High-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.

Import Tips & Compliance
• Confirm the purification process does not involve roasting or calcining, which would exclude it from Chapter 25
• Provide a certificate of analysis to substantiate the carbon content and purity
• Check if the product is considered an optical element or cultured crystal, which would shift classification
Related Products under Tariff item 2504.90.00
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.
Natural 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.
Natural 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.
Vein 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.
