Market
In-shell hazelnut (Corylus spp.) is a globally traded tree nut supplied primarily from temperate orchard systems, with overall production strongly concentrated in Türkiye and a secondary production base in Italy, the Caucasus (Azerbaijan/Georgia), the United States, and Chile. While Türkiye dominates global hazelnut availability overall, in-shell trade (HS 080221) has distinct patterns, with Italy and China among the largest import markets and the United States and several European suppliers prominent in reported in-shell export flows. Commercial transactions commonly reference UNECE’s DDP-03 standard for sizing, classes, and tolerances, while food safety controls focus heavily on preventing mould growth and aflatoxin contamination through good drying and storage practices. Global market dynamics are highly sensitive to weather and pest shocks in major origin regions, which can rapidly tighten supply and increase price volatility for downstream confectionery and snack channels.

Specification
Major VarietiesTombul, Çakıldak, Palaz, Foşa, Tonda Gentile delle Langhe, Tonda di Giffoni, Barcelona
Physical Attributes- In-shell hazelnuts are traded free from husk/involucre; intact, clean shells are core quality requirements in UNECE DDP-03.
- Sizing is determined by shell diameter; uniform size ranges (calibers) are commonly specified for premium classes.
Compositional Metrics- Moisture management is a primary commercial and safety control point because excessive moisture increases mould and mycotoxin risk.
- Rancidity and off-odors are key defect considerations for acceptance, especially for long storage and shipment.
Grades- UNECE DDP-03 classes: “Extra” Class, Class I, Class II (with defined minimum requirements, sizing provisions, and defect tolerances).
Packaging- Bulk sacks (e.g., woven polypropylene/jute) and bulk cartons are common for trade; packaging must protect shells from moisture uptake and contamination.
- Lots are commonly packed and labeled by origin, size/caliber, class, crop year/lot code, and food safety controls where applicable.
ProcessingPrimary post-harvest handling includes drying, cleaning, and grading before storage and export.Downstream use often involves shelling/cracking, sorting, and (for many applications) roasting before ingredient manufacturing.
Supply Chain
Value Chain- Orchard harvest (ground collection or hand-pick) -> field/yard drying -> cleaning/dehusking removal -> grading & sizing -> storage -> export shipping -> destination sorting -> retail in-shell or shelling/roasting for ingredient use
Demand Drivers- Confectionery and spreads (industrial ingredient demand) in Europe and other major consumer markets
- Snack consumption of whole nuts in-shell and at-home cracking in select markets
- Premium sourcing programs and origin/quality differentiation (size, class, defect rates)
Temperature- Dry, cool storage is essential to prevent mould growth and reduce aflatoxin risk; moisture ingress during storage and transport is a key failure mode.
- Quality preservation is strongly tied to maintaining low relative humidity environments and avoiding condensation within packaging/containers.
Shelf Life- In-shell hazelnuts generally have longer keeping quality than kernels when properly dried and stored, but quality can deteriorate through rancidity or mould if temperature/humidity control fails.
Risks
Climate HighGlobal hazelnut availability and pricing are highly exposed to climate and pest-driven yield shocks in Türkiye’s Black Sea production zone, the dominant global supply base; spring frost, storms, and pest outbreaks can materially reduce usable crop and trigger sharp price volatility that propagates through confectionery and snack supply chains.Diversify origin exposure (multiple hemispheres and regions), use pre-harvest forecasting and crop-condition monitoring, and maintain contingency inventories/forward coverage for critical SKUs.
Food Safety HighAflatoxin contamination risk increases when nuts are not dried adequately or are exposed to moisture during storage/transport; this can cause shipment rejections, recalls, and tightened import controls.Apply Codex-aligned practices for aflatoxin prevention (GAP/GMP, rapid post-harvest drying, hygienic storage, segregation of suspect lots, and robust sampling/testing programs).
Plant Health MediumDiseases and pests (e.g., Eastern filbert blight in hazelnut-growing regions and quality-damaging insects) can constrain production expansion, increase costs, and reduce exportable quality.Adopt resistant cultivars where available, strengthen integrated pest management and orchard hygiene, and invest in monitoring and rapid response capacity.
Market Volatility MediumA concentrated supply base combined with weather-driven crop variability can create repeated cycles of tight supply and price spikes, complicating procurement and contract performance for manufacturers.Use multi-year sourcing strategies, diversify specifications (sizes/classes) where feasible, and structure contracts with quality/availability contingencies.
Regulatory Compliance MediumImport compliance can tighten rapidly following food safety incidents (mycotoxins, pests, foreign matter), increasing documentation, testing, and border delays for exporters and importers.Align product specs to UNECE quality standards, implement documented HACCP-based controls in packing/handling, and maintain transparent lot-level traceability and testing records.
Sustainability- Climate vulnerability in major origin regions (notably Türkiye’s Black Sea area) where heat waves, shifting rainfall, and severe storms can reduce yields and disrupt livelihoods.
- Orchard aging and agronomic constraints (site suitability, disease pressure) can limit expansion and raise long-term supply risk in key producing regions.
Labor & Social- Child labour risk and broader decent-work concerns in seasonal hazelnut harvesting in Türkiye have been a sustained focus of ILO public-private partnership programs.
- Reliance on seasonal/migrant labor and labor intermediaries increases due diligence and traceability expectations for global buyers.
FAQ
Which countries are most important globally for in-shell hazelnut production and trade?Overall hazelnut production is concentrated in Türkiye and Italy, with additional significant production in Azerbaijan, Georgia, the United States (notably Oregon), and Chile. For in-shell trade (HS 080221), recent UN Comtrade/WITS snapshots show Italy and China among the largest import markets, while the United States and several European suppliers (e.g., Spain and France) are prominent in reported export flows.
What is the main international quality reference for in-shell hazelnuts?A widely used reference is UNECE Standard DDP-03 for inshell hazelnuts, which defines minimum quality requirements and commercial classes (“Extra”, Class I, Class II), along with sizing and defect tolerance provisions.
What is the single biggest global risk that can disrupt hazelnut supply and pricing?Weather and pest-driven yield shocks in Türkiye’s Black Sea production zone are the most critical disruption risk because that region underpins global availability; frost, storms, and pest outbreaks can sharply reduce usable crop and quickly raise prices downstream.
What major labor and social issue is associated with hazelnut harvesting in Türkiye?Child labour risk and related decent-work concerns in seasonal hazelnut harvesting have been documented as an issue significant enough to drive multi-year ILO public-private partnership programs with industry and other stakeholders focused on prevention and remediation.
