Argentina’s National Agri-Food Health and Quality Service (SENASA) has issued Resolution 373/2026, establishing updated pesticide labeling requirements for phytosanitary products marketed in Argentina. The resolution was published in the Official Gazette on April 24, 2026, and entered into force on April 25, 2026. It adopts the guidelines of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS/SGA) for phytosanitary product labeling, covering hazard classification, pictograms, signal words, hazard statements, label structure, language, typography, and mandatory label content.
For agrochemical manufacturers, exporters, importers, distributors, and local registration holders, the key compliance message is clear: labels for phytosanitary products commercialized in Argentina must be reviewed against SENASA Resolution 373/2026 and its GHS-based labeling requirements.
Argentina Pesticide GHS Regulation: What Has Changed?
According to SENASA Resolution 373/2026, the new labeling framework introduces updated requirements for hazard communication, label structure, and mandatory markings for phytosanitary products. The core changes are summarized below.
Adoption of GHS-based hazard communication
The classification of hazards to human health must follow UN GHS document ST/SG/AC.10/30/Rev.9, or any replacement version subsequently defined by SENASA’s Directorate of Agrochemicals and Biologicals. Labels must adopt the applicable GHS pictograms, signal words, and hazard statements. In addition, pictograms for personal protective equipment (PPE) must follow the recommendations of the Food and Agriculture Organization of the United Nations (FAO).
Standardized label structure and layout
Labels must be organized into three sections: the identification section, the use precautions section, and the use recommendations section. From a layout perspective, labels must use a white background with black text. The “medical information” section must appear in red, Pantone 199 C, and the minimum print size must be 8 typographic points, with 1-point line spacing.
Specific marking requirements for certain product categories
Technical-grade active substances: labels must include the active substance name, SENASA registration number, country of origin, minimum purity, batch number, applicable GHS hazard categories and precautions, and manufacturing establishment information.
Seed treatment products for exclusive use by seed companies: labels must clearly include the statement “USO EXCLUSIVO PARA SEMILLEROS” where applicable.
Garden-line products: labels must prominently display the statement “NO APLICAR EN EL INTERIOR DE LA VIVIENDA” in the identification section.
Export-only phytosanitary products: the product registration number must be preceded by “S.E.” and the label must include the statement “EL PRODUCTO NO PODRÁ SER COMERCIALIZADO NI UTILIZADO EN EL TERRITORIO NACIONAL.”
Impact for Agrochemical Companies
This regulatory update creates a direct compliance obligation for companies involved in the production, commercialization, import, or export of phytosanitary products in Argentina. By aligning pesticide labeling with GHS-based hazard communication, Argentina aims to improve hazard transparency and bring its labeling framework closer to internationally recognized standards.
Companies should also note the enforcement implications. Under Article 18 of Resolution 373/2026, SENASA may suspend or cancel the registration of a phytosanitary product where unauthorized changes to the product’s composition, dose, application conditions, toxicological class, or other label specifications are inconsistent with the approved registration. Therefore, label compliance is not only a formatting matter, but also a regulatory obligation linked to the validity of the product registration.
Recommended Actions for Companies Supplying the Argentine Market
In response to these regulatory changes, companies placing phytosanitary products on the Argentine market should consider the following actions:
Conduct an internal label compliance review: Regulatory, technical, and artwork teams should review labels for existing and upcoming products against the complete label model and elementary label model attached to Resolution 373/2026. The review should cover GHS pictograms, signal words, hazard statements, toxicological bands, PPE pictograms, color rules, typography, Spanish-language text, and overall label structure.
Verify hazard classification and mandatory statements: Companies should confirm whether human health hazard classification aligns with UN GHS Rev. 9 as referenced by SENASA, and whether environmental, toxicological, and non-mammalian hazard elements are correctly reflected according to the relevant annexes. Mandatory statements for specific product categories should be checked carefully.
Strengthen label-registration consistency controls: Product composition, concentration, dose, application conditions, use instructions, toxicological class, restrictions, and other label specifications should be cross-checked against the approved registration dossier to avoid inconsistencies that could lead to enforcement action.
Assess specialized product lines separately: Export-only products, technical-grade active substances, seed treatment products, industrial wood preservatives, garden-line products, and products registered through regulatory convergence may require additional or category-specific label statements.
Resolution 373/2026 represents an important step in Argentina’s alignment with international hazard communication standards for phytosanitary products. Given that the resolution has already entered into force, relevant stakeholders should promptly initiate label reviews and compliance adjustments to reduce regulatory and market access risks.
