Market
In-shell hazelnut is a flagship Turkish tree-nut export, with production concentrated along the Black Sea belt. Harvest maturity is typically reached in August, after which nuts are dried to stabilize quality for storage and export. The market is strongly quality-driven, with trade references such as “Giresun quality” and “Levant quality” commonly used in commercial positioning. Food-safety compliance—especially mycotoxin (aflatoxin) control—is a recurring requirement for access to strict importing markets.
Market RoleMajor producer and exporter
Domestic RoleSignificant domestic processing and snack consumption alongside an export-oriented value chain
SeasonalityMain harvest maturity is in August in the Black Sea production belt; timing varies with latitude and field conditions, followed by a drying period that is weather-dependent.
Risks
Food Safety HighAflatoxin contamination risk can block access to strict importing markets: shipments that do not comply with destination maximum levels (e.g., EU limits under Regulation (EC) No 1881/2006) can face rejection, recall, or intensified controls, creating acute commercial loss and reputational damage for Turkish hazelnut exporters.Implement moisture-controlled drying/storage, run pre-shipment accredited lab testing for aflatoxins by lot, and align sampling plans with destination official-control methodologies; maintain documented HACCP and supplier QA programs.
Labor and Human Rights MediumChild labor allegations in Turkish hazelnut harvesting create buyer and regulatory due-diligence exposure; some customers may suspend suppliers without credible monitoring and remediation programs.Adopt a documented child-labor prevention program, ensure worker-age verification and grievance channels, and commission independent third-party audits during harvest season.
Climate MediumYield and quality volatility from adverse weather (e.g., frost, storms, drought stress) in the Black Sea belt can tighten supply and raise price volatility, impacting contract performance and margin stability.Diversify sourcing across Black Sea sub-regions, use conservative contract cover during high-risk weather windows, and maintain inventory buffers aligned to buyer programs.
Logistics LowWhile hazelnuts do not require cold chain, moisture exposure during storage/transit can degrade quality and increase mold/mycotoxin risk; seasonal shipment clustering can also increase delay risk.Use humidity-protective packaging and clean, dry containers; apply inbound/outbound moisture checks and container inspection protocols.

- Soil and hillside orchard management considerations (erosion and orchard aging risks in some areas)
Labor & Social- Child labor due diligence risk: U.S. Department of Labor ILAB lists hazelnuts from Türkiye as a good with reason to believe it is produced with child labor.
- Seasonal labor conditions and recruitment practices in harvest periods can create heightened social-compliance scrutiny from international buyers.

FAQ
When is the typical harvest period for Turkish in-shell hazelnuts?In the Black Sea production belt, hazelnuts generally mature in August, with timing varying by latitude and orchard conditions; a drying period follows harvest to stabilize quality for storage and trade.
What is the most critical compliance risk for exporting Turkish hazelnuts to strict markets such as the EU?Aflatoxin compliance is the key risk: the EU sets maximum levels for aflatoxins in nuts under Regulation (EC) No 1881/2006, and non-compliant lots can be rejected or recalled, so exporters typically manage this through controlled drying/storage and lot-based laboratory testing.
Why do buyers ask for social compliance assurances in Turkish hazelnut supply chains?Because hazelnuts from Türkiye are listed by the U.S. Department of Labor ILAB as a good with reason to believe it is produced with child labor, many international buyers require documented prevention, monitoring, and remediation measures during harvest season.
