Background to the reassessment
Hydrogen cyanamide was reassessed in 2006. Based on new information, grounds for reassessment were established in 2019.
Hydrogen cyanamide was last reassessed in 2006. It was decided that risks would be managed by an industry-led approach to ensure safe use of hydrogen cyanamide substances.
Grounds for reassessment
Grounds for reassessment were established in September 2019 based on new information on the effects of hydrogen cyanamide.
The new information included the European Food Safety Authority review and associated human health and environmental risk assessments, and the subsequent European Union decision implementing the authority's recommendations.
Call for information
We opened a public call for information about hydrogen cyanamide at the start of 2020. It closed on 29 May 2020, and we received 12 responses. The information provided has been used to inform this reassessment application.
