9902.05.89 - 3,6-Dichloro-2-pyridinecarboxylic acid (CAS No. 1702-17-6) (provided for in subheading 2933.39.25)

This HTS category, 9902.05.89, specifically addresses the import of 3,6-Dichloro-2-pyridinecarboxylic acid, identified by its Chemical Abstracts Service (CAS) number 1702-17-6. This compound is a synthetic organic chemical, often used as an intermediate in the synthesis of other more complex molecules, particularly within the agricultural or pharmaceutical sectors. Its precise chemical structure and intended application are key to its classification under this provision.

As a node within Chapter 99 of the Harmonized Tariff Schedule, this category falls under "Temporary legislation; temporary modifications proclaimed pursuant to trade agreements legislation; additional import restrictions proclaimed pursuant to section 22 of the Agricultural Adjustment Act, as amended." Unlike the broad coverage of general product chapters (e.g., Chapters 1-97), this category signifies a specific, potentially time-limited, regulatory treatment or restriction. Its siblings at the highest level (e.g., 0101 for live horses) cover entirely different classes of goods, highlighting that this Chapter 99 provision is distinct from the general classification of commodities.

Given that 9902.05.89 is a leaf node, there are no further subcategories. Therefore, the classification of 3,6-Dichloro-2-pyridinecarboxylic acid is definitively established at this specific HTS code. Importers must rely on the precise chemical identity and the context provided by the parent Chapter 99 provisions to ensure correct declaration and compliance. The reference to its provision within subheading 2933.39.25 indicates that while it is subject to the temporary measures of Chapter 99, its base classification for other purposes would be in the organic chemicals chapter.
