Overview

This HTS category, 9902.01.61, specifically covers zirconium basic carbonate, also known as zirconium(4+) dicarbonate. This compound, identified by CAS No. 57219-64-4, is recognized and classified for import purposes under subheading 2836.99.50, indicating its nature as a salt of carbonic acid. Its inclusion in Chapter 99 signifies that it is subject to temporary legislation, modifications pursuant to trade agreements, or additional import restrictions as proclaimed under Section 22 of the Agricultural Adjustment Act.

As a leaf node within Chapter 99, this category does not have further subcategories. Its specific designation highlights a particular chemical compound that is subject to special regulatory treatment beyond its standard classification.
