The regional distributions of coke, coking coal, iron ore, lime, and steel scrap exhibit the dominance of the USA in supplying these raw materials for automotive steel. Coke is primarily sourced from the RFC (67%) and SERC (10%) regions in large part because those are the regions where most crude steel is produced in the USA.
