Dossiers Successfully Updated: Manganese Ores, Reduced (EC 273-748-0)&Slags, SiMn-manufacturing (EC273-733-9)

The submitted dossier was accepted by the ECHA in Feb/March 2025. The List below is a brief outline of the sections updated within the dossier.

Dossier sections

• C&L updated to remove Cat 2 reprotoxicity classification
• Waiver included for developmental toxicity study in second species (rabbit).
• DNELs updated as these were based on FeMn slag rabbit reprotox study.
• TK assessment updated to remover references to FeMn slag rabbit reprotox study.
• General tidy-up removal of all ‘migrated information/data’ phrases from latest software update
• Updated waivers to be reported correctly including: boiling point, vapour pressure, partition coefficient, surface tension, flash point, flammability in water, explosivity, stability, dissociation constant and viscosity. Hydrolysis, biodeg, inhalation toxicity.
• CSR updated for consistency to dataset
• RAAF Updated for consistency with dataset.
• Several Validation/IUCLID software related errors addressed

Overall, the concerns raised regarding the presence of SiO2  and its potential hazards were addressed as well as reproductive toxicity concerns that emanated from the study on the analogue substance FeMn slags.

With regards to classification and labelling, the updated Sinter ore dossier is classified an Eye irritant cat 2; H319: causes serious eye irritation. Meanwhile the SiMn slags registration remain unclassified
