Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Nickel Nitrate is classified as having oxidizing properties.
Key value for chemical safety assessment
- Oxidising properties:
- yes
Additional information
The criteria for packaging group III given in the UN Transport Manual of Tests and Criteria (UN, 1999) require that the mean burning time for a 4:1 or 1:1 sample-to-cellulose ratio (by mass) exhibits a mean burning time equal to or less than the mean burning time of a 3:7 mixture (by mass) of potassium bromate and cellulose (and the criteria for packaging groups I or II are not met).
As cited in the 2008/2009 EU Risk Assessment for nickel nitrate, the test result given in the Manual for nickel nitrate is 101 s, which is just higher than the limit for classification in class 5.1 (100 s for a 3:7 potassium bromate sample). This result is reported as negative (“Not 5.1"), which implies that the substance as tested did not belong to class 5.1 (UN, 1999) and should not be classified.
However, according to the CLP classification, nickel nitrate is classified as a Category 2 Oxidizing Solid. In the absence of any additional data to provide further evidence that the substance is not oxidising, the CLP classification will be accepted. Thus, nickel nitrate is indicated to have oxidizing properties.
Justification for classification or non-classification
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.
