9902.01.72 - Lanthanum carbonate (CAS No. 54451-24-0) (provided for in subheading 2846.90.80)

This HTS category, 9902.01.72, pertains to Lanthanum carbonate (CAS No. 54451-24-0) when specifically provided for under this temporary or special classification provision. This designation indicates that while Lanthanum carbonate would typically fall under subheading 2846.90.80 of the Harmonized Tariff Schedule, its importation is subject to the specific rules and restrictions outlined within Chapter 99. Chapter 99 encompasses temporary legislation, modifications proclaimed pursuant to trade agreements, and additional import restrictions enacted under Section 22 of the Agricultural Adjustment Act.

Unlike the primary product categories found in earlier chapters of the HTS, such as live animals (Chapters 01), this specific subheading does not represent a broad class of goods. Instead, it serves as a mechanism to apply unique tariff or trade treatment to a precisely defined chemical compound. The key differentiator for goods classified here is the explicit reference to this specific Lanthanum carbonate entry, implying a departure from its standard tariff treatment due to prevailing trade policies or legislative actions.

As this classification is a leaf node, there are no further subcategories within 9902.01.72. Therefore, classification within this heading is definitive for Lanthanum carbonate when subject to the provisions of Chapter 99. Importers should carefully review any accompanying notes or proclamations linked to this temporary classification to ensure full compliance with all applicable requirements, which may include specific quotas, duties, or documentary evidence.
