2504.10.10.00 - Crystalline flake (not including flake dust) 🖩

This HTS category, 2504.10.10.00, specifically classifies crystalline graphite in flake form, excluding any fine dust or powder that may result from its processing. The key characteristic is its distinct, visible flake structure, which is larger and more defined than powdered graphite. This material is primarily used in applications where the physical properties of graphite, such as lubrication, thermal conductivity, and electrical conductivity, are desired in a particulate form with a specific morphology.

It is crucial to distinguish this classification from its sibling category, 2504.10.50.00, which covers "Other" forms of natural graphite in powder or flakes. While both fall under the broader heading of natural graphite in powder or flakes, 2504.10.10.00 is reserved solely for the crystalline flake variety. The sibling category would encompass powdered graphite or any flake material that does not meet the stringent definition of crystalline flake, or if the physical form is predominantly dust.

As this is a leaf node, there are no further subcategories. Therefore, classification within this code hinges on the precise visual and physical identification of crystalline graphite in its flake form. Importers and exporters must ensure that the product exhibits the characteristic lamellar structure of crystalline graphite and is not a fine, powdery material to correctly apply this specific tariff number.
