France's Périgord and Grenoble regions produce cold-pressed walnut oil with Appellation d'Origine Protégée (AOP) status, harvested September to November. California produces the majority of US walnuts with harvest September to November, where walnut oil is pressed from lower-grade kernels unsuitable for whole nut export. Walnuts are a mandatory tree nut allergen under Regulation (EU) No 1169/2011, requiring walnut oil products to carry allergen labelling regardless of refining degree. China represents a growing source for volume supply, though quality specifications vary significantly between regions.
Walnut oil is highly oxidation-sensitive due to its polyunsaturated fat content and requires nitrogen-flushed packaging in dark containers. Storage below 15 degrees Celsius extends shelf life to 12 months, while room temperature storage reduces this to 6-8 months maximum. Buyers must verify free fatty acid levels not exceeding 1% and confirm the smoke point of approximately 160 degrees Celsius makes it unsuitable for high-heat cooking applications. Hazelnut oil and pumpkin oil suppliers often carry walnut oil as part of their specialty finishing oil range.
EU Organic and USDA NOP certified walnut oil is available from French AOP regions and California orchards. French organic walnut oil carries higher pricing due to limited harvest volumes and AOP designation requirements. Almond oil suppliers frequently offer both tree nut oils under identical organic certification schemes, sharing processing infrastructure and allergen management protocols.
Private label formats include 250ml to 500ml dark glass bottles for gourmet retail, 50ml to 100ml bottles for cosmetic lines, and softgel capsules for omega-3 supplements. MOQs typically start at 1,000 units for bottled oils and 5,000 units for capsule formats. Buyers must specify whether the end product targets culinary or cosmetic use, as this determines labelling requirements and shelf life expectations.
Manufacturers concentrate in France's Dordogne region for AOP production and California's Central Valley for volume supply. Documentation to request includes batch-specific certificates of analysis, omega-3 fatty acid profiles, and allergen management protocols demonstrating tree nut segregation.
