Product Origination

When raw materials used to produce steel originate in the U.S., this initial procurement decision can contribute not only to the sustainability of Cleveland-Cliffs’ supply chain but to the sustainability of the country. A healthy steel industry plays an important role in the growth of the U.S. economy, the general welfare of the populace and the national security of the country. Beyond this initial contribution, steel is infinitely recyclable and can be reproduced without the loss of performance.
