Products classified under HTS 2504.90.00.00
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).
Amorphous Natural Graphite Lumps
Irregular lumps of amorphous (microcrystalline) natural graphite mined from metamorphic deposits. Falls under HTS 2504.90.00.00 as 'other' natural graphite not in powder or flake form.
Vein Natural Graphite Crystals
Large crystalline vein graphite chunks, a high-purity form from Sri Lankan deposits. HTS 2504.90.00.00 covers this 'other' natural graphite variety not powdered or in lumps.
Natural Graphite Ore Concentrate
Flotation-concentrated natural graphite ore at 85-90% carbon content, unsintered. Classified in HTS 2504.90.00.00 as 'other' processed natural graphite.
Micronized Natural Graphite Flakes
Delicately milled natural graphite flakes reduced to 5-10 micron size, retaining flake morphology. HTS 2504.90.00.00 as 'other' not meeting powder definition.
High-Purity Lump Natural Graphite
Purified natural graphite lumps >99% carbon for semiconductor applications. Remains under HTS 2504.90.00.00 as unworked 'other' natural graphite.
Natural Graphite Block Scrap
Recovered scrap blocks from natural graphite machining, clean and unsintered. HTS 2504.90.00.00 for 'other' natural graphite forms.
