2805.30.00.15 - Praseodymium

This HTS category covers elemental praseodymium, a rare-earth metal. Praseodymium is classified here when it is in its pure, unmixed, or unalloyed form. This means that the metal is primarily praseodymium and does not contain significant quantities of other metals or elements beyond trace impurities inherent to its production. Its physical form can vary, including ingots, powders, or other refined shapes, provided it remains essentially pure praseodymium.

Distinguishing praseodymium from its sibling categories at this level is crucial for accurate classification. While all fall under "Rare-earth metals, scandium and yttrium, whether or not intermixed or interalloyed: Not intermixed or interalloyed," this specific code is reserved solely for praseodymium. For instance, HTS code 2805.30.00.05 is for Lanthanum, 2805.30.00.10 for Cerium, and 2805.30.00.20 for Neodymium. Each code denotes a distinct elemental rare-earth metal.

As this is a leaf node in the HTS database, there are no further subcategories to introduce. Classification under 2805.30.00.15 is final for pure praseodymium. If the praseodymium were mixed or alloyed with other metals, it would fall under a different HTS classification, likely within the "intermixed or interalloyed" provisions. Therefore, the purity and elemental identity of the material are the primary determinants for classification under this specific code.
