Raw chestnuts (Castanea sativa) in Chile are an emerging, seasonal tree-nut product with a commercially promoted “marrón” (marrons) type produced and packed for fresh export. A ProChile case study highlights Ñuble as a key producing area for the “marrón” segment, with harvest concentrated in April–May and export shipments typically running April–June. Export market development has been oriented to Europe (e.g., Spain and Italy) with reported initial diversification to Turkey via container shipments. For export, consignments must meet destination phytosanitary requirements and are typically supported by SAG inspection and issuance of a phytosanitary certificate.
Market RoleNiche producer and exporter (counter-season fresh chestnuts, led by the “marrón/marrons” segment)
Domestic RoleSeasonal domestic food product associated with winter consumption, alongside an export-oriented “marrón” segment
Market GrowthMixedexport niche development highlighted through regional exporter case studies
SeasonalitySeasonal harvest in April–May with a reported fresh export shipping window extending into June for the “marrón” segment.
Specification
Primary VarietyMarrón (marrons — non-septate nuts, where applicable)
Physical Attributes- In-shell sweet chestnuts with spiny husk removed (UNECE FFV-39 scope).
- Quality expectations include intact, sound, clean produce that is practically free from pests and pest damage (UNECE FFV-39 minimum requirements).
- Must be free of shrivelling/drying out, externally visible sprouting, abnormal external moisture, and foreign smell/taste (UNECE FFV-39 minimum requirements).
Grades- UNECE FFV-39 classes: “Extra”, Class I, Class II.
Packaging- Packaging must protect produce properly; internal packaging materials must be clean and non-damaging (UNECE FFV-39 presentation requirements).
- Marking typically includes class and size expression (by nuts/kg or diameter range) and may include “marrons” where applicable (UNECE FFV-39 marking requirements).
Supply Chain
Value Chain- Orchard harvest (Apr–May) → packing/selection → cold storage under low temperature and high relative humidity → sizing and final selection → export dispatch (Apr–Jun) (reported for the Ñuble “marrón” export segment).
- Export phytosanitary inspection and certification by SAG aligned to destination requirements.
Temperature- Low-temperature storage is reported post-harvest for export-oriented “marrón” chestnuts in Ñuble.
Shelf Life- Keeping quality is sensitive to perishability and post-export deterioration allowances are recognized in UNECE FFV-39, reinforcing the importance of handling discipline.

Risks
Phytosanitary HighMarket access for Chilean raw chestnuts can be blocked if destination phytosanitary requirements are not clearly identified and met, or if regulated pests/diseases are suspected or detected during inspection; chestnut is noted as susceptible to Cryphonectria parasitica and Phytophthora spp., which can heighten buyer and regulator scrutiny depending on destination rules.Use SAG’s destination-requirements system to confirm official conditions by country; implement orchard monitoring and pre-shipment sorting/inspection aligned to the destination protocol and ensure SAG certification workflows and attachments are complete.
Logistics MediumFresh export programs can face quality and commercial risk from ocean-freight volatility and delays, as post-harvest storage and handling conditions (low temperature and high relative humidity) are emphasized for the export segment highlighted by ProChile.Build conservative transit-time buffers, confirm cold-chain capable logistics partners, and align dispatch timing to the April–June export window described for the Ñuble “marrón” segment.
Quality Standards MediumBuyer rejection or downgrading risk can arise if consignments do not meet UNECE FFV-39 minimum requirements and class/size uniformity expectations (e.g., defects, decay, pest damage, sprouting, or inconsistent sizing).Align grading, sizing, and marking to UNECE FFV-39; document class/size and ensure packaging/marking compliance at pack-out.
FAQ
When are Chilean fresh chestnuts typically harvested and shipped for export?A ProChile case study for the Ñuble “marrón” segment describes harvest in April and May, with export shipments typically running from April through June.
What is the main regulatory gate for exporting raw chestnuts from Chile?Exports of plant products generally must meet the phytosanitary requirements of the destination country and are typically supported by SAG inspection and issuance of a phytosanitary certificate; SAG also provides a destination-requirements consultation system to identify the official conditions.
Which commercial quality classes are commonly used for in-shell sweet chestnuts in trade?UNECE FFV-39 classifies in-shell sweet chestnuts into three commercial classes: “Extra”, Class I, and Class II, alongside minimum quality requirements and sizing/marking rules.
