Market
In-shell hazelnut in the United States is a domestically produced tree-nut commodity with commercial production heavily concentrated in Oregon’s Willamette Valley. The market supplies domestic snack and ingredient demand and also supports export shipments, while some import flows can supplement availability depending on pricing and processor needs. Post-harvest drying and storage enable year-round commercial availability despite a seasonal harvest window. Production and quality risk are closely tied to Pacific Northwest orchard conditions and pest/disease management.
Market RoleProducer and exporter with supplemental imports
Domestic RoleDomestic consumption and ingredient supply for food manufacturing (snacks, bakery, confectionery) with a significant in-shell segment
SeasonalitySeasonal harvest with year-round availability enabled by drying and controlled storage.
Specification
Physical Attributes- Sound, dry in-shell nuts with low insect damage and minimal shell defects are typically required for in-shell retail and export programs.
Compositional Metrics- Moisture control after harvest is critical to reduce mold risk and protect shelf life; buyer specifications commonly include moisture/condition requirements.
Grades- Buyer specifications commonly screen for size uniformity and defect tolerances (e.g., blanks, mold, insect damage) for in-shell lots.
Packaging- Bulk bins/totes for handler intake and drying
- Bagged or carton-packed in-shell product for wholesale/retail programs depending on buyer requirements
Supply Chain
Value Chain- Orchard harvest (mechanical pickup) → cleaning/debris removal → drying and conditioning → sizing/sorting and defect removal → in-shell packing → storage → domestic distribution and/or export shipment
Temperature- Cool, dry storage conditions are used to slow rancidity and limit mold growth during longer holding periods.
Shelf Life- Shelf life depends heavily on post-harvest drying discipline, moisture control, and protection from heat and humidity during storage and transport.

Risks
Plant Health HighHazelnut supply is highly exposed to Pacific Northwest orchard pest and disease pressure; significant outbreaks or control failures (e.g., Eastern filbert blight in susceptible plantings) can reduce yields, downgrade quality, and disrupt contracted supply programs.Contract for resistant cultivars and validated orchard IPM practices; require handler QA documentation and diversify supply coverage across multiple growers/handlers and crop years.
Logistics MediumPort congestion, ocean freight volatility, or route disruptions can delay export shipments of bulky in-shell loads and pressure delivered margins.Build schedule buffers into export programs, secure bookings early in peak shipping windows, and maintain alternative routing/port options where feasible.
Food Safety MediumPost-harvest moisture or storage control failures increase mold and quality degradation risk, potentially triggering rejection or recall exposure in strict buyer programs.Implement validated drying/conditioning targets, storage monitoring, and lot-level QC/COA practices aligned to buyer requirements.
Sustainability- Orchard pesticide and integrated pest management scrutiny in intensive production areas
- Soil health and biodiversity practices in perennial orchard systems
- Climate variability impacts (heat, drought, wildfire smoke) affecting orchard productivity and nut quality in the Pacific Northwest
Labor & Social- Seasonal labor availability and compliance for orchard operations (including worker safety and lawful employment practices)
- Contractor management and worker protections during harvest and post-harvest handling
Standards- GFSI-benchmarked food safety certification (e.g., BRCGS, SQF) commonly requested by large retail/CPG buyers
- HACCP/FSMA-aligned preventive controls in handling/processing facilities
FAQ
Where is U.S. in-shell hazelnut production concentrated?Commercial U.S. hazelnut production is concentrated in Oregon, particularly the Willamette Valley, which anchors the main grower-to-handler supply base for in-shell programs.
Is U.S. in-shell hazelnut supply available year-round?Yes. While harvest is seasonal, drying and controlled storage allow handlers to supply in-shell hazelnuts year-round, with quality depending on moisture control and storage conditions.
What are commonly required documents to import in-shell hazelnuts into the United States?Common documents include a commercial invoice, packing list, bill of lading/air waybill, and CBP entry documentation; FDA Prior Notice may apply because the product is food, and additional documentation may be needed based on shipment specifics.
