On July 23, 2019, the Agencia Nacional de Vigilancia Sanitaria (ANVISA -- National Sanitation Surveillance Agency) in Brazil approved measures that clarify the toxicological classification of agrochemicals. Under the approved rules, the evaluation criteria of agrochemicals’ toxicity categories are established and label requirements are updated to include clearer warnings and pictograms. The changes established by ANVISA were based on the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), aligning Brazil’s regulations with European Union (EU) and Asian countries, among others. With the aim of strengthening the commercialization of national products abroad, the approved rules allow one year for stakeholders to begin implementation. Out of the 2,300 agrochemicals registered in Brazil, ANVISA has already received information for the reclassification of 1,981 products.
