Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on the available information it appears that he slightly soluble zinc oxide and insoluble zinc sulphide are not skin irritants and therefore slightly soluble zinc hydroxide, zinc phosphate, zinc carbonate and zinc metal are also expected to be not irritating to skin. Zinc oxide, zinc phosphate, zinc metal and zinc sulphide are not eye irritants and therefore zinc carbonate and zinc hydroxide are also expected to be not irritating to eyes. None of the slightly soluble or insoluble zinc compounds appear to cause respiratory tract irritation.
The slightly soluble and insoluble zinc compounds (zinc oxide, zinc hydroxide, zinc phosphate, zinc carbonate, zinc metal and zinc sulphide) are not corrosive based on the available irritation data.
Justification for classification or non-classification
The slightly soluble and insoluble zinc compounds ( zinc oxide, zinc hydroxide, zinc phosphate, zinc carbonate, zinc metal and zinc sulphide)
are not irritating or corrosive based on the available irritation data and therefore no classification is required according to EC criteria either for irritation or corrosion. Copper content in GSS is highly low (about 100 ppm), and bonded to the structure of ZnS (Zn is partially substituted with Cu), so the effect of copper on the classification of the registered substance can be ignored.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.
