Cleveland Cliffs, North America’s largest flat-rolled steel producer, has recently announced significant operational changes that will reshape parts of the American steel landscape. On May 2, 2025, the steelmaking giant revealed plans to indefinitely idle three steel plants across Pennsylvania and Illinois, affecting approximately 950 workers 1. This decision comes on the heels of earlier announcements to idle facilities in Michigan and Minnesota, creating a pattern that raises important questions about the current state of the domestic steel industry. As a major player in the US steel market and a primary supplier to the automotive sector, Cleveland Cliffs’ operational decisions serve as important indicators of broader market conditions, supply chain dynamics, and the effectiveness of trade policies designed to protect American steel producers.
Cleveland Cliffs’ Recent Plant Idling Announcement
Cleveland Cliffs has announced plans to indefinitely idle three steel plants starting around June 30, 2025. The affected facilities include two Pennsylvania plants-one in Steelton and another in Conshohocken-as well as a plant in Riverdale, Illinois1. This operational adjustment will impact approximately 950 workers across these three locations and comes after the required 60-day notice period mandated by federal law1. Each of these facilities specializes in products that Cleveland Cliffs has characterized as falling “outside of Cliffs’ core business focus,” including rail, specialty plate, and high-carbon sheet1
The Steelton facility, located near Harrisburg, Pennsylvania, primarily manufactures rails for the transportation industry1. The Conshohocken plant serves as a plate finishing facility near Philadelphia1. Meanwhile, the Riverdale facility outside of Chicago operates as a compact strip mill that produces high-carbon steel sheets1. What makes the Riverdale operation particularly notable is its unique supply chain arrangement-it sources hot metal from Cleveland Cliffs’ steel mill in East Chicago, Indiana, transporting the material across the state border into Illinois via specialized torpedo cars1.
While these three facilities face indefinite idling, Cleveland Cliffs has emphasized that its flat-rolled steel production levels will not be affected by these actions1. This suggests a strategic reallocation of resources rather than an overall reduction in the company’s total output capacity. The company has framed these moves as “temporary, indefinite idles” that are “a necessary response to insufficient demand and pricing for the products the affected facilities produce”1.
The Rationale Behind Cleveland Cliffs’ Decision
Cleveland Cliffs has explicitly stated that these plant idlings are driven by “insufficient demand and pricing” for the specific products manufactured at the affected facilities10. The company has been careful to point out that the decision is not related to President Trump’s tariffs on steel imports1. Instead, the focus appears to be on optimizing the company’s product portfolio and production footprint.
One key insight into Cleveland Cliffs’ strategy comes from their description of the affected products as falling “outside of Cliffs’ core business focus”1. This suggests a deliberate move toward concentrating operations on their primary product lines, particularly those serving the automotive industry, which has historically been a major customer for the company19. By idling facilities that produce rails, specialty plate, and high-carbon sheet, Cleveland Cliffs may be strategically repositioning itself to better align with market opportunities in its core business segments.
The timing and nature of these idlings raise questions about the age and efficiency of the affected facilities. While not explicitly stated in recent announcements, older steel plants typically face higher operational costs and maintenance challenges compared to newer, more technologically advanced facilities. The steel industry has been undergoing consolidation and modernization for decades, with companies often choosing to concentrate production in their most efficient operations. The affected plants may represent older or less efficient parts of Cleveland Cliffs’ production network that became economically challenging to maintain during periods of reduced demand or pricing pressure.
Market conditions in the steel industry have been complex in recent years, with fluctuating demand across different sectors. The company’s explicit mention of “insufficient demand and pricing” points to challenges in specific market segments rather than industry-wide issues1. This targeted approach to capacity adjustment suggests Cleveland Cliffs is responding to specific market signals rather than implementing across-the-board cutbacks.
Previous Capacity Adjustments by Cleveland Cliffs
The May 2025 announcement follows a pattern of strategic capacity adjustments that Cleveland Cliffs has implemented in recent months. In March 2025, the company announced plans to idle steelmaking operations at its Dearborn Works in Michigan, affecting approximately 600 workers1. Unlike the most recent idlings, which were attributed to product-specific market conditions, the Dearborn idling was explicitly linked to “weak automotive production in the United States”1.
The Dearborn facility, which is situated near Detroit’s automotive manufacturing hub, has been particularly vulnerable to fluctuations in automotive demand. The idling specifically targeted the blast furnace, basic oxygen furnace steel shop, and continuous casting facilities while keeping other operations running1. This selective approach allowed the company to maintain employment for approximately 550 workers at the site’s finishing facilities, including the pickling line tandem cold mill and the continuous galvanizing line16.
In addition to the steel plant adjustments, Cleveland Cliffs announced in March 2025 that it would idle or partially idle two iron ore mines in Minnesota-Minorca in Virginia and Hibbing in Minnesota-resulting in layoffs for approximately 630 workers1. This decision was attributed to “an accumulation of pig iron pellets in excess of expected needs”16, indicating challenges in balancing raw material production with downstream steel manufacturing requirements.
While idling several facilities, Cleveland Cliffs has simultaneously planned to resume operations at its Cleveland Works No. 6 blast furnace, which was idled in September 2024 due to declining demand for automotive steel16. The company indicated that this restart would help offset the Dearborn idling, though analysts noted that the shift represented a net reduction of about 600,000 tons per year of production capacity16.
This pattern of selective idling and restarting suggests a dynamic approach to capacity management, with Cleveland Cliffs adjusting individual facilities based on specific market conditions, product demand, and operational efficiencies rather than implementing uniform cutbacks across its network.
Impact on US Steel Industry Capacity Utilization
The idling of multiple Cleveland Cliffs facilities raises important questions about overall capacity utilization in the US steel industry. Capacity utilization-the percentage of available production capacity that is actually being used-serves as a key indicator of industry health and efficiency. Steel manufacturers typically aim for utilization rates of 80% or higher to achieve optimal operational economics.
Cleveland Cliffs’ recent idlings, while significant for the affected communities and workers, represent a strategic adjustment rather than a broad industry contraction. The company has emphasized that its flat-rolled steel production levels will not be affected by the most recent idlings10, suggesting a reallocation of production rather than an overall reduction in output. However, the earlier Dearborn idling, combined with the Cleveland Works restart, was expected to result in a net reduction of approximately 600,000 tons per year of production capacity16.
When steel producers idle capacity, the impact on overall industry utilization rates depends on several factors, including whether other producers increase their output to fill market gaps and whether demand shifts to alternative products or imports. Historically, capacity reductions have often led to improved utilization rates for remaining operations, potentially enhancing efficiency and profitability for producers that maintain full operations.
The selective nature of Cleveland Cliffs’ capacity adjustments-focusing on specific products “outside of Cliffs’ core business focus”1-suggests a targeted approach that may have limited impact on broader industry utilization rates. Products like rail, specialty plate, and high-carbon sheet represent specialized market segments that may not significantly affect utilization in major product categories like automotive sheet or construction products.
Effects on Steel Market Dynamics
Capacity adjustments like those announced by Cleveland Cliffs typically have cascading effects throughout steel markets, potentially influencing lead times, pricing dynamics, and supply chain relationships. The idling of specialized production facilities can create particular market impacts for the specific products manufactured at those sites.
Lead times-the duration between order placement and delivery-often extend when production capacity is reduced. For products manufactured at the idled facilities, including rail, specialty plate, and high-carbon sheet, customers may experience longer wait times if demand remains steady while available supply decreases. This effect may be particularly pronounced for specialized products with limited alternative sources of supply, such as the rails produced at the Steelton facility.
Pricing dynamics often respond directly to capacity adjustments. When capacity is reduced in a specific product category, prices typically increase if demand remains constant or grows. This relationship between supply and pricing appears to be at the heart of Cleveland Cliffs’ decision, as the company cited “insufficient demand and pricing” as the primary driver for the idlings10. The implication is that current market prices do not justify continued production of these specialized products, at least at the affected facilities.
Supply chain considerations extend beyond immediate customers to affect downstream manufacturers and distributors. For instance, the rail products from the Steelton facility support transportation infrastructure projects, while specialty plate and high-carbon sheet serve various industrial applications. Customers in these sectors may need to seek alternative suppliers, potentially leading to shifts in established supply chain relationships.
Historical examples of capacity adjustments in the steel industry have demonstrated these market effects. When steel producers have idled capacity in the past, remaining producers often gained pricing power and market share, particularly in specialized product categories with limited competition. However, these effects can be temporary, as market forces eventually establish new equilibrium conditions.
The Tariff Paradox: Why Idle Plants During Protective Measures?
One of the most intriguing aspects of Cleveland Cliffs’ recent capacity adjustments is their timing relative to steel tariff policies. Steel tariffs have been implemented to protect domestic producers from foreign competition, theoretically enabling American steelmakers to maintain higher capacity utilization and profitability. The apparent contradiction between protective trade measures and capacity reductions raises important questions about market dynamics and policy effectiveness.
Cleveland Cliffs has explicitly stated that its recent idling decisions are not related to President Trump’s tariffs10. Instead, the company has expressed optimism about the potential benefits of these policies, stating, “We believe that, once President Trump’s policies take full effect and automotive production is re-shored, we should be able to resume steel production at Dearborn”1. This statement suggests that Cleveland Cliffs views the current idlings as temporary adjustments while awaiting the full implementation and impact of trade policies.
The company’s chairman, president, and CEO, Lourenco Goncalves, has been “a vocal supporter of the Trump administration’s efforts to use tariffs in favor of U.S. steel production”14. Cleveland Cliffs’ corporate position emphasizes the importance of tariffs in protecting “the U.S. economy, national security, and industrial base from the adverse effects of global steel overproduction”19. Their public statements highlight concerns about “foreign producers, often backed by government subsidies,” flooding “international markets with artificially cheap steel, undercutting American manufacturers and threatening domestic jobs”19.
Despite this supportive stance on tariffs, Cleveland Cliffs is adjusting capacity in response to specific market conditions rather than waiting for tariff benefits to materialize fully. This approach suggests a pragmatic business strategy that balances long-term policy expectations with short-term market realities. While the company may anticipate future benefits from tariffs, particularly in core automotive markets, current conditions for specialized products appear to necessitate immediate adjustments.
Future Outlook for Cleveland Cliffs and the US Steel Industry
Cleveland Cliffs’ recent capacity adjustments offer insights into both the company’s strategic direction and broader industry trends. Despite the idlings, the company has framed these moves as “temporary” and maintained an optimistic outlook about potential restarts when market conditions improve10.
For the Dearborn facility specifically, Cleveland Cliffs has explicitly tied its potential restart to President Trump’s policies taking “full effect and automotive production is re-shored”10. This perspective aligns with the company’s public support for “Buy American” initiatives and domestic manufacturing19. Cleveland Cliffs has even implemented an employee incentive program to encourage the purchase of American-made products, particularly highlighting its alignment with President Trump’s “America-First” agenda19.
The planned restart of the Cleveland Works blast furnace demonstrates that idling decisions are indeed reversible when market conditions warrant. This facility, which was idled in September 2024 due to declining automotive steel demand, is now scheduled to resume operations16. Such dynamic capacity management suggests that Cleveland Cliffs views its production network as flexible, capable of adjusting to changing market conditions rather than permanent contraction.
Market projections for steel demand remain complex, with different sectors showing varying trends. While automotive production-a key market for Cleveland Cliffs-has experienced weakness, cited as the primary reason for the Dearborn idling14, other sectors may show different patterns. The company’s focus on its “core business” suggests a strategic prioritization of automotive and other flat-rolled steel applications where it perceives stronger long-term opportunities.
Long-term industry trends point toward continued consolidation, technological advancement, and specialization among steel producers. Cleveland Cliffs has positioned itself as North America’s largest flat-rolled steel producer and supplier of iron ore pellets19, indicating a strategic focus on scale and integration. The recent acquisition of Stelco Holdings Inc. further diversified the company away from the auto sector14, suggesting a recognition of the benefits of market diversification.
Conclusion
Cleveland Cliffs’ decision to idle three steel plants in Pennsylvania and Illinois represents a strategic response to specific market conditions rather than a fundamental shift in the company’s outlook or capabilities. By adjusting capacity for products “outside of Cliffs’ core business focus”1, the company appears to be optimizing its production footprint while maintaining its primary focus on automotive and other flat-rolled steel applications.
These capacity adjustments highlight the dynamic nature of the steel industry, where producers must continuously balance production capabilities with market demand and pricing realities. While protective trade measures like tariffs aim to strengthen the position of domestic steel producers, companies must still make pragmatic business decisions based on current market conditions while anticipating future policy impacts.
For workers, communities, and customers affected by these idlings, the designation of these moves as “temporary” offers some hope for eventual restarts. Cleveland Cliffs’ explicit linking of potential restarts to policy implementation and market improvements suggests that these facilities may resume operations under the right conditions.
The broader implications for the US steel industry include potential shifts in specialized product markets, possible pricing adjustments for affected products, and evolving supply chain relationships. As Cleveland Cliffs and other domestic producers navigate changing market conditions and policy environments, their capacity decisions will continue to shape the landscape of American steel production.
