This HTS category, 9902.01.71, specifically classifies Lanthanum(III) oxide, identified by CAS number 1312-81-8. This compound is a rare earth oxide and its classification within Chapter 99 indicates it is subject to temporary legislation or modifications, often related to trade agreements or specific import restrictions proclaimed under Section 22 of the Agricultural Adjustment Act. While its base material falls under Chapter 28 (Inorganic Chemicals), its presence in Chapter 99 signifies a special tariff treatment.

As a leaf node within the HTS database, this category does not have further subcategories. Its specific inclusion in Chapter 99 differentiates it from the general classification of inorganic chemicals found in other chapters, highlighting a distinct regulatory status. Importers and customs brokers must carefully consult the specific proclamations and legislation associated with this subheading to understand the applicable duties, quotas, or other import requirements beyond the standard tariff rates. The "provided for in subheading 2846.90.80" note clarifies its underlying chemical classification, but the Chapter 99 designation takes precedence for its current import status.
