Argentina's food and agriculture safety authority has introduced new labelling rules for pesticides and agricultural chemicals, overhauling a standard that had been in place since 2014.

The resolution, published by SENASA, the Servicio Nacional de Sanidad y Calidad Agroalimentaria, on 24 April 2026, makes the United Nations' 9th version of the Globally Harmonised System of Classification and Labelling of Chemicals, known by its Spanish acronym SGA, mandatory for all pesticide products sold in Argentina. The previous regulation, Resolution 367/2014, is now revoked.

The change affects anyone who holds a registered pesticide product for sale in Argentina. Under the new rules, labels must classify hazards to human health, the environment, and non-mammalian species according to the UN's 9th version of the SGA standard, and must display the corresponding pictograms and warning phrases. Personal protective equipment guidance must follow icons recommended by the UN Food and Agriculture Organisation.

Labels are now required to be structured in three distinct sections: product identification, safety precautions, and usage recommendations. The background must be white with black text, medical information must appear in a specific shade of red, and the minimum font size is eight typographic points. All text must be in Spanish, with the exception of trade names and scientific names.

The resolution also introduces specific requirements for particular product categories. Garden-line products must carry a prominent warning that they should not be used indoors. Products registered through a mutual recognition arrangement with other countries must carry a notice making clear they were authorised without SENASA conducting its own independent technical review. Products registered for export only must be clearly marked as not permitted for sale or use within Argentina.

The five annexes are the technical detail sitting behind the main resolution. Together they specify exactly what must appear on a pesticide label and how hazards must be categorised and communicated.

Penalties for non-compliance, including suspension or cancellation of a product's registration, will be applied under Argentina's existing agricultural health law.

The regulation took effect the day after its publication in the official gazette, on the 25th of April.
