Market
Argentina is a producer and exporter of walnuts (Juglans regia), with orchards concentrated in Mendoza, Catamarca, La Rioja, San Juan and Río Negro. The market is export-oriented, but domestic demand remains meaningful and official sources note that local production has not always fully covered internal consumption. Trade is shaped by SENASA quality rules and destination phytosanitary protocols, especially for access to China and other importing markets.
Market RoleProducer-exporter with domestic import supplementation
Domestic RoleDomestic snack and ingredient market with supplementary imports for balance
SeasonalityMain harvest runs from April to June, followed by drying, grading and packing.

Physical Attributes- Uniform kernel color is a commercial criterion
- Well-filled nuts and kernels are preferred
- Low moisture is required for shelled product
- Defect tolerance is tightly controlled in grading
- Shell integrity and kernel brightness matter for buyer acceptance
Compositional Metrics- Shelled nuts must not exceed 5% moisture
- Rancidity and acidity limits are part of quality grading
- Kernel color class is used for commercial evaluation
- Defect percentages are defined by official classification
Grades- Three commercial quality categories for in-shell nuts
- Three commercial quality categories for shelled nuts
- Color classes based on the USDA color chart
- Defect tolerances expressed as percentage of the sample
Packaging- Labels must show species, variety, producing province, packer/exporter, harvest year, category, net weight and calibre
- For shelled nuts, labels must also show type and color
- Packaging and transport must preserve quality and arrive in good condition
Supply Chain
Value Chain- Harvest -> drying -> shelling or cracking -> sorting and grading -> packing -> domestic/export distribution
Temperature- Cool, dry storage is preferred; walnuts do not need a fresh-produce cold chain, but heat speeds rancidity
- Temperature control is mainly about protecting quality rather than preserving freshness
Atmosphere Control- Low humidity and clean storage are essential
- Moisture pickup raises mold and quality-loss risk
- Pest exclusion matters more than modified-atmosphere handling
Shelf Life- Properly dried walnuts store well, but shelf life falls if moisture, rancidity or insect contamination rises
- Quality is highly dependent on post-harvest drying and clean packaging

Risks
Regulatory Compliance HighA shipment can be delayed or rejected if it fails SENASA walnut quality rules or the destination protocol's quarantine-pest and contamination checks.Pre-clean, sort and document lots; verify labels and packer registration; run destination-specific pre-shipment inspections.
Food Safety MediumWalnuts are vulnerable to mold, rancidity and off-flavors if drying or storage is poor; the national standard explicitly sets moisture, defect and rancidity limits.Dry promptly to spec, keep humidity low, and store in clean sealed facilities.
Climate MediumProduction is exposed to climate variability, and INTA has bred lower-chill walnut varieties because changing conditions can affect orchard performance.Diversify varieties and orchards, and apply frost and irrigation management.
Market Volatility MediumExport earnings are concentrated in a few destinations, and official export prices differ sharply between in-shell and shelled walnuts, so pricing can swing with mix and demand.Diversify buyers and keep a mix of in-shell and shelled sales channels.
Sustainability- Irrigation-water stewardship in Cuyo and Northwest orchards
- Climate adaptation through lower-chill varietal selection
Labor & Social- Seasonal harvest and packhouse labor demand peaks between April and June
FAQ
How are Argentine walnuts graded?Argentina's walnut rule classifies in-shell and shelled walnuts into three quality categories. It also uses size, color and defect tolerances, and shelled nuts must stay at or below 5% moisture.
Which provinces produce most walnuts in Argentina?The main producing provinces are Catamarca, La Rioja, Mendoza, San Juan and Río Negro.
When is the main harvest season?The main walnut harvest window is April to June.
Where do Argentina's walnut exports go?Official 2022 data show Italy and Brazil among the leading destinations, with the United Arab Emirates and Turkey also important.
