6804.10.00.00 - Millstones and grindstones for milling, grinding or pulping

HTS Code 6804.10.00.00 specifically enumerates millstones and grindstones intended for milling, grinding, or pulping operations. These items are designed for the bulk reduction of materials, such as grains, spices, or minerals, and are typically characterized by their substantial size and abrasive surfaces. The key distinguishing feature of this category is its explicit focus on stones used for processing or breaking down substances.

This classification is differentiated from its sibling categories by its exclusive focus on milling and grinding applications. HTS 6804.21.00.00, for example, covers "Other millstones, grindstones, grinding wheels and the like," which are generally used for sharpening, polishing, trueing, or cutting. Similarly, HTS 6804.30.00.00 pertains to "Hand sharpening or polishing stones," indicating smaller, portable abrasives for manual use rather than industrial material processing.

As a leaf node within the HTS structure, HTS 6804.10.00.00 does not have further subdivisions. Therefore, classification within this code relies on identifying articles that are primarily millstones or grindstones designed for the purpose of milling, grinding, or pulping, irrespective of whether they are made from natural stone, agglomerated natural or artificial abrasives, or ceramics, and whether or not they include parts of other materials. The intended use for bulk material reduction is the paramount criterion for classification.
