Understanding Cashew Kernel Grades: W180 to WS Explained

Why Grades Matter

Cashew kernel grading is the international language of cashew trade. A buyer in Amsterdam and a processor in Kollam both use the same grading nomenclature, which makes it the foundation of every commercial transaction.

The W-Grade System (White Wholes)

W-grades describe whole white cashew kernels. The number represents the count of kernels per pound:

Splits, Butts, and Pieces

WS (Splits) are whole kernels broken lengthwise into two halves. They trade at a 30–40% discount to the corresponding whole grade but have strong demand from confectionery manufacturers and bakeries who do not require visual whole kernels.

WB (Butts) and Pieces (SP, LP) are used in processed foods, nut butters, and flavouring. They represent significant volume in the global trade.

Colour Grades

Beyond size, kernels are also graded by colour: White (W), Scorched (S), and Desert (D). White grades command the highest premiums. Scorched kernels result from over-processing and typically trade at 15–25% discount.
