In Paraguay, fertilisers and plant biostimulants are regulated primarily under the authority of the Servicio Nacional de Calidad y Sanidad Vegetal y de Semillas (SENAVE), which operates under the Ministerio de Agricultura y Ganadería(MAG). SENAVE is responsible for overseeing the quality, control, importation, and commercialisation of agricultural inputs used in crop production, including fertilisers and related products.

The main legislative basis for SENAVE’s authority is Law No. 2459/2004 establishing SENAVE, which created the institution and granted it regulatory competence over plant health, seeds, and agricultural inputs.

Although Paraguay does not appear to have a single consolidated fertiliser law comparable to those adopted in some other jurisdictions, SENAVE issues resolutions and administrative procedures governing the registration, control, and commercialisation of fertilisers and similar products placed on the Paraguayan market.

In practice, fertilisers generally need to be registered with SENAVE before they can be imported, distributed, or commercialised in Paraguay.

The registration process typically requires the submission of a technical dossier describing the product’s composition, manufacturing process, specifications, and labelling. Applicants must normally appoint a locally established company or representative responsible for the product in Paraguay, and the importer or distributor must also be registered with SENAVE. The authority reviews the documentation to verify the product’s composition and compliance with national quality and labelling requirements before granting authorisation for marketing.

Plant biostimulants do not appear to be regulated under a specific standalone regulatory category in Paraguay. In practice, they are usually assessed under the broader framework applicable to fertilisers, soil conditioners, or other crop input products depending on their composition, mode of action, and the claims made for the product. Consequently, biostimulant products intended for agricultural use generally follow the same administrative procedures applied to fertilisers or similar inputs.

Publicly available information on official registration fees and processing timelines for fertilisers or biostimulants in Paraguay is limited. The specific costs and evaluation timelines are typically determined through administrative procedures and SENAVE resolutions and may vary depending on the type of product and the completeness of the dossier submitted. As a result, the precise registration cost and expected processing time usually need to be confirmed directly with SENAVE or through a local regulatory representative.

Even if a fertiliser or plant biostimulant is already authorised or marketed in other countries—such as Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, Panama, Cuba, Argentina, Bolivia, Brazil, Chile, Colombia, Peru, Uruguay, or Venezuela—this does not automatically grant market access in Paraguay. Paraguay generally requires a national registration or authorisation procedure before a product can be legally marketed within its territory. However, documentation from other jurisdictions, such as certificates of free sale or existing product registrations, may sometimes be submitted as supporting information in the application dossier.

Overall, the Paraguayan regulatory framework for fertilisers and plant biostimulants is primarily implemented through SENAVE’s administrative procedures rather than through a single detailed fertiliser law. Consequently, companies seeking to place such products on the Paraguayan market typically work with a locally established importer or regulatory representative to manage the registration process and ensure compliance with national requirements.
