Operator history (post-MRDS)

MRDS records operators as of each record's last update (≤ 2019). Some of the operators listed here have since changed hands or dissolved:

  • Cleveland-Cliffs Iron Co. — renamed to Cleveland-Cliffs Inc. (2017)
    Reorganized and renamed Cleveland-Cliffs Inc. in 2017 as the parent shifted from iron-ore focus to steelmaking.
