Market
Chile is a major producer and exporter of walnuts, with orchards concentrated in the central belt around Metropolitana, O'Higgins, and Maule. The market is strongly export oriented, with both in-shell and shelled walnuts shipped through the year from an autumn harvest that starts in April and May. ODEPA reported walnut export value of USD 644.4 million FOB for the April 2025 to March 2026 season, while planted area has recently contracted as growers faced price pressure and crop substitution. Water stress and climate variability in central Chile remain the main structural supply constraints.

Supply Chain
Value Chain- Harvest -> dehusking -> drying -> sizing and sorting -> shelling if needed -> packing -> export dispatch
Temperature- Dry, cool storage with temperature control is important
- Heat and moisture exposure can accelerate quality loss
Atmosphere Control- Low-humidity storage and packaging help preserve quality
- Moisture ingress is a key handling risk
Shelf Life- Shelf life depends on drying quality, humidity control, and storage hygiene
- Poor handling can lead to mold, rancidity, or discoloration
Freight IntensityLow
Transport ModeSea
Risks
Climate HighCentral Chile's drought and irrigation stress can cut yields, delay harvests, and reduce walnut quality because production is concentrated in the Metropolitana, O'Higgins, and Maule belt.Prioritize irrigated orchards, water-management plans, and diversified sourcing across regions.
Price Volatility MediumWalnut area has contracted as growers switched to more profitable crops, showing that low-price cycles can reshape supply and availability.Use forward contracts and monitor planted-area trends.
Regulatory Compliance MediumDestination phytosanitary rules change by market, and an outdated requirement or missing certificate can hold a shipment at the border.Verify destination rules in SAG's country tool and with the buyer before shipment.
Food Safety MediumPoor drying or humid storage can trigger mold, rancidity, or residue and mycotoxin issues that buyers may reject.Enforce drying, humidity control, and lab release protocols.
Logistics MediumFreight timing and port congestion affect margins on long-haul exports, even though walnuts are less freight-sensitive than fresh produce.Book container space early and maintain buffer inventory.
Sustainability- Water scarcity and irrigation pressure in central Chile

FAQ
Which walnut variety leads the Chilean market?Chandler is the main commercial variety in Chile. Serr and Howard are the earlier varieties that start the harvest.
Is Chile mainly exporting walnuts or selling them domestically?Chile is mainly an export market for walnuts. Most production is shipped abroad, and ODEPA reported exports to 38 countries in the April 2025 to March 2026 season.
What document matters most for export clearance?The most important entry document is the phytosanitary certificate issued by SAG when the destination market requires it.
What quality controls matter most for Chilean walnuts?Exporters focus on lot traceability, dry storage, and lab checks for moisture, mycotoxins, and pesticide residues.
