ArcelorMittal Shutdown Impacts European Steel Supply: Satellite Data Signals Market Shift

ArcelorMittal Eisenhüttenstadt’s temporary production halt in Germany, due to scheduled maintenance, impacts the European steel market. According to news articles “ArcelorMittal Eisenhüttenstadt to suspend blast furnace operation“, “ArcelorMittal in Eisenhuttenstadt will carry out annual scheduled maintenance work at mine 5A“, “ArcelorMittal Eisenhüttenstadt to implement annual scheduled repair work at BF 5A“, and “ArcelorMittal temporarily stops melting“, blast furnace 5A will be offline from June 22nd to June 27-28th, 2025. We could not establish a direct relationship between these news and satellite-observed changes in activity because the satellite data contains only monthly aggregations until the end of June 2025.

Bar chart and satellite map of steel production activity in Europe

The mean steel plant activity in Europe fluctuates significantly between December 2024 and June 2025, with a notable rise and fall but the high values should be interpreted as erroneous outliers. Donetsksteel Metallurgical Plant shows a relatively stable activity level, ranging from 17% to 23%. Hüttenwerke Krupp Mannesmann (HKM) steel plant shows a gradual increase in activity from 42% in January 2025 to 48% in June 2025. Celsa France Boucau steel plant maintains a consistently high activity level, varying between 43% and 47%.

Donetsksteel Metallurgical Plant, located in Donetsk, Ukraine, is an integrated BF steel plant with a 1.5 million ton iron production capacity. While BOF and EAF are listed as main equipment, BOF are dismantled and the EAF mothballed. The satellite data reveals a gradual increase in activity from 17% in March 2025 to 23% by June 2025. However, we could not establish a direct link between this activity and the provided news articles.

Hüttenwerke Krupp Mannesmann (HKM) steel plant, situated in North Rhine-Westphalia, Germany, operates as an integrated BF-BOF plant with a crude steel capacity of 6 million tons and an iron capacity of 5.2 million tons. The plant’s activity has gradually increased from 42% in January 2025 to 48% in June 2025. Again, we could not establish a direct link between this activity and the provided news articles.

Celsa France Boucau steel plant, located in Nouvelle-Aquitaine, France, is an EAF-based plant with a crude steel capacity of 1.2 million tons. The activity level remains relatively stable and high, ranging between 43% and 47% throughout the monitored period. We could not establish a direct link between this activity and the provided news articles.

Based on the news articles about ArcelorMittal Eisenhüttenstadt, a temporary supply disruption is anticipated due to the shutdown of blast furnace 5A, which has a 1.7 million tons annual capacity. Given this temporary reduction in supply, steel buyers should consider the following actions:

  • Short-Term Procurement: Steel buyers reliant on ArcelorMittal Eisenhüttenstadt should secure alternative supply sources or increase inventory levels to mitigate potential short-term disruptions during the shutdown period (June 22nd to June 27-28th, 2025).
  • Price Monitoring: Closely monitor spot market prices for potential fluctuations due to the temporary supply reduction.
  • Supplier Diversification: Evaluate and diversify the supplier base to reduce dependence on a single source, especially for critical steel grades produced by ArcelorMittal Eisenhüttenstadt.
