7903.90.60.00 - Other

This HTS category, 7903.90.60.00, encompasses zinc in forms that are neither dust nor powders. It is intended for zinc that does not precisely fit the definitions of "dust" or "powders" as outlined in related subheadings within Chapter 79. This category serves as a residual catch-all for zinc forms that do not conform to more specific classifications within the zinc dust, powders, and flakes heading.

Distinguishing this category from its sibling, 7903.90.30.00 (Powders), is crucial. While "powders" typically refers to very fine, granular particles, this subheading is for zinc in other particulate or fragmented forms. Examples could include zinc flakes, which are thin, flat particles, or other irregularly shaped metallic fragments that are not considered dust (extremely fine particles) or powders (generally uniform, fine particles). The classification will depend on the physical form, particle size, and manufacturing process of the zinc.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, classification into this subheading relies entirely on the exclusion from other more specific classifications of zinc dust and powders, and the positive identification of the goods as being made of zinc and falling under the broader scope of zinc dust, powders, and flakes, but not fitting the narrower definitions of "powders."
