9902.01.56 - Barium dinitrate (CAS No. 10022-31-8) (provided for in subheading 2834.29.51)

HTS Code 9902.01.56 specifically addresses Barium dinitrate (CAS No. 10022-31-8). This classification falls under Chapter 99 of the Harmonized Tariff Schedule, which is designated for temporary legislation, temporary modifications proclaimed pursuant to trade agreements, and additional import restrictions proclaimed pursuant to Section 22 of the Agricultural Adjustment Act, as amended. Therefore, the goods classified under this code are subject to specific, often time-limited, import regulations beyond the standard tariff classifications found in earlier chapters.

While this category is at the root level of the HTS database, its function is distinct from the primary product chapters (e.g., Chapters 01-97). Chapters like 01 (Live Animals) cover entirely different classes of goods based on biological classification and immediate purpose. HTS 99 codes are not descriptive of inherent product characteristics but rather of the regulatory overlay applied to goods, regardless of their underlying material composition or function.

As a leaf node, HTS Code 9902.01.56 does not have subcategories. The classification of Barium dinitrate under this code implies that its import is subject to special provisions, likely related to agricultural policy or trade agreements, overriding or supplementing its standard classification under subheading 2834.29.51. Importers must carefully consult the specific terms and conditions associated with this 9902 code to ensure compliance with all applicable temporary legislation and restrictions.
