Li-S Energy Wins US Airfreight Approval to Ship Cells Into Defence Market

By Josua Ferreira -

Regulatory green light opens the door to US defence customers

Li-S Energy (ASX: LIS) has secured dual regulatory approvals to airfreight its prototype lithium-sulfur cells from Australia to the United States, opening a direct supply pathway into the world’s largest defence market. The approvals, granted by Australia’s Civil Aviation Safety Authority (CASA) and the US Pipeline and Hazardous Materials Safety Administration (PHMSA), working in coordination with the US Federal Aviation Administration (FAA), are described by the company as a prerequisite to acquiring significant supply agreements and revenue.

The milestone caps over 18 months of focused effort by the LIS technical and compliance teams navigating complex multi-national regulatory requirements. Key highlights from the announcement include:

  • Air transport approvals secured in both Australia and the USA for lithium-sulfur cell shipments.
  • Approvals open a direct pathway into the world’s largest defence market.
  • The outcome reinforces LIS’s role in sovereign and allied supply chains, building on the company’s AUKUS membership and Paladin Defence Services US representation.
  • UN38.3 certification is underway to enable larger-volume shipments under standard classifications.

Why this approval is harder to get than it sounds

Lithium-sulfur isn’t treated like standard lithium-ion

Li-S Energy’s cells are not a conventional battery chemistry. As an ultra-high energy density prototype, they require dangerous goods approvals that go beyond the classifications applied to standard lithium-ion cells.

The authorising framework here is ICAO/IATA Special Provision A88, the international standard specifically designed for transporting prototype lithium cells by air. This is not an off-the-shelf process; it is a bespoke regulatory pathway reserved for novel chemistries that do not yet fit standard dangerous goods categories.

For investors, that distinction matters. Clearing this regulatory hurdle signals that LIS’s cell design has reached a level of technical maturity sufficient to satisfy both Australian and US safety authorities. It also means the company can now physically deliver cells to US customers for the first time, converting years of technology development into tangible commercial activity.

A credible seat at the allied defence table

US market access backed by AUKUS and Paladin Defence

The United States represents the largest and most sophisticated defence market globally, with rapid proliferation of unmanned aerial, ground, and autonomous platforms generating substantial demand for advanced batteries that perform beyond conventional lithium-ion capabilities.

The shipment approvals do not stand alone. They complement two existing strategic enablers that LIS has already established: its AUKUS membership, which permits cell exports to the US and UK without requiring individual export permits, and the appointment of Paladin Defence Services as the company’s US Representative, providing direct engagement with US defence primes and government agencies.

Together, these three capabilities position LIS as a credible Australian contributor to the sovereign and allied supply chains for advanced energy storage that allied defence forces are actively building.

Dr Lee Finniear, CEO and Managing Director

“These approvals give Li-S Energy a working pathway to deliver cells from our Geelong production line directly to US customers, primes and Government agencies evaluating next-generation drone and defence platforms. Combined with our AUKUS membership and Paladin US representation, we now have the operational means to materially expand our US commercial pipeline.”

Dr Steve Rowlands, Chief Technology Officer

“These approvals reflect the maturity of our cell design and the controls around our innovative chemistry. We can now place working cells with US defence and drone integrators designing the next generation of unmanned platforms, where lithium-sulfur’s energy and weight advantages translate most directly into advanced capability.”

The table below summarises the four strategic enablers now in place for LIS’s US market entry:

Enabler What it is What it unlocks Status
CASA/PHMSA approvals Air transport clearance under ICAO/IATA Special Provision A88 Prototype cell shipments from Australia to US customers Secured – May 2026
AUKUS membership Allied defence export framework Cell exports to US and UK without individual export permits Active
Paladin Defence Services LIS’s appointed US Representative Direct engagement with US defence primes and government agencies Active
UN38.3 certification Standard dangerous goods cell classification Larger-volume shipments under standard classifications In progress

What comes next for LIS investors

With the Li-S Energy USA shipment approvals now secured, the company’s technology story is entering a commercial execution phase. LIS will begin dispatching prototype cells to US-based partners and customers on a project-by-project basis, enabling evaluation and integration trials with defence prime contractors, drone manufacturers, and government agencies.

The two-stage roadmap from here is:

  1. Commence prototype cell dispatches to US partners and customers (immediate).
  2. Complete UN38.3 certification to unlock standard-classification, larger-volume shipments (in progress).

Once UN38.3 certification is achieved, the company will be able to move beyond the Special Provision A88 pathway and ship cells at greater scale under standard dangerous goods classifications. That transition would represent a further step change in LIS’s ability to service US demand, and the company has indicated that work is already progressing.

Frequently Asked Questions

What are the Li-S Energy USA shipment approvals and why do they matter?

Li-S Energy has received regulatory clearance from Australia's CASA and the US PHMSA to airfreight its prototype lithium-sulfur cells between the two countries under ICAO/IATA Special Provision A88, a bespoke pathway for novel battery chemistries. This is significant because it allows LIS to physically deliver cells to US defence customers for the first time, converting years of technology development into tangible commercial activity.

What is ICAO/IATA Special Provision A88 and why does LIS need it?

Special Provision A88 is the international standard specifically designed for transporting prototype lithium cells by air that do not yet fit standard dangerous goods categories. Li-S Energy requires this pathway because its lithium-sulfur cells are a novel, ultra-high energy density chemistry that goes beyond the classifications applied to conventional lithium-ion batteries.

How does AUKUS membership benefit Li-S Energy's US market entry?

AUKUS membership allows Li-S Energy to export its cells to the US and UK without requiring individual export permits on each shipment, materially reducing administrative hurdles and enabling faster engagement with allied defence customers.

What is UN38.3 certification and what will it unlock for LIS?

UN38.3 is the standard dangerous goods classification for lithium cells that enables larger-volume shipments under conventional logistics frameworks rather than the bespoke Special Provision A88 pathway currently in use. Once LIS completes this certification, which is already in progress, it will be able to ship cells at greater scale to US customers.

What are the next commercial steps for Li-S Energy following the shipment approvals?

Li-S Energy plans to immediately begin dispatching prototype cells to US-based defence prime contractors, drone manufacturers, and government agencies for evaluation and integration trials, while simultaneously progressing UN38.3 certification to unlock standard-classification, larger-volume shipments.
