Raw Cashew Nut (RCN) Outturn Analysis: The Complete Guide to 50–55 LBS+
A deep-dive technical manual on how Kernel Output Ratio (KOR) is measured, calculated, and guaranteed in Tanzanian RCN export contracts.
Key Commercial Takeaways for Buyers
- ✓Outturn represents the usable kernel weight in pounds obtained from an 80 kg bag of raw nuts.
- ✓Tanzanian cashews consistently achieve 50–55 LBS+, placing them among the top tier worldwide.
- ✓Proper 1 kg cutting tests verify kernel recovery, shell thickness, and defective nut percentages.
In the international cashew trade, the single most critical contract metric is Kernel Output Ratio (KOR), commonly referred to as "Outturn" expressed in pounds (LBS) per 80 kg jute bag.
Calculating Outturn: The Standard Cutting Test: A standard 1 kilogram sample is randomly drawn from multiple bags across the lot. The nuts are counted to determine Nut Count per KG (ideal: 160–180 nuts/kg). Each nut is then cracked along its natural seam, and kernels are segregated into: - Good, clean kernels (W1): Multiplied by full weight. - Spotted / slightly defective kernels (W2): Multiplied by 50% weight. - Rotten or void nuts (W3): Completely rejected (0%).
Formula: Total Usable Kernel Weight (Grams) × 80 kg ÷ 453.59 = Outturn in LBS.
Why Tanzania Outperforms Competitors: While West African RCN often tests between 44–48 LBS, Tanzanian nuts harvested in Mtwara, Lindi, and Ruvuma regularly achieve 50 to 55 LBS+. The higher outturn means processors yield up to 15% more whole white kernels (W180, W240, W320), drastically boosting processing profitability.
