9902.01.73 - Lutetium oxide (CAS No. 12032-20-1) (provided for in subheading 2846.90.80)

This HTS classification, 9902.01.73, specifically covers Lutetium oxide, identified by CAS Number 12032-20-1. This designation falls under Chapter 99, which pertains to temporary legislation and modifications. Notably, Lutetium oxide is provided for in subheading 2846.90.80 of the Harmonized Tariff Schedule, indicating its underlying classification within the main chapters of the HTS. The purpose of this specific 9902 code is to apply temporary measures or restrictions on the import of Lutetium oxide.

Given that this is a leaf node within Chapter 99, there are no further subcategories. The primary distinction for this entry lies not with direct siblings within Chapter 99 (which are typically structured by trade agreement or temporary modification type), but rather by its relationship to its underlying HTS classification in Chapter 28. While other rare earth oxides might be classified under 2846.90.80, this specific 9902 code denotes a particular regulatory treatment, distinct from the general classification of Lutetium oxide if no temporary measures were in effect. Therefore, classification under 9902.01.73 signifies a specific regulatory status that supersedes or supplements the standard tariff treatment.
