Brazil: WTO Notification and public consultation for diverse chemical substances

2021-02-20

The Brazilian Health Regulatory Agency (ANVISA) has been submitting several proposals of the country’s agrochemical standards to the WTO in February. All of the modification proposals are open to public consultation until April 4th, 2021.

These proposals can be seen as a part of the National Fertilizer Plan and the country’s determination to enhance registration of pesticides. Most of WTO notifications are related to the modification of Maximum Residue Limit (MRL), Safety Interval (SI), and Acute Reference Dose (ARfD).

The correlation of chemicals and modifications is displayed in the following table.
