Market
Raw walnuts in Argentina are produced mainly in Catamarca, La Rioja, Mendoza, San Juan and Río Negro, with a mix of traditional “criolla” material and modern commercial cultivars. National output and export activity have expanded, with shipments including both in-shell and shelled walnuts and Italy and Brazil cited among key destinations in recent trade reporting. Exporters must meet destination-country sanitary and phytosanitary (SPS) requirements, with SENASA issuing phytosanitary export certification and maintaining market-entry requirement references. For quality language and defect tolerances, exporters commonly align lots to internationally used dry-produce standards for in-shell walnuts and walnut kernels.
Market RoleNet exporter with domestic consumption market
Domestic RoleDomestic consumption market supplied mainly by domestic production, with limited supplemental imports in some years
Market GrowthGrowing (mid- to late-2010s through early-2020s)export expansion with year-to-year volatility
SeasonalityHarvest is concentrated in Southern Hemisphere autumn; dried storage enables year-round marketing and export programs.
Risks
Food Safety HighMycotoxin (aflatoxin) contamination is a potential deal-breaker for export programs because key destination markets apply maximum levels and may impose border actions or intensified controls when limits are exceeded; tree nuts are among the food categories monitored for these hazards.Apply strict drying and storage controls, implement a mycotoxin monitoring plan with accredited pre-shipment testing for the target market, and maintain documented HACCP-style preventive controls through packing and storage.
Climate MediumFrost, hail, drought, and heat events can materially reduce yields and impair kernel quality; research in irrigated valleys highlights frost as a major productivity stress with a broad seasonal risk window in some production regions.Diversify sourcing across provinces, use frost/hail mitigation measures where feasible, and contract contingency volumes to cover severe weather seasons.
Regulatory Compliance MediumPhytosanitary non-compliance (missing/incorrect SENASA certification or mismatch vs. destination requirements) can trigger delays, additional inspections, or rejection in the importing market.Confirm destination entry requirements in SENASA references before contracting, run a pre-shipment document checklist, and align lot identity/traceability to certificate details.
Logistics MediumContainer freight volatility and transit disruptions can squeeze margins and disrupt delivery windows for bulk shipments from Argentina.Build buffer time into shipping schedules, lock freight when feasible, and maintain multi-carrier options during peak export periods.

FAQ
Which Argentine regions are most associated with walnut production?Official sector reporting and INTA materials commonly cite Catamarca, La Rioja, Mendoza, San Juan and Río Negro as key walnut-producing provinces in Argentina.
What phytosanitary step is essential to export raw walnuts from Argentina?For plant-origin exports, Argentina’s SENASA issues the phytosanitary export certificate to demonstrate compliance with the importing country’s phytosanitary requirements; exporters typically consult SENASA’s destination requirement references and then complete the certification process before shipment.
Which HS codes are commonly used for Argentina’s walnut exports?Argentina’s walnut trade reporting commonly references HS 0802.31 for in-shell walnuts and HS 0802.32 for shelled walnuts.
