2504 - Natural graphite:

This HTS classification, 2504, encompasses natural graphite. Natural graphite is a naturally occurring allotrope of carbon. It is typically found in crystalline form and is characterized by its soft, slippery nature and excellent electrical and thermal conductivity. This category specifically excludes synthetic graphite, which is manufactured rather than mined.

As a mineral product within Chapter 25, this category is distinct from agricultural products or live animals, as indicated by its sibling categories such as live horses, bovine animals, and poultry. Its placement within Section V highlights its status as a raw or processed mineral material.

The subcategories under 2504 differentiate natural graphite based on its physical form. Subheading 2504.10 specifically covers natural graphite that has been processed into powder or flakes. All other forms of natural graphite, which may include lumps, granular forms, or unprocessed natural graphite deposits, fall under the residual subheading 2504.90.00.00. This distinction is crucial for determining applicable duties and statistical reporting.
