Notes on company ownership and tonnage calculations:
For worldsteel members, the data was sourced from their official tonnage declarations. In case of more than 50% ownership, 100% of the subsidiary’s tonnage is included, unless specified otherwise. In cases of 30%-50% ownership, pro-rata tonnage is included. Unless otherwise specified in the declaration, less than 30% ownership is considered a minority and therefore, not included. Figures represent ownership ending 31 December {{filters.year}}.
