2504.90.00.00 - Other

This classification, HTS Code 2504.90.00.00, covers natural graphite that does not fall under the preceding category for graphite in powder or flake form. It encompasses all other forms of natural graphite, including but not limited to, massive lumps, crystalline aggregates, or amorphous varieties that are not processed into fine powders or distinct flakes. The key criterion for inclusion here is the absence of processing that results in the specified granular forms.

Distinguishing this category from its sibling, 2504.10 (In powder or in flakes), is crucial. The sibling category specifically addresses natural graphite that has undergone processing to break it down into a powdered state or to form characteristic flakes. This residual category, 2504.90.00.00, is for graphite that remains in its naturally occurring, larger, or less processed forms, before any significant size reduction or structural alteration that would classify it as powder or flake.

As a leaf node within the HTS, this category has no further subcategories. Therefore, classification decisions will rely on accurately determining whether a given natural graphite product meets the criteria for powder or flakes (HTS 2504.10) or if it remains in a more unrefined, massive, or amorphous state, thus falling under this residual "Other" classification. The physical form and degree of processing are the primary determinants for accurate classification.
