Australia critical minerals 2026: lithium, rare earths, and the IRA-aligned offtake

The Australian upstream in a fractured market #

Australia produced roughly 86,000 tonnes of lithium content in 2025, more than half of global mined supply, even as the spodumene benchmark fell from its 2023 peak of about 8,000 US dollars per tonne to a corridor between 850 and 1,100 US dollars across the back half of 2025. Greenbushes, jointly held by IGO, Tianqi, and Albemarle, remained the lowest cost hard rock operation on the cost curve, while Pilbara Minerals' Pilgangoora expansion lifted nameplate capacity above one million tonnes of spodumene concentrate. Mt Marion, Wodgina, and Kathleen Valley filled out a producing set that gave Western Australia a structural advantage other jurisdictions cannot replicate this decade.

The picture in rare earths, nickel, and copper is more uneven. Lynas continued to operate the only commercial scale separated rare earth supply outside China, with Mt Weld feeding Kalgoorlie cracking and leaching and Malaysian separation, plus the Kalgoorlie heavy rare earth circuit ramping in 2026. Nickel told the harder story: Indonesian high pressure acid leach drove Australian sulfide producers offline through 2024 and into 2025, with BHP suspending Nickel West and several West Australian mines placed on care and maintenance. Copper sits in the middle, with BHP Olympic Dam, Glencore Mount Isa restart questions, and the Oak Dam discovery shaping a slower but more durable expansion path.

IRA Section 30D and the friend-shoring perimeter #

Section 30D of the US Internal Revenue Code, as amended by the Inflation Reduction Act and clarified through 2024 and 2025 Treasury guidance, conditions the 7,500 US dollar new clean vehicle credit on critical mineral and battery component sourcing tests, with a Foreign Entity of Concern exclusion that bars material assistance from Chinese, Russian, Iranian, and North Korean controlled entities. Australia qualifies as a country with which the United States has a free trade agreement for purposes of the critical minerals test, which means Australian extracted or processed lithium, nickel, cobalt, manganese, and graphite can count toward the 50 percent threshold that escalates to 80 percent in 2027.

The operational question is not whether Australian rocks are eligible. It is whether the corporate, financing, and offtake structure around those rocks survives the FEOC test. Treasury's 25 percent ownership and board influence thresholds, the licensing carve outs added in late 2024, and the transition rules for traceable battery materials together created a compliance map that trade analytics teams now have to maintain at the mine, refinery, and cathode precursor level. Greenbushes, with Tianqi holding an indirect stake through the Tianqi Lithium Energy Australia joint venture, is the canonical stress test.

Critical Minerals Facility and Future Made in Australia #

The Critical Minerals Facility, administered through Export Finance Australia, expanded to a 4 billion Australian dollar envelope under the 2024 settings and was effectively doubled in capital intensity by the Future Made in Australia package that the Albanese government legislated in late 2024. Production tax credits of 10 percent on the value of refined critical minerals, available from 2027 to 2040 on processing inside Australia, changed the build versus ship calculus for projects like Iluka's Eneabba refinery, Arafura's Nolans, and Australian Strategic Materials' Dubbo project.

The combined effect through 2026 is a policy stack that subsidizes downstream processing, underwrites offtake to allied buyers, and uses the National Reconstruction Fund to plug equity gaps that private markets will not bridge at current prices. For trade analytics teams, the relevant signal is not the headline dollar figure. It is the tightening alignment between Export Finance Australia conditionality, US Department of Energy Loan Programs Office co financing, and Department of Defense Industrial Base Analysis and Sustainment grants. Projects that show up on more than one of those balance sheets are the ones that will move.

Chinese ownership and offtake friction #

Chinese strategic investment in Australian critical minerals is concentrated, visible, and contested. Tianqi holds 51 percent of Tianqi Lithium Energy Australia, which in turn owns 51 percent of the Greenbushes operating entity, with IGO holding the remaining stakes and Albemarle holding a direct 49 percent of the mine. Yansteel, Shanghai Pengxin, and several Hong Kong listed vehicles hold positions across nickel, lithium, and rare earth juniors. The Foreign Investment Review Board blocked or restructured at least five proposed Chinese transactions across 2023 to 2025, including the forced divestment of stakes in Northern Minerals.

Offtake is where the friction translates into trade flow. Chinese converters still take the majority of Australian spodumene because they pay on time, accept variable grades, and pre finance shipments. US and Korean cathode makers want the same units but cannot match the working capital terms without IRA pass through. The result through 2025 was a bifurcated book at every major mine, with long term contracts to LG, Posco, and Tesla running parallel to spot tonnage that still flows to Ganfeng and Yahua. Section 30D compliance is forcing those books apart, but the transition is messy and the audit trail is what trade clients are paying for.

Three scenarios for 2026 to 2028 #

Our base case, assigned roughly 55 percent probability, has spodumene averaging 1,150 US dollars per tonne through 2026 and recovering toward 1,600 by 2028 as Chinese lepidolite supply discipline holds and US and European cell capacity additions absorb incremental Australian units. In this path Lynas commissions Kalgoorlie heavy rare earths on schedule, Iluka Eneabba starts in late 2026, and at least two new IRA aligned offtake structures replace Chinese tolling at midstream stage.

The bear case, at 25 percent probability, has Indonesian nickel and Chinese lepidolite continuing to flood the market, spodumene staying below 900 US dollars, and a wave of West Australian project deferrals through 2027 that hollows out the pipeline regardless of Future Made in Australia subsidies. The bull case, at 20 percent probability, has a 2027 enforcement tightening of FEOC rules, a Trump or successor administration applying Section 232 tariffs to Chinese refined battery materials, and Australian processed product commanding a 15 to 25 percent premium that finally clears project finance for Arafura, ASM, and the heavy rare earth circuit.

What trade and tariff teams should be modeling now #

The analytical surface for clients shifted in three concrete ways across 2025. First, the unit of analysis is no longer the country pair. It is the mine, refinery, and cell maker triple, with FEOC ownership tracing required at each node. Second, the relevant tariff stack is no longer just Section 301 and Section 232. It is the interaction of those duties with 30D credit value, FEOC disqualification, and the Australian production tax credit, which together determine whether a tonne of lithium hydroxide clears margin in Korea, Texas, or Kwinana. Third, the data refresh cadence that trade teams accepted in 2022, monthly customs prints with quarterly reconciliation, is no longer adequate to manage portfolio exposure to enforcement actions that move on a two to four week cycle.

Practical priorities for the next two quarters include rebuilding bill of materials traceability for any program that touches Section 30D, instrumenting offtake contract review against the Treasury 2024 transition rules, and stress testing nickel and rare earth exposure against a possible 2027 FEOC tightening. Clients that wait for the rule to land will find that the qualified supply has already been contracted by competitors who modeled it earlier.

How Deluair anchors the work: TradeWeave and Promethean #

TradeWeave is our trade analytics platform that ingests customs filings, bill of lading data, and corporate ownership graphs to produce FEOC adjusted exposure maps at the HS 8 digit level. For Australian critical minerals clients we operate a dedicated module that tracks 41 mines, 17 refineries, and the offtake counterparties for each, refreshed weekly against ABS, US Census, and Korean Customs releases. The platform flags ownership changes within 72 hours and produces auditable Section 30D eligibility memos that have been used in three Treasury comment submissions to date.

Promethean is our scenario and policy simulation engine, built around a calibrated model of US, Australian, EU, and Chinese trade policy responses. It runs the three scenarios above, and roughly 40 client specific variants, against project economics, contract pricing, and tariff stacks to produce decision ready outputs. Together TradeWeave and Promethean let trade and tariff teams move from descriptive reporting to prescriptive positioning, which is the level of insight that Australian critical minerals exposure now requires. Engagements typically run six to twelve weeks for a first deployment, with quarterly retainers thereafter.
