8464.90.01 - Other

This HTS category, 8464.90.01, encompasses "Other" machinery and mechanical appliances designed for working stone, ceramics, concrete, asbestos-cement, or similar mineral materials, as well as for the cold working of glass. It serves as a residual category for machines falling within Chapter 84 that are not specifically enumerated under the sawing, grinding, or polishing machine categories at this level. The primary function of these machines involves shaping, cutting, or otherwise processing these hard materials through mechanical means.

Distinguishing this category from its siblings is crucial for accurate classification. While 8464.10.01 covers sawing machines specifically designed for cutting through the aforementioned materials, and 8464.20.01 pertains to machines used for grinding or polishing surfaces, 8464.90.01 includes all other machinery for working these materials that do not fit those specific definitions. Examples might include machines for drilling, milling, or shaping these rigid substances.

Within this "Other" category, further subdivisions exist to provide more granular classification. The subcategory 8464.90.01.10 specifically addresses glass-working machines, indicating a focus on specialized machinery for manipulating glass. The remaining machines within this "Other" classification will fall under 8464.90.01.20, encompassing a broad range of other mechanical devices for working the listed mineral materials and for the cold working of glass that are not otherwise specified.
