8474.90.00.10 - Of sorting, screening, separating or washing machines

This HTS category, 8474.90.00.10, encompasses parts specifically designed for machinery used in the sorting, screening, separating, or washing of earth, stone, ores, and other solid mineral substances. This includes components for equipment that, for example, segregates materials by size through sieving, removes impurities through washing, or divides mixed substances into distinct streams. The primary function of these parts is to facilitate the physical division or purification of solid mineral materials.

It is crucial to distinguish this category from its siblings. Parts classified under 8474.90.00.20 are exclusively for crushing or grinding machines, which reduce the size of mineral substances. Similarly, 8474.90.00.50 covers parts for mixing or kneading machines, where the objective is to combine or homogenize materials, not to separate them. If a part does not serve the specific functions of sorting, screening, separating, or washing, and is not for crushing, grinding, mixing, or kneading, it would likely fall under the residual "Other" category, 8474.90.00.90.

As this node is a leaf node within the HTS, there are no further subcategories to detail. Therefore, classification into 8474.90.00.10 relies entirely on the definitive purpose of the part in relation to sorting, screening, separating, or washing machinery within the scope of heading 8474. The material composition of the part itself is secondary to its intended function within these specific types of mineral processing machinery.
