Cashew Grades Explained: W180, W240, W320, W450

Cashew Grades Explained: W180, W240, W320 and W450 Cashew kernels are graded by size, and this grading system determines both price and how buyers use the product. For importers, distributors and food manufacturers, understanding the difference between W180, W240, W320 and W450 is essential before placing an order. This guide breaks down what each grade means, how kernels are counted and graded, and how to match the right grade to your business needs. What Does the "W" Grade Actually Mean The "W" stands for "whole," indicating unbroken cashew kernels, and the number that follows shows how many kernels make up one pound (454 grams) of product. A lower number means fewer, larger kernels per pound, while a higher number means more, smaller kernels per pound. For example, W180 kernels are large enough that only about 180 of them weigh one pound, while W450 kernels are smaller, so it takes roughly 450 of them to reach the same weight. Kernel size does not necessarily reflect flavor or nutritional value, but it strongly affects price and how the product is used commercially. Cashew Grading Standards and Kernel Count Cashew grading follows counts per pound, and the accepted range for each grade typically falls within these limits. These size classes are formally recognized in the UNECE Standard DDP-17 for Cashew Kernels and detailed further in the International Nut and Dried Fruit Council's cashew industry standards : Grade Kernels per Pound Kernel Size Typical Use W180 150 to 180 Very large, premium Gift packs, premium snacking, retail display W210 190 to 210 Large Premium retail and snack mixes W240 220 to 240 Medium-large Retail packaging, snacking, export markets W320 300 to 320 Medium, most common Food processing, bakery, confectionery, general trade W450 400 to 450 Small whole kernels Bakery inclusions, cooking, industrial use These counts can vary slightly depending on the certification body or the buyer's country of import, so specifications should always be confir
