Lithium Battery Shipping Rules Changed in 2026. Here's Why Your Packaging Partner Should Know.

Lithium-ion batteries power everything from consumer electronics and medical devices to industrial equipment, electric vehicles, and energy-storage systems. As their use grows, so does the attention being paid to how these batteries are packaged, handled, and transported.

In 2026, an important air-shipping requirement changed.

Effective January 1, 2026, lithium-ion cells and batteries packed with equipment and shipped by air generally must be offered for transport at a state of charge no greater than 30% of their rated capacity. The requirement appears in IATA's 2026 Battery Shipping Regulations and applies to shipments governed by Packing Instruction 966, with specific provisions for shipments that require approval above that threshold.

Thirty percent may sound like a small technical detail.

But it illustrates something much bigger about packaging regulated products: selecting the right container is only one part of getting a product safely and compliantly through the supply chain.

What Changed for Lithium-Ion Batteries in 2026?

Lithium batteries have long been treated as dangerous goods in air transportation because of the risks associated with stored energy, flammable electrolytes, short circuits, fire, and thermal runaway.

IATA's 2026 guidance expands the use of reduced state-of-charge requirements.

For lithium-ion cells and batteries packed with equipment under Packing Instruction 966, Section I shipments must now generally be offered at no more than 30% of rated capacity. Cells or batteries above that level require approval from the State of Origin and State of the Operator under established conditions.

For certain Section II shipments, lithium-ion cells and batteries with a Watt-hour rating above 2.7 Wh are also subject to the 30% state-of-charge limit.

There is an important distinction, however. Lithium-ion batteries contained in equipment fall under a different packing instruction. For those shipments, IATA currently recommends, rather than universally mandates, offering batteries at no more than 30% rated capacity or 25% indicated battery capacity as an additional safety measure.

That distinction alone demonstrates why battery shipping requirements cannot be reduced to one simple rule.

How the battery is configured and shipped matters.

Why the 30% Rule Matters

Reducing a lithium-ion battery's state of charge helps reduce the energy available if something goes wrong during transportation.

IATA's 2026 guidance notes that cells and batteries shipped at a reduced state of charge are less prone to thermal runaway.

The aviation industry has paid particular attention to battery transportation because a battery fire can present serious challenges aboard an aircraft. U.S. transportation regulators have also previously introduced restrictions including prohibiting lithium-ion batteries shipped alone as cargo aboard passenger aircraft and limiting those batteries to 30% state of charge when transported on cargo aircraft.

The 2026 change extends that safety-focused approach to additional shipment configurations.

But the state of charge is only one part of the compliance picture.

Lithium Battery Compliance Goes Beyond the Package

When a company prepares a lithium battery product for shipment, the first question may seem simple:

What packaging do we need?

In reality, several factors can influence the answer.

• Product classification. Battery chemistry, Watt-hour rating, configuration, and intended shipment method can determine which dangerous-goods requirements apply.
• Packaging performance. Depending on the shipment, packaging may need to meet specific design, construction, or testing requirements.
• Protection and containment. Batteries may require inner packaging, cushioning, separation, protection from movement, or safeguards against short circuits and damage.
• Marking and labeling. Packages may need specific marks and labels based on battery classification and shipment configuration.
• Documentation. Certain dangerous-goods shipments require declarations, shipping information, or other supporting documentation.
• Transportation mode. Air, highway, rail, and maritime transportation can involve different regulatory frameworks and requirements.
• Carrier requirements. Individual carriers may impose additional restrictions or operational requirements beyond baseline regulations.

IATA itself notes that packaging batteries for freight is not a one-size-fits-all question. Battery type, quantity, packaging quality, and the package's ability to meet applicable performance requirements can all matter.

This is why packaging selection should not happen in isolation from the environment in which the package will actually travel.

Why Staying Current Matters

Regulations surrounding dangerous goods continue to evolve as battery technologies, transportation practices, and safety standards change.

IATA's 2026 Battery Shipping Regulations did more than adjust state-of-charge requirements. The edition also introduced updated battery classification guidance, additional packaging, marking, labeling and documentation examples, and a compliance checklist intended to help shippers evaluate battery shipments before offering them for air transportation.

For manufacturers and shippers, this means packaging specifications should be reviewed as products, transportation methods, and regulations evolve.

A package that was appropriate several years ago should not automatically be assumed to be appropriate today simply because the product still fits inside it.

What to Look for in a Packaging Partner

A packaging supplier can sell you a box, drum, container, closure, cushioning material, or other component.

A packaging partner should bring a broader understanding to the conversation.

For regulated products, that means considering questions like:

• What is going inside the package?
• How will it be handled?
• Where is it going?
• How is it getting there?
• What regulatory or performance requirements could affect the packaging decision?
• And what has changed since the last time the product was shipped?

Novvia Group's battery and electronics packaging capabilities include chemical-resistant bottles and jugs, industrial drums and large containers, closures and accessories, and UN-certified hazardous-material packaging designed for applications involving batteries, battery chemicals, and regulated electronics materials.

Across the broader Novvia Group portfolio, specialized companies also bring experience in hazardous-material packaging, UN certification, dangerous-goods solutions, testing, and regulated packaging applications.

The value of that expertise is not simply having access to another packaging format. It is being able to approach the package in the context of the product, transportation requirements, and supply chain around it.

The Bigger Picture

The 2026 state-of-charge requirement is one example of how quickly the regulatory environment surrounding lithium batteries can evolve.

For manufacturers and shippers, the takeaway is simple: packaging decisions should account for more than the container itself.

Novvia Group brings packaging expertise together with an understanding of the applications, transportation requirements, and regulatory considerations surrounding the products customers need to move safely through the supply chain.

Because with regulated products, safe packaging is part of the solution. Understanding the environment around it matters, too.
