This is the Home Page of the SIEF for Iron, Einecs number 231-096-4, CAS number 7439-89-6 [no description is given in the Einecs definition]. The typical specification for Iron is given is given in the table below.

It was concluded that Iron [Einecs number 231-096-4] and Iron, Furnace [Einecs number 265-998-4] can be considered as the same substance for the purposes of REACH and that therefore the two SIEF's should be combined as Iron [Einecs number 231-096-4 CAS number 7439-89-6].   Iron therefore covers elemental iron, iron produced in a blast furnace or direct reduction plant, iron powders and carbonyl iron.   Each form of iron was considered individually for classification.   Click here to read the Iron Platform's Updated Statement on this issue in full.


Chemical analysis Value
Fe >80%

 No impurities present which would give rise to classification and labelling  issues.

Where the substance is an alloy containing iron, it is the only that iron itself that is covered by this specification, not the other constituents of the alloy and the iron can thus be considered as conforming to this specification.

For substances other than alloys, each registrant is responsible in case of need for explaining the composition of its substance in its own registration dossier, notably the difference between the actual Fe content and 100% purity.   Those with substances with Fe content lower than 80% will not be able participate in the joint submission; however they may use the dossier or studies for read across purposes.   If in doubt, please contact the Iron Platform.

The Lead Registrant for Iron is ArcelorMittal.   ArcelorMittal is supported by the Iron Platform Technical Working Group in this work and SIEF members should contact us with any questions that they may have about this process.   We will be posting relevant information on these pages from time to time.
