Premium Wholesale Inshell Walnuts (Walnuts in Shell) – High Meat Yield Bulk Supplier
Our farm-direct Inshell Walnuts (Juglans regia) are harvested from premier high-altitude agricultural zones featuring long sunshine hours, large diurnal temperature gaps, and mineral-rich snowmelt irrigation. Through automated air-cleaning, water washing, precise low-temperature drying, and mechanical size calibration, our walnuts in shell offer exceptionally clean golden-tan exteriors, thin paper-like shells, high kernel yields (≥50%), and bright extra-light kernels. They are ideal for international retail snack packaging, seasonal gift markets, and commercial cracking operations.
Why Partner with Us for Wholesale Inshell Walnuts?
- Superior Thin-Shell Varieties: Featuring Xinjiang 185 Thin Shell and Xiangling varieties, famous for easy hand-cracking without shell crushers.
- High Meat Yield Ratio (≥50%): Exceptionally plump internal kernels offering maximum edible weight per ton compared to standard thick-shell varieties.
- Strict Mechanical Caliber Sizing: Accurate sorting across 28mm+, 30mm+, 32mm+, 34mm+, and 36mm+ diameters ensures uniform container packing.
- Export Safety Certification: Fully certified under BRCGS, ISO22000, HACCP, USDA Organic, Halal, and Kosher quality standards.
Nutritional Integrity & Product Superiority
Leaving walnuts in their natural protective shell preserves their essential oils, volatile aromas, and nutritional potency far longer than shelled kernels. Fresh Juglans regia inshell nuts deliver outstanding bio-nutritional benefits:
- Natural Oxidation Barrier: The hard outer shell provides a natural protective barrier against ambient oxygen, light, and humidity, preserving kernel crispness.
- Rich Essential Omega-3 (ALA): Delivers natural plant-based Alpha-Linolenic Acid, supporting neurological health and cellular integrity.
- Potent Antioxidants & Minerals: Abundant polyphenols, tocopherols, magnesium, and copper assist in cardiovascular maintenance.
- Longer Shelf Life Stability: Inshell walnuts withstand ambient transport better than shelled kernels, minimizing FFA elevation risks during ocean shipping.

Packaging Options, Storage & International Logistics
Inshell walnuts require proper ventilation during ocean transport to prevent moisture buildup and outer shell discoloration:
- Standard Bulk Export Packaging: 10 kg, 20 kg, or 25 kg polypropylene (PP) woven bags, or high-breathability mesh bags loaded into dry 40ft High Cube containers.
- OEM Private Label Packaging: Custom printed retail bags (500g, 1kg, 2.5kg) or burlap gift sacks available upon customer artwork specification.
- Warehouse Storage Requirements: Store in a cool, dry, and well-ventilated warehouse ($0\text{–}10^\circ\text{C}$, relative humidity $<60\%$). Avoid direct ground contact and unventilated humid enclosures.
- Global Export Shipping: Rapid shipment from major ports (Tianjin, Qingdao, or Lianyungang) complete with Phytosanitary Certificates, Fumigation Certificates, Health Certificates, and Certificate of Origin.
Frequently Asked Questions (FAQ)
Q1: What is the meat yield (crack-out rate) of your 185 paper shell inshell walnuts?
Our Xinjiang 185 Paper Shell inshell walnuts yield an average crack-out rate of 50% to 54%. This means that over half of the total weight purchased consists of edible, high-value kernel meat, significantly higher than traditional thick-shell varieties that yield only 40–43%.
Q2: Are your inshell walnuts chemically bleached or natural washed?
We prioritize food safety and offer 100% naturally air-washed and water-cleaned unbleached inshell walnuts compliant with strict EU organic and pesticide residue standards. Lightly bleached or food-grade hydrogen peroxide washed options are also available upon request for markets that require extra-bright shell surfaces.
Q3: How do you prevent mold growth during long-distance ocean container shipments?
We strictly dehydrate the inshell walnuts down to a safe moisture content below 8.0% prior to bagging. During container stuffing, we utilize breathable PP woven/mesh bags, place industrial moisture-absorption desiccant bags inside the container, and perform professional container fumigation.
Q4: What is your Minimum Order Quantity (MOQ) and container loading capacity?
Our minimum order quantity for standard bulk woven bags is 5 Metric Tons. For maximum freight efficiency, a standard 40ft High Cube container loads approximately 20 to 22 Metric Tons depending on bag configuration and caliber size. Complimentary physical samples (1kg–2kg) are available for prospective buyers (buyer covers express courier freight).
