9902.07.72 - N-{3-[(2R)-2-amino-1-(methylsulfamoyl)propan- 2-yl]-4-fluorophenyl}-5-fluoropyridine-2-carboxamide (CAS No.1877329-50-4) (provided for in subheading 2935.90.75)

This HTS category, 9902.07.72, specifically classifies N-{3-[(2R)-2-amino-1-(methylsulfamoyl)propan-2-yl]-4-fluorophenyl}-5-fluoropyridine-2-carboxamide, identified by CAS Number 1877329-50-4. This is a highly specialized chemical compound, typically a pharmaceutical intermediate or an active pharmaceutical ingredient (API). Its inclusion within Chapter 99 signifies a temporary classification provision, often related to specific trade agreements, import restrictions, or legislative adjustments. The parent context of Section XXII and Chapter 99 underscores that this classification is governed by special rules rather than the standard commodity chapters.

Unlike the broader categories at the root of the HTS database, such as live animals (Chapters 01) or agricultural products, this node pertains to a precisely defined chemical substance with a specific molecular structure and scientific identification. The sibling categories at the same level are numerous and cover a vast array of goods. However, the critical distinguishing factor for 9902.07.72 is its precise chemical identity and its placement within a chapter designated for temporary or special tariff treatments, indicating it is not a general commodity.

As a leaf node, HTS category 9902.07.72 does not possess further subcategories. Therefore, classification within this code relies entirely on the exact match of the imported substance to the described chemical name and CAS number. Importers must ensure the product fully corresponds to the specifications outlined in the description to correctly apply this temporary tariff provision. The reference to "provided for in subheading 2935.90.75" in its description suggests that while it falls under this special provision, its underlying chemical nature might align with the general classification of sulfonamides and related compounds in Chapter 29, further emphasizing the distinct role of Chapter 99.
