026:

  • Batteries packed with equipment (UN 3481, PI 966) with a watt-hour rating > 2.7 Wh must comply with SoC ≤ 30%, or ship only with special authority approval.

  • Vehicles powered by lithium-ion batteries (UN 3556) with watt-hour > 100 Wh also move to mandatory SoC ≤ 30%, unless approved

Why It Matters

Lowering the SoC significantly reduces the risk of thermal runaway, a serious hazard during air transport. The 2025 recommendation period allows companies time to adapt processes and supply chains ahead of the mandatory requirements in 2026.
