8474.10.00 - Sorting, screening, separating or washing machines

This HTS category, 8474.10.00, encompasses machinery specifically designed for the initial processing of solid mineral substances, including earth, stone, and ores. These machines are utilized to segregate materials based on size, density, or other physical characteristics through processes of sorting, screening, separating, or washing. Examples include vibratory screens for separating materials by size, jigs and cyclones for density-based separation, and washing machines for removing impurities from aggregates or ores.

Unlike sibling categories within 8474, such as crushing and grinding machines (8474.20.00) or mixing and kneading machines (8474.30.00), the primary function here is not size reduction or amalgamation, but rather the initial stage of material refinement through physical separation and purification. Similarly, it is distinct from "other machinery" (8474.80.00), which covers less specialized or unique mineral processing equipment not fitting other specific subheadings.

Within this category, further distinctions are made between portable and stationary units. Subcategory 8474.10.00.10 covers machinery designed for ease of movement and on-site application, while 8474.10.00.90 classifies those machines intended for fixed installation within a processing plant. This distinction is crucial for accurately reflecting the operational deployment and intended use of the equipment.
