2504.10 - In powder or in flakes:

This category encompasses natural graphite that is presented in a powdered or flaked form. Natural graphite, a crystalline form of carbon, is valued for its lubricating, conductive, and refractory properties. Goods classified under 2504.10.00 are specifically those where the graphite has undergone processing to reduce it to powder or flake dimensions, making it suitable for various industrial applications such as lubricants, battery electrodes, and crucibles.

In contrast to its sibling category, 2504.90.00.00 "Other," this heading exclusively pertains to graphite that has been specifically processed into a powder or flake form. The sibling category would cover natural graphite in other physical states, such as lump or massive forms, that have not been specifically reduced to powder or flake.

Within this category, further distinctions are made to refine classification. Subcategories such as 2504.10.10.00 "Crystalline flake (not including flake dust)" and 2504.10.50.00 "Other" recognize variations in flake size and the presence of finer particles, often referred to as dust. These subcategories allow for more precise classification based on specific physical characteristics relevant to the intended industrial use and potential quality differences.
