2805.30.00.10 - Cerium 🖩

This HTS category, 2805.30.00.10, specifically covers pure Cerium, which is a chemical element classified as a rare-earth metal. It falls under the broader heading of inorganic chemicals and is distinct from other rare-earth metals due to its unique atomic structure and chemical properties. Cerium is characterized by its silvery-white appearance and its reactivity, particularly with air and acids.

Distinguishing Cerium from its sibling categories is crucial for accurate classification. While categories like 2805.30.00.05 (Lanthanum), 2805.30.00.15 (Praseodymium), and 2805.30.00.20 (Neodymium) also represent individual rare-earth metals, each possesses distinct physical and chemical characteristics that differentiate them for trade purposes. This specific code applies only to Cerium itself, not to alloys or mixtures containing Cerium unless it is the primary component and clearly identified as such within the broader context of the rare-earth metals heading.

As this is a leaf node within the HTS, there are no further subcategories. Classification under 2805.30.00.10 requires the material to be identified as elemental Cerium, free from significant alloying with other metals or significant contamination by other elements that would warrant classification under a different heading or subheading. The primary criterion for classification here is the identity of the metal as pure Cerium.
