Amorphous Natural Graphite Lumps
Irregular lumps of amorphous (microcrystalline) natural graphite mined from metamorphic deposits. These lumps are in a crude or crushed state, not processed beyond washing, crushing, or grinding, and are not in flake or powder form, thus falling under 'other' natural graphite.
2504.90.00High-Purity Lump Natural Graphite
Purified natural graphite lumps with over 99% carbon content, intended for semiconductor applications. The lumps are unworked and not processed beyond washing or crushing, so they remain classified as 'other' natural graphite, even with high purity.
2504.90.00Natural Graphite Block Scrap
Recovered scrap blocks from natural graphite machining, clean and unsintered. These blocks are in a crude or waste state, not processed beyond crushing or grinding, and are not powder or flake, so they fall under 'other' natural graphite.
2504.90.00Natural Graphite Ore Concentrate
Flotation-concentrated natural graphite ore at 85-90% carbon content, unsintered. The ore has been concentrated by flotation, a mechanical or physical process allowed by Chapter 25 notes, and is not in powder or flake form, so it falls under 'other' natural graphite.
2504.90.00Vein Natural Graphite Crystals
Large crystalline vein graphite chunks, a high-purity form from Sri Lankan deposits. These chunks are in a crude state, not powdered or flaked, and are not processed beyond washing or crushing, so they fall under 'other' natural graphite.
