SSAB welcomes the proposed carcinogen category 1B GCL 0.1% for cobalt metal as the majority of the iron ores mined within the European Union contain approximately up to 0.03 % cobalt metal by weight after reduction in the iron ore melting process, thus meaning all steel based upon those iron ores would have contained cobalt in excess of the RAC proposed SCL 0.01%. SSAB nevertheless questions the inclusion of cobalt in this ATP as more clarification is required regarding all routes of exposure, mutagenicity, the carcinogenic potency methodology and bio-elution as classification methodology for alloys.
