Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Zirconium carbide is considered to be highly insoluble in water and non-toxic to fish at a nominal concentration of 100 mg/L. Acute toxicity data for daphnia, algae and activated sludge are not available. However, due to the high unsolubility and evidence from acute toxcity testing in fish, aquatic toxicty is considered unlikely and further testing is considered scientifically unnecessary.
Conclusion on classification
No relevant hazard is identified. The available aquatic toxicity data do not give rise for concern regarding adverse effects of the substance to the environment. Classification of zirconium carbide as hazardous to the aquatic environment is therefore not required.
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.
