Cashew Grading Standards

Understanding cashew grading is essential for anyone involved in buying, selling, exporting, or processing cashew kernels.

International grading standards provide a common language that allows producers, exporters, importers, and food manufacturers to communicate product quality consistently across global markets.

Whether you are purchasing premium whole kernels for retail packaging or selecting ingredients for food manufacturing, understanding the grading system helps you choose the right product for your needs.

Quick Facts

  • Cashew kernels are graded after shelling, peeling, drying, and quality inspection.
  • Grades are determined by color, shape, size, and quality.
  • The grade number represents the approximate number of kernels per pound.
  • Lower grade numbers generally indicate larger kernels.
  • WW320 is one of the most widely traded export grades worldwide.

Why Cashew Grading Matters

Cashew grading creates a standardized system that ensures buyers and sellers have the same expectations regarding kernel quality.

Without international grading standards, every exporter could describe products differently, making global trade inefficient and inconsistent.

A standardized grading system helps:

  • Maintain consistent product quality
  • Simplify international trade
  • Support fair pricing
  • Reduce misunderstandings between buyers and suppliers
  • Improve food quality assurance

It also enables buyers to compare products from different suppliers using the same internationally recognized grading terminology.

How Cashew Grading Works

International cashew grading follows a structured classification system that describes each kernel using three key characteristics:

  1. Color
  2. Shape
  3. Size

Together, these characteristics form the grade code used throughout the global cashew industry.

Understanding Grade Codes

Every cashew grade is a combination of:

Color + Shape + Size

For example:

WW320 = White + Whole + 300–320 kernels per pound

1. Color Classification

Color indicates the visual appearance of the kernel after processing.

The three most common classifications are:

CodeMeaning
WW180140–180Largest premium kernels
WW210180–210Large premium kernels
WW240220–240Premium retail grade
WW320300–320Most common export grade
WW450400–450Cost-effective whole kernels
WW500450–500Small whole kernels

White kernels are considered the premium appearance, while scorched kernels have a slightly darker color caused during processing. Dessert grades include kernels with more noticeable color variations but remain suitable for many food applications.

2. Shape Classification

Shape describes the physical condition of the kernel after shelling and peeling.

CodeMeaning
WWhole
BButts
SSplits
PPieces

Whole kernels command the highest value because they have the best appearance, while splits and pieces are widely used in food manufacturing and ingredient processing.

3. Size Classification

Whole kernels are further classified according to the approximate number of kernels per pound (454 g).

A lower number means a larger kernel.

For example:

  • WW180 → Approximately 140–180 kernels per pound
  • WW210 → Approximately 180–210 kernels per pound
  • WW240 → Approximately 220–240 kernels per pound
  • WW320 → Approximately 300–320 kernels per pound
  • WW450 → Approximately 400–450 kernels per pound Larger kernels are generally considered more premium because of their appearance and lower natural yield.

Whole White (WW) Grades

Whole White (WW) grades represent premium cashew kernels that are whole, clean, and light in color. They are the most recognized grades in international trade and are widely used for retail packaging, premium snacks, and export markets.

The number following WW indicates the approximate number of kernels per pound (454 g). In general, a lower number means a larger kernel.

GradeKernels per PoundTypical Position
WW180140–180Largest premium kernels
WW210180–210Large premium kernels
WW240220–240Premium retail grade
WW320300–320Most common export grade
WW450400–450Cost-effective whole kernels
WW500450–500Small whole kernels

Understanding Kernel Size

The grade number does not represent quality.

Instead, it indicates the approximate number of whole kernels per pound.

For example:

  • WW180 contains fewer but larger kernels.
  • WW320 contains more but smaller kernels.

Both grades can meet high international quality standards.

Choosing the Right Grade

Different buyers select different grades depending on their products and target markets.

Buyer TypeCommonly Selected Grades
Premium Gift ProductsWW180, WW210
Retail BrandsWW240, WW320
Snack ManufacturersWW320, WW450
Food ManufacturersSplits, Pieces

The most suitable grade depends on product appearance, packaging requirements, customer expectations, and budget rather than on quality alone.

Other Cashew Grades

While Whole White (WW) grades are the most recognized in international trade, several other grades are widely used depending on processing quality and intended applications.

Scorched Grades (SW)

Scorched kernels have a slightly darker appearance than White grades due to heat exposure during processing or natural color variation. Despite the darker color, they remain safe to eat and are widely accepted for many commercial applications.

Common scorched grades include:

GradeDescriptionTypical Applications
SWScorched WholeRetail products, snacks, food service
SSWSecond Scorched WholeIngredient processing, food manufacturing

Important Note

Scorched kernels are not spoiled. The term “scorched” refers only to their appearance and does not necessarily indicate poor eating quality.

Pieces Grades

Not every kernel remains whole during processing. Broken kernels are carefully sorted into different grades according to their size and shape.

Common pieces grades include:

GradeMeaningTypical Applications
LPLarge PiecesPremium bakery products
SPSmall PiecesConfectionery and snacks
BBBaby BitsIce cream, cereals, bakery
LWPLarge White PiecesFood manufacturing

Pieces grades provide excellent value for manufacturers because they maintain the same flavor and nutritional value as whole kernels while offering a more economical option.


Quality Factors

International buyers evaluate cashew kernels using several quality characteristics beyond size alone.

The most important quality factors include:

  • Uniform color
  • Whole kernel shape
  • Proper moisture content
  • Low defect levels
  • Clean appearance
  • No foreign matter
  • No unusual odor

Quality vs. Size

A larger kernel is not automatically a higher-quality kernel.

Quality is determined by compliance with grading standards, while size simply indicates the approximate number of kernels per pound.


Grade Comparison

GradeAppearanceTypical Use
WW180Large whole white kernelsPremium gifts and luxury retail
WW210Large whole white kernelsPremium retail
WW240Medium-large whole kernelsRetail packaging
WW320Medium whole kernelsGeneral export and snacks
WW450Smaller whole kernelsCost-effective retail
SWSlightly darker whole kernelsFood service and snacks
LPLarge kernel piecesBakery
SPSmall kernel piecesIngredients
BBSmall broken piecesIndustrial food production

The best grade depends on your product requirements, target customers, packaging style, and budget rather than on kernel size alone.

Key Takeaways

Understanding cashew grading helps buyers, exporters, and consumers make informed purchasing decisions.

The most important points to remember are:

  • Cashew grades are determined by color, shape, size, and quality.
  • The grade number represents the approximate number of kernels per pound.
  • Lower grade numbers indicate larger kernels, not necessarily higher quality.
  • Whole White (WW) grades are the most common premium export grades.
  • Splits and pieces provide excellent value for food manufacturing and ingredient applications.
  • Buyers should choose grades based on their intended application rather than size alone.
