This is a list of the largest steel-producing companies in the world mostly based on the list by the World Steel Association. This list ranks steelmakers by volume of steel production in millions of tonnes and includes all steelmakers with production over 10 million in 2021. The World Steel Association compiles a list from its members every year. Note that due to mergers, year-to-year figures for some producers are not comparable. Also note that not all steel is the same; some steel is more valuable than other steel, so volume is not the same as turnover.
