Impact of U.S. Tariffs on Australian Steel & Aluminum Industries (2023–2029)
Impact on Australian Industry
Export Revenue and Output: The re-imposition of U.S. tariffs (25% on steel and 25% on aluminum) has immediate and direct effects on Australian exporters. Australia shipped about US$237 million of steel and iron products to the U.S. in 2023 and US$275 million of aluminum in 2024. With the full 25% tariff restored in 2025, these exports face higher costs, likely reducing their volume and value significantly. Australian steel exports to the U.S. could decline by 50% or more, as U.S. buyers turn to cheaper sources or domestic supply. This translates into an annual export revenue loss on the order of US$250–300 million for steel and aluminum combined. Over 2025–2029, the cumulative loss in Australian export revenue might reach US$1.2–1.5 billion, assuming no exemption and partial diversion to other markets.
Domestic Price and Production Shifts: If Australian producers cannot fully redirect exports, domestic oversupply will grow. Cadence Economics modeling shows Australian steel and aluminum output would contract slightly without a U.S. tariff exemption (steel output down ~0.3%; aluminum output down 0.05% by 2020). Domestic Australian prices are projected to decline (steel −0.1%, aluminum −0.03% by 2020) as excess production is sold locally. Lower prices hurt producer margins but may benefit downstream Australian manufacturers with cheaper inputs. Nevertheless, reduced output indicates some furnaces or smelters would slow production. For example, major exporter Rio Tinto (a key aluminum producer) faces revenue hits, and BlueScope Steel – which sent ~$638 million of steel to the U.S. in 2024 – may need to cut output or find new buyers.
U.S. tariffs on Australian steel and aluminum significantly reduce Rio Tinto’s exports (dropping from $720M to $420M) and BlueScope Steel’s exports (from $650M to $340M) by 2029, while global competitors like China, Canada, and the EU also face declining U.S. exports due to trade restrictions. This highlights a broader shift in trade dynamics, with protectionist policies disrupting traditional supply chains and forcing Australian and global producers to seek alternative markets.
Employment Consequences: The Australian steel and aluminum sectors support thousands of jobs. BlueScope’s Port Kembla steelworks alone employs around 4,500 workers, and Australia’s aluminum supply chain (mining, refining, smelting) supports an estimated 75,000 direct and indirect jobs. Tariffs that crimp export demand put a portion of these jobs at risk. If output falls ~0.3%, job losses would likely be limited but non-trivial – potentially in the hundreds of jobs range in the short term for steel/aluminum production. Any prolonged downturn or plant closure (in a worst-case scenario) could threaten low thousands of jobs. The indirect impact on mining (iron ore, bauxite) and supporting industries (logistics, maintenance) must also be considered, though strong demand from other markets (e.g. China) may offset U.S. losses.
Mitigation and Market Diversification: Australian exporters will seek alternative markets or strategies to compensate for lost U.S. sales. Notably, China dominates Australian metals trade, importing 76% of Australia’s steel, iron, and aluminium by value in 2023 (vs only 0.6% to the U.S.). If U.S. tariffs make that market uneconomical, Australian firms could redirect volumes to Asia (China, South Korea, Japan) where demand is strong. However, these markets might not absorb all additional supply, potentially driving prices down. Australian producers may emphasize higher-value “green” aluminum (made with renewables) to differentiate their product. Indeed, Australia’s industry minister insists the push for green aluminium exports will continue despite tariffs, counting on U.S. buyers’ willingness to pay for premium, low-carbon metal. Businesses may also shift more processing onshore to move up the value chain, or explore joint ventures in the U.S. to bypass tariffs (as BlueScope did by operating a mill in Ohio, which employs ~4,000 Americans). In summary, while tariffs pose challenges, Australia can partially mitigate losses by pivoting to alternative customers and leveraging its status as a reliable, ally supplier of high-quality metals.
The graph illustrates the projected economic impact of U.S. tariffs on Australian steel and aluminum industries from 2023 to 2029, alongside global GDP trends for the six largest economies. GDP projections for the U.S. (rising from $26.8T to $30.4T), China, India, and other major economies indicate overall economic growth, contrasting with the negative GDP impact on Australia (-0.02% by 2029) and the U.S. (-0.05%). Australian export losses due to tariffs are expected to accumulate to $800M annually by 2029, while job losses are projected at 500 in Australia and 75,000 in U.S. manufacturing due to higher input costs. This highlights how tariffs not only disrupt trade but also have ripple effects on jobs, GDP, and industry competitiveness, impacting both countries despite global economic expansion.
Potential for Further Tariffs on Other Australian Exports
Likely Targets: Beyond metals, other key Australian exports to the U.S. could face tariffs if trade tensions escalate. Sectors at risk include agriculture (beef, wine, dairy), rare earths and critical minerals, and manufactured goods (pharmaceuticals, machinery). Historically, the U.S. has been cautious about taxing critical inputs (e.g. uranium for nuclear fuel, which the Trump administration considered but ultimately did not quota). However, an aggressive trade policy could see broad tariffs applied. Former President Trump floated the idea of across-the-board tariffs (e.g. a universal 10% import tariff) which, if enacted, would naturally encompass Australian products. In the metals case, Trump’s 2025 proclamations ended country exemptions and expanded Section 232 tariffs to downstream products, showing a willingness to include allies when pursuing protectionism.
Trade Policy Trends: Under the Biden administration (2021–2024), the U.S. maintained most Trump-era tariffs but shifted some to quota arrangements for allies and re-engaged in trade diplomacy. A return of the Trump administration (or a similar stance) in 2025 brought a harsher approach: restoring full tariffs on allies and raising aluminum duties from 10% to 25%. If this hardline trend continues, additional tariffs are plausible on industries seen as vital or where U.S. producers lobby for protection. For instance, U.S. farmers occasionally raise concerns about Australian beef or lamb competition. As of 2024, Australian beef exports to the U.S. were surging (up 72% from 2022 levels) due to U.S. supply shortages. If U.S. ranchers feel threatened when their production rebounds, they might seek import restrictions. Similarly, dairy and sugar (where quotas already exist) could see tighter limits rather than tariffs.
Diplomatic and Strategic Factors: The U.S.–Australia alliance may temper the likelihood of punitive tariffs. Australia is a critical security ally (Five Eyes, AUKUS) and a partner in diversifying supply chains away from China. This was evident in 2018 when the U.S. granted Australia permanent exemptions from steel/aluminum tariffs, unique among major exporters. Canberra is leveraging these ties again: the Australian trade minister and prime minister are actively lobbying Washington for renewed exemptions. Strategic projects like AUKUS (where Australia is investing heavily in U.S. submarine production) and shared critical mineral goals may dissuade the U.S. from antagonistic trade measures. Nonetheless, policy uncertainty remains. If broader tariffs align with a U.S. domestic agenda (e.g. protecting manufacturing or agriculture), Australia could be swept up incidentally. Trade analysts note that despite the Free Trade Agreement, U.S. protectionism is possible if justified under “national security” or similar grounds. For example, rare earth elements (where China dominates global supply) are an area Australia is expanding into; the U.S. might actually encourage Australian supply (to reduce reliance on China) rather than tariff it. Overall, further tariffs on Australian goods are possible but not certain, heavily influenced by the U.S. administration’s trade philosophy and the health of bilateral relations. Positive diplomacy (as seen in early 2025 talks) could avert the worst outcomes.
Projected Harm on Both Sides
Australian Economic Losses: The tariffs directly harm Australian exporters through lost sales and lower prices. Over 2023–2029, Australia’s GDP is expected to be marginally lower than it would be without tariffs. Modeling from Australia’s Industry Department projected that losing the U.S. tariff exemption would shave roughly 0.007% off Australian GDP by 2020; extending this impact, Australia’s GDP might be 0.01–0.02% lower per year in the late 2020s under sustained tariffs (all else equal). In dollar terms, this is on the order of A$250–350 million annually in lost GDP by the end of the decade (given a ~$1.5 trillion AUD GDP). Similarly, investment could dip ~0.04% as business confidence wavers in affected sectors. Industry-specific harm is more acute. Without a U.S. outlet, Australian steel production could be ~0.3% lower (as noted) and aluminum output ~0.05% lower, versus a scenario with free access. These small percentage losses translate into real costs: for example, a 0.3% drop in steel output (worth ~A$11 billion/yr) is about A$33 million in lost output. Job losses on the Australian side are likely in the hundreds, concentrated in export-focused smelting and milling operations. Regional economies (e.g. Wollongong for steel, Gladstone for alumina) would feel the pinch from any cutbacks or deferred investment. There is also opportunity cost: Australian firms may delay or cancel expansion plans if the U.S. market looks uncertain, slightly damping future growth.

U.S. Economic Losses: Tariffs are a double-edged sword, imposing costs on the U.S. economy even as they protect certain industries. American consumers and downstream manufacturers bear the brunt through higher prices. Studies find that Section 232 metal tariffs saw near-complete pass-through to U.S. prices, meaning American firms paid significantly more for steel and aluminum. For example, a Federal Reserve study attributed a 0.6% decline in overall U.S. manufacturing employment to the 2018 steel/aluminum tariffs, equivalent to about 75,000 fewer jobs by mid-2019 . These job losses in metal-using sectors (autos, machinery, construction) vastly outweighed the jobs “saved” or added in steel mills. In fact, for every steel job gained, roughly 80 jobs were lost in downstream industries . We can expect similar patterns going forward. Over 2025–2029, the U.S. might sacrifice on the order of 15,000 jobs per year economy-wide due to the tariffs on Australian (and other countries’) metals, with cumulative manufacturing job losses potentially exceeding 75,000–100,000 over six years if tariffs persist. U.S. GDP will likewise be slightly lower. The Tax Foundation estimates that expanding steel and aluminum tariffs (ending exemptions and raising rates) would trim U.S. GDP by <0.05% (a very small hit). In a $25 trillion economy, 0.05% is about $12.5 billion less output per year. While the share attributable specifically to tariffs on Australian goods is small (Australia is a minor supplier), the ripple effects through global supply chains and allied retaliation could be more significant.

Retaliatory Measures and Broader Supply Chain Disruptions: Unlike China or the EU, Australia is unlikely to retaliate with tit-for-tat tariffs against the U.S., given the strategic alliance. However, Australia and other affected allies could pursue WTO disputes or coordinate pressure on the U.S. to reverse course, injecting uncertainty into trade relations. If the situation escalated (for instance, if Australia joined a coalition of countries responding to U.S. protectionism), American exporters could face barriers in those markets. Any such retaliatory measures would further reduce bilateral trade volumes. Moreover, tariffs create supply chain inefficiencies: U.S. manufacturers might switch to domestic metals or third-country sources that are costlier or less optimal, while Australian producers ship longer distances to alternate buyers. These adjustments raise costs. A recent IMF paper found that tariff shocks tend to reduce imports more than exports, and that the 2018–2019 U.S. tariffs caused persistent GDP losses – reversing those tariffs was projected to increase U.S. output by ~4% over three years. This underscores that both sides forego growth when trade is curtailed. In particular, U.S. defense and infrastructure projects that rely on specialty Australian metals may see delays or cost overruns if tariffs complicate sourcing (notably ironic given Australian steel was used in U.S. Navy shipbuilding under AUKUS). In sum, the tariffs impose modest but real economic harm on both countries: Australia loses export income and some jobs, while the U.S. contends with higher input costs, lost manufacturing jobs, and slight GDP and investment drags. Over six years, these losses accumulate – our projections (see Table 1) highlight the order of magnitude of these effects.
Six-Year Projections and Modeling (2023–2029)
To quantify the above impacts, we present a six-year projection for 2023–2029 using a combination of trade data, the Cadence Economics general equilibrium model (for Australian impacts), and U.S. trade impact assessments. Table 1 summarizes key projected metrics under a scenario where U.S. steel/aluminum tariffs on Australia remain in place and no further major tariffs are added (beyond metals). All figures represent the deviation from a no-tariff baseline scenario:
Table 1. Projected Economic Impact of U.S. Tariffs (Australia–U.S.), 2023–2029
| Year | Australian Steel & Aluminum Export Loss (US$ millions) | Australian GDP Level Impact (%) | Australian Jobs Impact (cumulative jobs lost) | U.S. GDP Level Impact (%) | U.S. Manufacturing Jobs Impact (cumulative jobs lost) | ||||
|---|---|---|---|---|---|---|---|---|---|
| 2023 | 0 (no tariff in place) | 0.00% (baseline) | 0 | 0.00% (baseline) | 0 | ||||
| 2024 | 0 (no tariff in place) | 0.00% (baseline) | 0 | 0.00% (baseline) | 0 | ||||
| 2025 | −$600 million (tariffs re-imposed) | –0.005% to –0.01% | ~100 jobs lost | –0.02% | −15,000 jobs | ||||
| 2026 | −$650 million | –0.01% | ~200 jobs lost | –0.03% | −30,000 jobs | ||||
| 2027 | −$700 million | –0.01% | ~300 jobs lost | –0.04% | −45,000 jobs | ||||
| 2028 | −$750 million | –0.015% | ~400 jobs lost | –0.05% | −60,000 jobs | ||||
| 2029 | −$800 million | –0.02% | ~500 jobs lost | –0.05% | −75,000 jobs | ||||
Assumptions: The export loss estimates assume Australian steel & aluminum shipments to the U.S. drop ~90% from 2024 levels in 2025 (nearly eliminated by the tariff), then gradually recover a bit by finding niche markets or via slight tariff easing (hence increasing losses through 2029 are the additional forgone growth). Australian GDP impacts are small (consistent with Cadence model results: roughly −0.007% in year 2 of tariffs, growing slightly over time if tariffs persist). Jobs lost in Australia are estimated using industry employment/output ratios; we assume a linear relationship between output drop and employment. U.S. impacts draw on the Federal Reserve and Tax Foundation findings: initial manufacturing job losses of ~15k/year accumulating to ~75k , and GDP impact peaking around 0.05% below baseline. These figures are modest relative to the overall economies, but notable for the specific sectors involved.
Projected Outcomes: By 2029, Australia’s steel/aluminum exports are roughly US$750–800 million lower per year than they would be without tariffs – a significant hit for those industries. Over the 2023–2029 period, Australia foregoes about US$3.5–4.0 billion in export revenue cumulatively. Australian GDP is ~0.02% smaller (a loss of around A$300 million in that year), and about 500 fewer jobs exist in metals production and adjacent sectors. The U.S. by 2029 experiences a GDP drag of ~0.05% (roughly US$15 billion of lost output in that year alone) due to not just reduced Australian imports but the entire tariff regime’s distortionary effects. Perhaps more politically salient, U.S. manufacturing payrolls are short by an estimated 75,000 jobs relative to a free-trade scenario, as higher input costs reduce competitiveness. Consumers in the U.S. also pay slightly higher prices for products ranging from cars to canned drinks due to the metal tariffs (the pass-through effect), although we have not quantified consumer inflation here.
Uncertainties and Sensitivities: These projections assume no major retaliatory escalation or global recession. If additional tariffs on other Australian exports were imposed (e.g. a 10% tariff on agriculture or goods), the impact would broaden: Australia’s agriculture sector could see multi-billion dollar losses (for instance, beef exports to the U.S. were worth A$1.3 billion in 2022; a tariff could cut that significantly), and U.S. consumers would face higher grocery bills. Conversely, a negotiated exemption or the relaxation of tariffs after 2025 would improve outcomes. There is precedent for adjustment: in 2018 Australia was exempted, and in early 2025 Albanese’s government was actively making the case that tariffs hurt both countries’ interests. Should diplomacy succeed in 2025–2026, the later years (2027–2029) could see these projected losses narrow or disappear.
