7406.10.00.00 - Powders of non-lamellar structure

This HTS category, 7406.10.00.00, specifically classifies copper powders that are of a non-lamellar structure. This means the particles are generally irregular, spherical, or dendritic in shape, rather than flat and plate-like. These powders are typically produced through methods such as atomization, electrolysis, or chemical reduction, resulting in a granular or particulate form that lacks the distinct layered appearance characteristic of lamellar structures.

It is crucial to differentiate this classification from its sibling category, 7406.20.00.00, which covers copper powders of a lamellar structure and flakes. Lamellar structures, by definition, possess a flattened, plate-like morphology. Therefore, the primary distinguishing factor lies in the physical form of the copper particles; non-lamellar powders lack this flattened, layered characteristic.

As this is a leaf node in the HTS classification system, there are no further subcategories. Classification within 7406.10.00.00 is solely determined by the non-lamellar nature of the copper powder. Examples of goods falling under this heading include atomized copper powder used in brazing pastes, sintered components, and certain chemical applications where the particle shape is critical for performance.
