About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS category, 9902.10.47, specifically covers certain chemical mixtures classified under temporary legislation. The goods are defined as mixtures containing barium carbonate (CAS No. 513-77-9), strontium carbonate (CAS No. 1633-05-2), calcium carbonate (CAS No. 471-34-1), and 1-methoxy-2-propanyl acetate (CAS No. 108-65-6). Crucially, these mixtures must be of a kind intended for use as emitter suspension cathode coating. This specialized application is the primary defining characteristic of the goods within this HTS code.

As a category within Chapter 99, which pertains to temporary legislation and special provisions, this code stands apart from the broader, more permanent classifications found in earlier chapters of the HTS. While the constituent chemicals might individually fall under different chemical-related chapters, their combination and intended use as a cathode coating directs them to this specific, temporary classification. It is important to note that this is a leaf node, meaning there are no further subdivisions within this particular HTS code. Classification under 9902.10.47 is contingent upon meeting all specified composition and use criteria, and it is provided for under subheading 3824.90.92 of the permanent tariff schedule, highlighting its provisional nature.
