The 21st Meeting of the Chemical Review Committee (CRC-21) of the Rotterdam Convention on the Prior Informed Consent Procedure for Certain Hazardous Chemicals and Pesticides in International Trade was held in Rome, Italy from 23–26 September 2025. The CRC reviewed 35 notifications of final regulatory action related to 18 pesticides and three proposals for severely hazardous pesticide formulations (SHPFs). They found that many of the notifications and all of the SHPF proposals do not meet the criteria set out in the Convention. In particular, many of the national bans or restrictions were not taken after a risk evaluation based on the prevailing conditions of use in the country (criterion b(iii) in Annex II). Countries used other methods in line with their national legal frameworks and the information available to them.
The CRC deferred its consideration of five notifications because it could not agree whether the threshold for a risk evaluation was met. These include one notification from Mozambique on carbaryl and four from Malaysia.
