Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If crushed into powder after import
Post-import processing to powder changes classification to 2504.10 for statistical reporting.
If containing slag or processing residues
Graphite slag or residues from beneficiation classified under Chapter 26 as mineral wastes.
If further processed into carbon electrodes
Electrodes of graphite, even from natural sources, fall under Chapter 85 as electrical articles.

Import Tips & Compliance
• Provide mining certificates proving natural origin to distinguish from synthetic graphite under 2504.90
• Declare exact lump sizes; oversized may require statistical breakouts within 2504.90
• Check for radioactivity declarations if sourced from certain deposits
