8474.90.00.20 - Of crushing or grinding machines 🖩

This HTS category, 8474.90.00.20, specifically covers parts and accessories for machinery designed for crushing or grinding mineral substances. This includes components such as crushing jaws, grinding balls, hammers for impact crushers, rollers, and screens that are integral to the pulverization or reduction of solid materials like stone, ores, and earth. The primary function of the parent machinery is the reduction of particle size through mechanical force.

It is crucial to distinguish this category from its siblings. For instance, HTS 8474.90.00.10 pertains to parts for sorting, screening, separating, or washing machines, which perform different functions that do not involve size reduction. Similarly, HTS 8474.90.00.50 covers parts for mixing or kneading machines, focusing on combining or homogenizing materials rather than breaking them down. When classifying parts, the principal function of the complete machine with which the part is intended to be used is the determining factor.

As this is a leaf node, there are no further subdivisions under this specific HTS code. Therefore, classification within 8474.90.00.20 relies on identifying that the part's design and purpose are exclusively for crushing or grinding operations within the scope of heading 8474. Examples of materials commonly processed by machines utilizing these parts include coal, cement clinker, aggregate, and various minerals.
