Cashews are not simply classified by whether they look big, small, white, or broken. In the cashew industry, grading is a systematic way of classifying kernels based on their size, count, shape, wholeness, appearance, and quality characteristics.

For wholesalers, retailers, food manufacturers, hotels, restaurants, snack companies, and exporters, understanding cashew grades is important because the right grade can directly influence product appearance, application, yield, customer expectations, and overall cost.

In this guide, we explain what cashew grades mean, how they are determined, the differences between popular grades, and how businesses can select the right grade for their requirements.

 

What Are Cashew Grades?

A cashew grade is a classification given to cashew kernels according to defined physical and quality characteristics.

One of the most commonly used grading systems for whole cashew kernels uses codes such as:

• W180
• W210
• W240
• W320
• W450

Here, “W” generally stands for Whole, while the number represents the approximate number of kernels per pound in the traditional count-based grading system.

For example, W180 represents a larger whole-kernel grade, while W320 represents a smaller whole-kernel grade.

This means that, generally:

Lower number = larger kernel
Higher number = smaller kernel

However, grade is not determined by size alone. Factors such as kernel integrity, colour, defects, appearance, moisture, processing quality, and sorting also matter when evaluating commercial quality.

 

How Are Cashew Grades Determined?

Cashew grading starts after the kernels have gone through the necessary processing and quality-control stages.

A typical process may include:

Raw Cashew Procurement → Washing → Sorting → Boiling/Steam Processing → Cutting → Kernel Recovery → Drying/Borma → Peeling → Colour Sorting → Grading → Manual Inspection → Packaging

During grading and quality inspection, kernels are evaluated according to several characteristics.

1. Size and Kernel Count

Size is one of the most important factors in determining a whole-kernel grade.

In traditional count-based grading, the number indicates the approximate number of kernels per pound.

Therefore, larger kernels have a lower count.

For example:

W180 → Larger kernels
W210 → Large kernels
W240 → Medium-large kernels
W320 → Medium-sized kernels
W450 → Smaller kernels

The exact commercial specifications can vary depending on the applicable standard, market, origin, and buyer specification.

 

2. Whole or Broken Kernel

The physical integrity of the kernel is another important classification factor.

Whole kernels retain their complete shape, while broken kernels are classified separately.

Common categories may include:

• Whole kernels
• Splits
• Large pieces
• Small pieces
• Baby bits

Whole kernels generally command a different price because they offer better visual presentation and are suitable for applications where appearance matters.

 

3. Colour and Appearance

Cashew kernels can differ in colour and appearance.

Depending on the grade and quality specification, buyers may look for kernels that are:

• White or pale
• Uniform in colour
• Clean-looking
• Free from excessive discoloration
• Free from visible mould or foreign matter

Colour is particularly important for premium retail packs, gifting products, bakery applications, and products where the cashew is visibly presented.

 

4. Surface Quality and Defects

The surface of the kernel is examined for defects such as:

• Spots
• Discolouration
• Insect damage
• Shrivelling
• Mechanical damage
• Excessive scorching
• Foreign matter

The acceptable level of defects depends on the applicable grade and buyer specification.

 

5. Moisture

Moisture is an important quality and storage parameter.

Proper moisture management helps maintain the desired texture and shelf stability of cashew kernels and reduces the risk of quality deterioration during storage.

Moisture is therefore controlled during processing, drying and storage, rather than being considered only at the final grading stage.

 

Understanding Popular Cashew Grades

Let’s look at some of the most commonly traded cashew grades.

1. W180 – Extra Large Whole Cashews

W180 is commonly associated with very large whole cashew kernels.

Characteristics:

• Very large kernel size
• Whole kernel
• Premium visual appearance
• Limited number of kernels per pound compared with smaller grades
• Often positioned toward premium applications

Common Applications:

• Premium retail packs
• Gift boxes
• Premium snack products
• Luxury food presentations
• High-end hospitality

Because of their larger size and visual appeal, W180 kernels are generally positioned at the premium end of the whole-kernel range.

 

2. W210 – Large Whole Cashews

W210 is another large whole-kernel grade.

Characteristics:

• Large kernel size
• Whole kernel
• Attractive appearance
• Suitable for premium and general snacking applications

Common Applications:

• Premium snacks
• Retail packs
• Hotels and restaurants
• Gifting
• Food service

W210 can be a practical option for businesses looking for a large, premium-looking kernel without necessarily selecting the largest available grade.

 

3. W240 – Medium-Large Whole Cashews

W240 is one of the widely traded whole-kernel grades.

Characteristics:

• Medium-large kernel
• Whole kernel
• Good visual appeal
• Versatile for multiple applications

Common Applications:

• Retail
• Snacking
• Restaurants
• Hotels
• Bakeries
• Food manufacturing

Its combination of size, appearance and commercial practicality makes W240 suitable for a broad range of applications.

 

4. W320 – Standard Whole Cashew Grade

W320 is one of the most widely traded whole-kernel cashew grades globally.

Characteristics:

• Medium-sized whole kernels
• Good appearance
• Versatile application
• Generally more commercially accessible than larger premium grades

Common Applications:

• Retail packs
• Roasted and salted cashews
• Snacks
• Bakeries
• Sweets and confectionery
• Hotels and restaurants
• Food manufacturing

For many businesses, W320 provides a useful balance between appearance, usability and cost.

 

5. W400 – Smaller Whole Cashews

W450 is generally a smaller whole-kernel grade compared with W320.

Characteristics:

• Smaller whole kernels
• Whole shape
• Suitable for applications where very large kernels are not essential

Common Applications:

• Snacks
• Food processing
• Bakery
• Confectionery
• Institutional and food-service applications

W450 can be useful when a business wants whole kernels but does not require the larger visual presentation associated with W180 or W210.

 

6. SW320 – Scorched Wholes

SW grades are commonly used for scorched whole kernels.

SW320 therefore refers to a whole-kernel category with a darker/scorched appearance compared with standard white whole grades, subject to the applicable quality specification.

Common Applications:

• Roasted products
• Snack mixes
• Food processing
• Applications where colour is less critical

The key difference here is that the classification is not simply about kernel size. Colour and appearance characteristics are also part of the classification.

 

7. SW240 – Scorched Large Wholes

SW240 represents a larger whole-kernel category within the scorched-whole classification.

Characteristics:

• Whole kernel
• Larger size category
• Scorched/darker appearance
• Suitable for applications where the appearance specification permits it

Common Applications:

• Roasted snacks
• Food processing
• Commercial snack mixes
• Certain bakery and confectionery applications

 

8. Cashew Pieces – LWP and Other Piece Grades

Not every cashew kernel needs to be sold as a whole kernel.

During processing, some kernels naturally break or are separated into pieces. These can be classified into different piece grades depending on their size.

Examples include:

• LWP – Large White Pieces
• SWP – Small White Pieces
• BB – Baby Bits
• Other commercially defined piece categories

Common Applications:

• Bakery
• Chocolate
• Desserts
• Ice cream
• Sweets
• Cashew paste
• Food manufacturing
• Toppings and inclusions

For many food manufacturers, pieces can be a highly practical choice because the product does not require the visual appearance of a whole kernel.

Important: Commercial specifications, tolerances, count ranges and grade nomenclature can vary by origin, supplier, market and buyer specification. A professional buyer should always confirm the exact specification before placing an order.

 

What Is the Difference Between Cashew Grades?

The biggest differences between cashew grades can be understood through five major parameters:

1. Size

The physical size of the kernel is a major factor in whole-kernel grading.

2. Count

In traditional count-based grading, the number of kernels per pound helps identify the size category.

3. Whole vs Pieces

Whole kernels and broken pieces are classified differently because their applications and commercial values can differ.

4. Colour and Appearance

White, pale, scorched or differently coloured kernels may fall into different commercial categories depending on the applicable specification.

5. Defects and Quality

The presence and level of defects, damage, foreign matter, moisture and other quality parameters influence whether a particular lot meets a buyer’s specification.

Therefore, two cashews can look similar in size but still differ in commercial quality because of differences in colour, defects, processing, moisture or other quality parameters.

 

How Is Cashew Quality Determined Beyond the Grade?

A common mistake is to assume:

“Higher grade = better cashew for every business.”

That is not necessarily true.

Grade primarily helps communicate the physical characteristics of the kernel. But a business should evaluate the complete quality profile of the product.

Important quality checks include:

Smoothness

The kernel should have a clean and appropriate surface for its intended grade.

Texture

The kernel should have the expected firmness and bite, without undesirable softness, excessive shrivelling or other quality defects.

Colour

Colour uniformity and the acceptable level of discoloration should match the buyer’s specification.

Aroma and Taste

Cashews should have the characteristic fresh cashew aroma and flavour and should be free from undesirable odours or flavours.

Moisture

Moisture should be controlled within the applicable specification to support quality and storage stability.

Foreign Matter

The product should be appropriately cleaned and protected from foreign material.

Defects

The lot should be inspected for defects such as insect damage, mould, excessive discoloration, mechanical damage and other unacceptable characteristics.

 

Why Does Cashew Manufacturing Matter?

The quality of the finished cashew does not depend only on the grading machine.

It starts much earlier—with raw cashew selection and processing discipline.

A professional cashew manufacturing process can involve:

Raw Cashew Selection → Washing → Sorting → Boiling/Steam Processing → Cutting → Kernel Recovery → Drying/Borma → Peeling → Colour Sorting → Grading → Manual Inspection → Packaging

Each stage can influence the final product.

For example, proper raw material selection can contribute to better kernel recovery and consistency. Controlled processing can help reduce unnecessary damage. Effective drying can help manage moisture. Colour sorting and manual inspection can help remove unsuitable kernels.

This is why grade and manufacturing quality should be evaluated together.

 

Safety and Hygiene: An Essential Part of Cashew Quality

A visually attractive cashew is not enough.

For commercial buyers, especially food manufacturers and retailers, food safety and hygiene should be an essential part of supplier evaluation.

A professional processing facility should have appropriate controls for:

• Hygienic processing areas
• Personnel hygiene
• Cleaning and sanitation
• Pest-control practices
• Foreign-matter prevention
• Proper storage
• Traceability
• Quality inspection
• Appropriate packaging and handling

The exact certifications and controls required will depend on the market, customer and applicable regulations.

Therefore, when purchasing cashews, don’t evaluate only the grade printed on the quotation. Evaluate the product, the process and the supplier together.

 

How to Choose the Best Cashew Grade for Your Business

There is no single cashew grade that is the right choice for every business.

The best grade depends on what you are selling, how the cashew will be used, what your customers expect and what price point you are targeting.

For Premium Retail and Gifting

Consider larger whole-kernel grades such as:

W180 / W210

These grades can provide a strong visual presentation where kernel size is an important part of the product experience.

For General Retail and Snacking

Grades such as:

W240 / W320

can be considered depending on the target market, pack positioning and price point.

For Food Manufacturing

If the cashew will be chopped, blended, incorporated into another product or used as an ingredient, whole premium kernels may not always be necessary.

LWP and other suitable piece grades can be evaluated depending on the manufacturing application.

For Roasted Products

Scorched-whole grades such as:

SW240 / SW320

may be suitable for applications where their appearance fits the finished product.

 

A Simple Checklist for Buying Cashews

Before purchasing, don’t ask only:

“Which grade is this?”

Ask these questions too:

Product

• What is the exact grade?
• What is the kernel size/count?
• Is it whole or broken?
• What is the colour specification?
• What are the permitted defects?

Quality

• What is the moisture specification?
• How is the product inspected?
• Is colour sorting carried out?
• Is manual inspection carried out?
• How is the product stored?

Manufacturing

• Where is the cashew processed?
• What processing controls are followed?
• What hygiene practices are maintained?
• How is foreign matter controlled?
• Is the product properly packed for transportation and storage?

Business

• What is the intended application?
• What price point are you targeting?
• What appearance does your customer expect?
• Do you really need a premium whole grade?
• Would a suitable piece grade provide better economics for your application?

 

Final Thoughts

Understanding cashew grades is the first step toward making better purchasing decisions.

A grade such as W180, W210, W240, W320 or W450 gives you an important indication of the kernel category, particularly size and whole-kernel characteristics. However, grade alone does not tell the complete story of cashew quality.

The right buying decision should consider:

Size + Count + Whole/Pieces + Colour + Smoothness + Texture + Defects + Moisture + Processing + Hygiene + Packaging + Application

Ultimately, the best cashew for your business is not necessarily the biggest or most expensive one.

It is the one that delivers the right combination of appearance, quality, consistency, food safety, application suitability and commercial value.

At NutFresh, our approach to cashews goes beyond simply assigning a grade. From raw cashew selection and controlled processing to sorting, grading, inspection and packaging, every stage plays a role in delivering consistent quality for our B2B customers.

Because great cashews are not just about the grade—they are about the quality behind the grade.
