Global Steel Output Declines in September While US Mills Post Year-on-Year Gain
24 October 2025
According to newly released figures from the World Steel Association compiled for September 2025, the global steel industry has faced another month of contraction, with steel output receding by approximately 3.5 million metric tons compared to August 2025 and by 1.6% relative to September 2024. This marks a continuing trend in production challenges worldwide for steel producers, driven by shifting economic demands, capacity constraints, and competitive pressures among leading steelmaking nations.
In the United States, however, there is a noteworthy divergence from this worldwide retreat. U.S. mills produced 6.9 million metric tons during September 2025, representing a robust 6.7% increase in output compared with the same period last year. While this is a significant year-on-year improvement, it still marks a 4.1% decline when compared with the previous month. The increase in American steel production year-to-date stands at 2.1%, helping the United States position itself among the few top-producing countries that have managed to outperform last year's volumes at the three-quarter mark.
Production dynamics continue to be shaped by supply-demand imbalances. In the U.S., greater production volumes have not yet translated into rising steel and iron scrap prices; instead, mills are paying flat or even declining prices in recent months. Data from the Raw Material Data Aggregation Service (RMDAS) shows that volatility in material pricing persists, contributing to uncertainty for recyclers, scrap suppliers, mill operators, and equipment vendors targeting the American steel sector. These trends are crucial for businesses relying on raw material procurement, long-term contract negotiations, and those seeking to navigate the evolving landscape of input costs.
Turkey and India, both major export destinations for U.S. steel recyclers, have experienced notable reductions in steel output compared to August, with Indian mills output contracting by 3.5% and Turkish output by 5.9% month-on-month. This has knock-on effects for American companies involved in export markets for ferrous scrap and steel products. Meanwhile, German steel production saw the largest percentage drop among major producers, signaling further instability in global supply chains and competitive dynamics for integrators and engineering firms active in cross-border steel projects.
Despite this mixed landscape, American mills have shown resilience and capacity for growth relative to key global peers. For mill operators and electricity/automation technology firms, this growth trajectory signals the need for ongoing investment in modernization, process optimization, and environmental compliance. As producers respond to both macroeconomic headwinds and persistent year-to-date softness in global output, U.S. steelmakers are poised to adjust their strategies on capex, upgrade initiatives, and supply chain risk management across forming, finishing, secondary metallurgy, and rolling operations.
Year-to-date, only three out of the ten largest steel-producing nations—India, the United States, and Turkey—have managed to outpace their 2024 output levels as of the end of September. Nevertheless, Chinese output remains the dominant factor globally, with its mills making up nearly 52% of total world production and showing notable month-on-month and year-on-year contraction. For American equipment providers, control system integrators, and technology vendors, the evolving constellation of production numbers and input prices will inform their strategic planning and deployment of advanced solutions for automation, measurement, and process efficiency, particularly as market sentiment turns toward supply-side challenges, demand uncertainties, and environmental sustainability priorities in the steel sector.
Looking ahead, all eyes in the U.S. steel business community remain focused on how these production trends will influence procurement, pricing, and international competitiveness. The capacity for American mills to maintain year-on-year gains amid global softness will shape planning for capital projects, plant installations, technology upgrades, and partnership investments in the months to come.
