Boundary Composition

What is a Boundary Composition?

The IUCLID 6 software enables the reporting of so-called boundary compositions of the substance. These compositions describe the boundaries of the collectively registered substance of the joint submission, and should reflect the hazard information and classification provided for the substance. The boundary compositions are to be reported in the lead registrant dossier and linked to relevant information (C&L, PBT). More than one boundary composition can be provided; together, these compositions are expected to reflect the Substance Identity Profile (SIP). Information provided in boundary composition records is extracted to the REACH-IT Joint submission page and displayed to the participants of the joint submission.

PBT/vPvB assessment: None necessary for Molybdenum Consortium portfolio substances as an assessment is not required for inorganic substances, according to Annex XIII of the EU REACH Regulation EC 1907/2006.
