Cashews have one of the widest ranges of sizes and qualities within the nuts category, and understanding these differences is important for B2B buyers. It helps to decide how the cashews look, their size, and how they will be used, priced, and sold.
Cashew grades are standards that sort cashew nuts by size, color, shape, and quality. These grades help buyers and suppliers communicate clearly during trading. They make sure that the product meets expectations in appearance and performance.
Cashew grading follows international standards, primarily set by organizations like the Cashew Export Promotion Council of India (CEPCI) and the Vietnam Cashew Association (VINACAS). The cashew quality is based on a few factors, such as: Size, Color, Shape, and Defects.

Whole cashew kernels are classified into different grades based on size and color. Below you can find the most common cashew sizes:
Scorched Whole Cashews (SW180, SW210, SW240, SW320, etc.) refer to cashews that are slightly browned during roasting, typically due to higher temperatures during processing. While SW cashews are cheaper, they retain their nutritional value and are widely used in cooking and processed food applications.
Broken cashew grades are used in nut butters, confectionery, bakery products, and food processing where whole nuts are not required. These include:
Broken cashew nuts are more affordable and offer cost-effective solutions for large-scale food manufacturers.
Dessert cashew nuts include cashews that do not meet the cashew standards for whole or premium broken grades but are still suitable for desserts, food coatings, and ingredient blends. These include:
Dessert cashew nuts provide an economical alternative for food businesses looking for cashews suitable for mass-market baked goods and confectionery applications.
Different regions specialize in processing specific cashew grades:
When choosing a cashew grade, businesses should consider:
Sourcing from trusted cashew nuts suppliers ensures product quality and compliance with international standards.
When you buy cashew kernels graded W320 from a Vietnamese supplier, you are almost certainly buying West African raw cashew nuts that were shipped to Vietnam for processing. Understanding this distinction is one of the most practically useful things a buyer can know about the cashew supply chain.
Cashew trees grow in tropical climates, and the producing countries are concentrated in West Africa, Southeast Asia, and India. West Africa is by far the dominant growing region, with the Ivory Coast, Tanzania, Mozambique, Guinea-Bissau, and Benin collectively producing approximately 50-55% of the total global raw cashew nut supply. India produces a further 20-25%, and Vietnam grows only a small fraction of what it processes.
| Country | Role in supply chain | Notes for EU buyers |
| Ivory Coast | Largest RCN producer (~25% global) | Significant EU export; EU-certified processors increasing |
| Tanzania | Major East African RCN producer | Traceability credentials improving; some certified EU-ready processors |
| Vietnam | World's largest cashew processor (~65% of global kernels) | Processes predominantly African RCN; most W-grade kernels shipped to EU originate here |
| India | Both a producer and a large processor | Large domestic consumption; W-grades exported; strong IFS/BRC presence |
| Brazil | Smaller producer and exporter | Higher price; traceable single-origin product; preferred for premium/organic sourcing |
When a supplier quotes "Vietnamese cashews W320", they are describing the country where the kernel was processed and graded, not where the tree grew. The raw nut was most likely harvested in West Africa, dried, shipped to a Vietnamese processing facility, shelled, graded, and packed for export. This is not a quality issue (Vietnamese processing facilities have excellent equipment and hygiene standards) but it has two practical implications.
First, price: Vietnamese W-grade kernels are competitively priced because Vietnam's processing scale creates efficiency. When you compare a Vietnamese W320 quote with an Indian W320 quote, you are comparing similar products from different processing countries, often using the same African RCN. If the price gap is significant, ask whether the difference is in the RCN origin, the processing grade, or just the trader's margin.
Second, traceability: if your product specification or retailer requires plantation-level traceability (increasingly common for sustainability-positioned products), "processed in Vietnam" is not sufficient. You need your supplier to provide RCN origin documentation. Not all processors can or will provide this. Suppliers who offer traceable RCN origin (typically Tanzanian or Brazilian single-origin cashews) ask a higher price but satisfy retailer requirements that Vietnamese-processed African RCN cannot.
Aflatoxin risk in cashews varies more by harvest handling and drying conditions than by growing country, but origin does signal risk level. West African RCN harvested in areas with high post-harvest humidity (particularly in rainy season crop) carries higher aflatoxin risk than Indian or Brazilian RCN dried under more controlled conditions. Vietnamese processors who source from multiple African origins manage this risk through incoming RCN testing. We advise you to always ask your supplier for incoming RCN CoA data as well as finished-product testing.
Moisture content in finished cashew kernels should not exceed 5% (USDA specification; EU buyers typically require 4.5% maximum). Kernels with higher moisture are susceptible to mould growth in transit, particularly in container shipments during humid summer months. Request moisture analysis on the finished kernel CoA, not just the grade certificate.
In practice, the highest risk moment for cashew quality is not the growing or processing stage, it is the container transit from Asia to Europe. A 20-foot dry container of cashews can develop internal condensation during passage through the Red Sea or Suez Canal in summer. Buyers who specify desiccant packs inside the container and who request container temperature logging (available from specialist freight insurers) have significantly fewer quality claims than those who do not.
