7603.20.00.00 - Powders of lamellar structure; flakes

This HTS category, 7603.20.00.00, specifically covers aluminum powders and flakes characterized by a lamellar (plate-like or scale-like) structure. These products are formed through processes that result in thin, flat particles, distinguishing them from other forms of aluminum powder. Such materials are often utilized for their specific aesthetic or functional properties in various industrial applications.

It is crucial to differentiate this classification from its sibling, 7603.10.00.00, which pertains to aluminum powders of non-lamellar structure. The primary distinction lies in the physical morphology of the particles. While both are aluminum powders, 7603.20.00.00 is exclusively for those exhibiting a distinct lamellar or flaky appearance, whereas 7603.10.00.00 covers granular, spherical, or irregular shaped powders.

As a leaf node within the HTS, this category does not have further subcategories. Therefore, classification under 7603.20.00.00 relies on a clear determination of the lamellar structure of the aluminum powder or flakes. Examples of products falling into this category include metallic pigments used in paints and coatings, printing inks, and certain specialized composite materials where the lamellar form is essential for performance or appearance.
