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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the graphite is in powder or flake form
Heading 2504 distinguishes powder or flake from other forms; this item covers those forms.

Import Tips & Compliance
• Ensure the lumps are not roasted, calcined, or mixed, as that would exclude them from Chapter 25
• Declare the carbon content and origin clearly to support classification
• Verify whether an anti-dusting agent is added, as it must not make the product suitable for a specific use
Related Products under Tariff item 2504.90.00
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.
Micronized Natural Graphite Flakes
Micronized natural graphite flakes are finely milled particles (5-10 microns) that retain their flake structure. They fall under tariff item 2504.90.00 as 'other' natural graphite, since they are not classified as powder or crystalline powder under other headings.
Natural Flake Graphite Powder
Natural flake graphite powder is a fine powder derived from natural flake graphite, used in lubricants, pencils, and refractories. It is classified under tariff item 2504.90.00 as 'other' natural graphite, distinct from powdered (2504.10) or lump forms.
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.
