Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
Justification for classification or non-classification
Tetrabasic lead sulphate does not require classification for explosiveness.
The study does not need to be conducted because there are no chemical groups present associated with explosive properties.
The experimental determination of the explosivity of a compound is not required, if available thermodynamic data (reaction enthalpies) and/or the absence of certain reactive groups (Bretherick, 1990) in the structural formula indicate that the substance will not decompose violently under formation of gases or release of energy and thus does not pose a risk for explosivity.
The substance consists of lead cations and the sulphate anion which can all be considered as “inert” in the context of explosivity, since it already represents lead in an elevated oxidation status. It is also noted that despite the long-term industrial handling, this substance is not classified for explosive properties according to UN transport regulations.
The study is therefore waived in accordance with REACH Annex VII, Section 7.11, Column 2.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
