U.S. steel production in 2010 was projected to be 38% more than that in 2009. Imports of manganese materials were significantly more in 2010 than in 2009--82%, 104%, and 139% more for manganese ore, ferromanganese, and silicomanganese, respectively. As a result, U.S. manganese apparent consumption increased.
