9902.07.54 - 2H-3,1-Benzoxazine-2,4(1H)-dione (Isatoic anhydride) (CAS No. 118-48-9) (provided for in subheading 2934.99.90)

HTS Code 9902.07.54 specifically covers 2H-3,1-Benzoxazine-2,4(1H)-dione, also known as Isatoic anhydride. This substance, identified by CAS No. 118-48-9, is a chemical compound. Its inclusion within Chapter 99 of the Harmonized Tariff Schedule indicates it is subject to temporary legislation, modifications, or additional import restrictions, often proclaimed pursuant to trade agreements or specific agricultural acts like Section 22 of the Agricultural Adjustment Act.

This particular HTS code is distinct from the broader categories found in the main Chapters of the HTS (e.g., Chapters 01-97) which classify goods based on their inherent nature, material, or primary use. While Isatoic anhydride may have applications that could potentially link it to other chapters (e.g., as a chemical intermediate under Chapter 29), its presence in Chapter 99 signifies a specific, temporary trade-related regulatory treatment rather than a permanent classification based on its inherent properties alone.

As this is a leaf node within the HTS database, there are no further subcategories. Classification under 9902.07.54 is definitive for Isatoic anhydride when it falls under the provisions of Chapter 99. Importers and exporters must adhere to the specific conditions and restrictions associated with this temporary classification, which are detailed within the relevant trade legislation and proclamations.
