7406.20.00.00 - Powders of lamellar structure; flakes

This HTS category, 7406.20.00.00, specifically covers powders and flakes derived from copper that exhibit a lamellar or layered structure. These products are characterized by their thin, plate-like or scale-like physical form, distinguishing them from other copper powder forms. Such materials are often produced through specific manufacturing processes designed to create this layered morphology.

This classification is differentiated from its sibling, 7406.10.00.00, which pertains to copper powders of a non-lamellar structure. The key distinction lies in the physical arrangement of the copper particles: 7406.20.00.00 is for those with a distinct lamellar form, whereas 7406.10.00.00 encompasses powders with irregular, granular, or other non-layered shapes. The manufacturing process and resulting particle morphology are the primary determinants for correct classification between these two headings.

As this is a leaf node within the HTS, there are no further subcategories under 7406.20.00.00. Therefore, classification within this heading relies solely on the physical characteristic of having a lamellar structure. Examples of goods falling under this heading might include certain types of copper flake pigments used in paints and coatings, or specific copper powders used in additive manufacturing or specialized metallurgical applications where a layered particle shape is essential.
