Natural Flake Graphite Powder
Fine powder derived from natural flake graphite, used in lubricants, pencils, and refractories. Classified under HTS 2504.90.00.00 as 'other' natural graphite, distinct from powdered (2504.10) or lumps (2504.90 but specified as other forms).

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ground to fine powder under specific fineness
Natural graphite in powder form with defined particle size falls under 2504.10, separate from coarser 'other' forms.
If chemically processed into graphite lubricant paste
Artificial graphite preparations or chemically treated products shift to Chapter 38 as chemical preparations.
If agglomerated into blocks or sheets for industrial use
Agglomerated or built-up graphite products are classified under Chapter 68 as worked mineral products.

Import Tips & Compliance
• Verify purity and carbon content via lab certification to confirm natural graphite classification and avoid reclassification as synthetic
• Include geological origin documentation, as some countries have export quotas on natural graphite
• Ensure particle size specs match 'other' category; powders under 1mm may risk heading 2504.10
